Everything in the `.vs` folder should be excluded from your source repository. It is a folder created by Visual Studio for storing user specific information. Previously there was a `.suo` file which held this data.The change came from a [UserVoice suggestion](https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/6079923-store-project-related-information-in-vs-folder-to).

Additionally, there&#39;s a very useful GitHub repo that has common `.gitignore` files for various project types and you will see that the [Visual Studio](https://github.com/github/gitignore/blob/master/VisualStudio.gitignore) version completely [excludes this folder](https://github.com/github/gitignore/blob/master/VisualStudio.gitignore#L31) too.



Even after adding the .vs folder like the answer correctly suggested, I still had issues with the storage.ide being in my branch and not being able to switch. I tried clearing the git cache like [this answer][1] suggested, but it was still blocking me switching branches.

I soon realised though that I was the one being stupid and I had VS2015 and VS2017 open with the same project (and obviously same repo) and 2017 was blocking the storage.ide file. 

Closing 2015 and ignoring the storage.ide file in VS2017 sorted this issue. 

Hope this might help others..

For my admin panel I extract all the assets including the `manifest-json.js` to `mix.setPublicPath(path.normalize(&#39;public/backend/&#39;))`.

All the files get correctly added to the backend folder, and the `manifest-json.js` file looks as follows:

    {
        // all correct here
        &quot;/js/vendor.js&quot;: &quot;/js/vendor.js&quot;,
        &quot;/js/app.js&quot;: &quot;/js/app.js&quot;,
        &quot;/css/app.css&quot;: &quot;/css/app.css&quot;,
        &quot;/js/manifest.js&quot;: &quot;/js/manifest.js&quot;
    }

the problem is that when using 

    {{ mix(&#39;backend/css/app.css&#39;) }}

in my blade-files, it looks in `public/manifest-json.js` instead of looking for it in `backend/manifest-json.js`.

How can I make sure the right `manifest-json.js` file is used?


The Mix manifest does not exist when it does exist

Recently I&#39;ve been working on building a tree-view component library for Angular, as [ngx-tree](https://github.com/e-cloud/ngx-tree).

## Problem
Soon after I figured out how to implement a **virtual-scroll feature** for this library for performance with large data set, and got it to run properly in Firefox, I am trapped by a weird scrolling behavior in **[Blink](https://en.wikipedia.org/wiki/Blink_(web_engine))-included browsers**(like Chromium, Chrome, Opera).

## Demo link

&gt; Here is the demo plunkr -- &lt;del&gt;https://embed.plnkr.co/xMpmK5EBC46tDKpYFpw8&lt;/del&gt; see Update #1 below

## Situation

* In Firefox, Edge and IE 11, my library with virtual scroll feature works in expectation with smooth scrolling.
* However, in Chrome and Opera, when I scroll to some positions inside the tree-view, the position of the scrollbar(which is the `scrollTop` property of scroll area) jump up and down, causes a **flickering** tree-view and break down the virtual-scroll feature.

### browser detail version

* Chrome - 59.0.3071.115
* Firefox - 54.0
* Edge - 40.15063.0.0

### other browsers

In China, there are some **shelled** browsers derived from Chromium project(like 360se, QQ browser, Sogou browser, UC browser) with **older version of V8 and blink**. And they don&#39;t have that weird scroll behavior.

### Some Assumption

Is it caused by some optimization on the scroll implementation(like smooth scrolling) by the Chromium team?

Hope to get some guides!!! (≧﹏ ≦)

---

**Update #1**

&gt; Demo link update with event log: https://embed.plnkr.co/GpQBZsguhZZOQWWbZnqI/   

**One must test the scrolling before opening devtool to see the logs**

I have to explain a little more how the virtual-scrolling works and what&#39;s causing the flickering.

First, see the [design of Virtual Scrolling](https://github.com/e-cloud/ngx-tree/blob/feature/virtual-scroll/src/lib/services/virtual-scroll.md).

A key point of virtual scrolling is， we create a fake scroll area the same size as that area without virtual scrolling instrumented. So in an optimal situation, the scrollbar position of the scroll area ought not to change until some expected events trigger its changes. For scroll event, we update the view for every animation frame.

Within a height-fixed scrolling area, we assume a truth that the scrollTop property will not change **with a large percentage**, if we simulate the those unrendered elements&#39; height properly(there could be **a bit of deviation for the calculation accuracy**) within an animation frame.

However, based on my observed results, the blink-series browsers seems to perform a different strategy to update the scrollTop of the scrollable element. Its timing to update the scrollTop is different than none-blink-series browsers. That all I&#39;ve figured out so far.

I just installed Visual Studio 2017 15.3 preview, and now I&#39;m noticing a new file beneath an existing solution that I&#39;ve been working on:

    .vs\[SOLUTION NAME]\v15\sqlite3\storage.ide

I&#39;m wondering if I should be adding this to my version control repo, or if I should put it on the ignore list (i.e. if it&#39;s a user/setting based file, like .suo files).  I&#39;ve been googling trying to figure out what it is and what it does, but there&#39;s barely any info about it.  I&#39;ve searched things like &quot;visual studio sqlite3 storage.ide&quot; which have lead me to pages [like this reference source for the `SQLitePersistentStorageService` class][1], so I gather it has something to do with code analysis, but I can&#39;t find any other information at all about the `SQLitePersistentStorageService` class.

What is this file for, and should I be keeping it in version control?

I&#39;m trying to do a simple Azure Function to learn about it. There will be 3 functions: 

- 1 function to insert a row into a table of a database. This table will contain the current date and a string parameters typed by the user and passed by GET.
- 1 function similar to the previous one, but passing the parameter by POST.
- 1 function to read the table and show its content.

I&#39;ve been able to do the first and the third ones. But I can&#39;t pass the parameter by POST. I&#39;ve looked for examples but I couldn&#39;t run them with success. The client app is a Windows Forms one.

Could anyone show me an example anout how to pass parameters by POST to the function and how to read them?

Thank&#39;s in advance


EDIT:

Here&#39;s the code to pass the parameters by GET (this is working fine):

	private void button2_Click(object sender, EventArgs e)
	{
		string cadena = lsql1.Text + &quot;?notas=&quot; + tNotas.Text;

		try
		{
			HttpWebRequest req = (HttpWebRequest)WebRequest.Create(cadena);
			HttpWebResponse res = (HttpWebResponse)req.GetResponse();

			if (res.StatusCode == HttpStatusCode.OK)
			{
				MessageBox.Show(&quot;Grabado&quot;);
			}
			else
			{
				MessageBox.Show(res.StatusDescription);
			}
		}catch (WebException ex)
		{
			using (Stream s = ex.Response.GetResponseStream())
			{
				StreamReader sr = new StreamReader(s);
				string text = sr.ReadToEnd();
				text = text.Substring(1, text.Length - 2);
				sr.Close();
				text = text.Replace(&quot;\\&quot;, &quot;&quot;);
				text = &quot;{&quot; + text + &quot;}&quot;;
				Error mensajeError = JsonConvert.DeserializeObject&lt;Error&gt;(text);

				MessageBox.Show(mensajeError.ExceptionMessage);
			}
			
		}
	}

And here&#39;s the code to receive it and do the insert (this is working too):

    [FunctionName(&quot;sql1&quot;)]
	public static async Task&lt;HttpResponseMessage&gt; Run(HttpRequestMessage req, TraceWriter log)
	{
		try
		{
			log.Info(&quot;C# HTTP trigger function processed a request.&quot;);

			var cnnString = &quot;Server=SERVIDOR;Database=base_prueba;User ID =azure;Password=0000;Trusted_Connection=False;Encrypt=False;&quot;;

			using (SqlConnection connection = new SqlConnection(cnnString))
			{
				connection.Open();
				SqlCommand cmd = connection.CreateCommand();

				DateTime fecha = DateTime.Today;
				
				string notas = req.GetQueryNameValuePairs()
				.FirstOrDefault(q =&gt; string.Compare(q.Key, &quot;notas&quot;, true) == 0)
				.Value;

				// insert a log to the database
				cmd.CommandText = &quot;INSERT INTO Prueba_Azure (fecha, notas) VALUES (&#39;&quot; + fecha.ToString() + &quot;&#39;, &#39;&quot; + notas + &quot;&#39;)&quot;;
				cmd.ExecuteNonQuery();
			}

			// Get request body
			dynamic data = await req.Content.ReadAsAsync&lt;object&gt;();

			return name == req.CreateResponse(HttpStatusCode.OK, &quot;Done&quot;);
		}
		catch (Exception ex)
		{
			HttpResponseMessage res = req.CreateErrorResponse(HttpStatusCode.InternalServerError, ex);
			return res;
		}
	}

What I&#39;m looking for is to to this by POST

How to pass parameters by POST to an Azure function?

I am creating a SSIS project via Biml (Using the current version of BimlExpress per the [Varigence BimlExpress page](https://www.varigence.com/BimlExpress)) that uses a script component within a Data Flow Task.  The project is created without issue however errors when it gets to the Script Component:

&gt;Could not load file or assembly &#39;Microsoft.SqlServer.DTSPipelineWrap, Version=14.100.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91&#39; or one of its dependencies. The system cannot find the file specified.

&gt;at ScriptMain.PreExecute()
   at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()

I can see this dll within the GAC and when I try to add the reference manually, SSIS states that I can&#39;t add it as it is already included in the project.

However, if I open the Script Component and manually `Build` it - but change nothing else - the Data Flow Task will run through without issue.

To clarify, I know I have changed nothing else as I am recreating this project from the Biml each time I want to test a new approach, which provides a consistent baseline.

---

Does anyone know why a Script Component that includes a reference to a GAC dll, will only work when manually `Built` but not beforehand?

I have used this exact Biml before without issue, though on a different environment.  Worked using Visual Studio 2012 against a SQL Server 2016 instance yet doesn&#39;t here within Visual Studio 2015 (targeting 2012) against a SQL Server 2016 instance.

For further context I have also tested this outputting the SSIS Project targeted at SQL Server 2012, 2014 and 2016 with the exact same error message.

---

#Update

This appears to definitely be a dll version problem in the project as output from BimlExpress, in that if I manually create the `v4.0_14.100.0.0__89845dcd8080cc91` folder with the version 13 dll inside at `C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.DTSPipelineWrap` the script component now errors out with the following:

&gt;System.InvalidCastException: Unable to cast COM object of type &#39;System.__ComObject&#39; to interface type &#39;Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSComponentMetaData100&#39;.

I&#39;m using VS 15.3, which supports integrated CMake 3.8. How can I target C++17 without writing flags for each specific compilers? My current global settings don&#39;t work:

    # https://cmake.org/cmake/help/latest/prop_tgt/CXX_STANDARD.html
    set(CMAKE_CXX_STANDARD 17)
    set(CMAKE_CXX_STANDARD_REQUIRED ON)
    set(CMAKE_CXX_EXTENSIONS OFF)

    # expected behaviour
    #set(CMAKE_CXX_FLAGS &quot;${CMAKE_CXX_FLAGS} /std:c++lastest&quot;)

I expected CMake to add &quot;/std:c++lastest&quot; or equivalents when generating VS solution files, but no c++17 flags was found, resulted in compiler error:

    C1189 #error: class template optional is only available with C++17.

VS 2017 (and maybe olders versions) gives me this handy little constructor shortcut to generate a `private readonly` field and assign it.

Screenshot:

[![enter image description here][1]][1]

This ends up generating a private member called `userService` and then assigns it with:

    this.userService = userService;

This goes against the code style that I use which is to name all private members with a prefix `_` resulting in assignment that should look like:

    _userService = userService;

How can I make it so that VS obeys this code style rule with its code generation shortcuts?

I have a big project(let&#39;s say `A repo`), and it there one child folder which is come from `B repo`.  I would meet warning like below when I commit from `A repo`

    warning: adding embedded git repository: extractor/annotator-server
    hint: You&#39;ve added another git repository inside your current repository.
    hint: Clones of the outer repository will not contain the contents of

    hint:
    hint:   git rm --cached extractor/annotator-server
    hint:
    hint: See &quot;git help submodule&quot; for more information.

I have seen `git-submodule` and `git-subtree`:

https://stackoverflow.com/questions/36236484/maintaining-git-repo-inside-another-git-repo

https://www.atlassian.com/blog/git/alternatives-to-git-submodule-git-subtree

But I don&#39;t like them , because they need extra config.

--------------

What I want is , for example:

structure like:

    A/
    --- a.py
    
    --- B/
    --- B/b.py

When I change `B/b.py` .

1. If I am on path `A/` ,  `git add` can detect `B/b.py` changed, `git push` only commit that to A repo.  

        git add .   (would add changes under A/  )
        git push   (would push changes under A/  )
        git pull   (would pull changes under A/  )
        git clone XXX:A  (would clone all files under A/ ,    A/B/ is just looks like plain folder with all files, not a repo )



2. If I am on path `A/B/` , `git add` only add `B/b.py` changes to B repo,  and `git push` only commit that to B repo. 


        git add .   (would add changes under B/ , but not add changes to A repo)
        git push   (would push changes under B/ , but not push changes to A repo)
        git pull   (would clone changes under B/ ,  )
        git clone XXX:B  (would clone all files under B/  )

3. Once I want to snyc A and B in another machine, just do


        git clone A
        rm -rf A/B/
        git clone B ./B
        git add . &amp;&amp; git commit &#39;sync with B&#39;


In another word, A and B act as a standalone repo.


But the truth is , A repo treat B repo as submodule:  

A repo
https://github.com/eromoe/test

B repo
https://github.com/eromoe/test2
   
-----------------

How do I force A repo track all files under `A/` , and B repo track all files under `A/B/` ?   I want A and B act as a self-contain repo , without any other config.

Quoting Linus Torvalds when asked how many files Git can handle during his [Tech Talk at Google in 2007](https://www.youtube.com/watch?v=4XpnKHJAok8) (43:09):

&gt;&amp;hellip;Git tracks your content. It never ever tracks a single file. You cannot track a file in Git. What you can do is you can track a project that has a single file, but if your project has a single file, sure do that and you can do it, but if you track 10,000 files, Git never ever sees those as individual files. Git thinks everything as the full content. All history in Git is based on the history of the whole project&amp;hellip;

&lt;sup&gt;(Transcripts [here](https://gist.github.com/dukeofgaming/2150263).)&lt;/sup&gt;

Yet, when you dive into [the Git book](https://git-scm.com/book/), the first thing you are told is that a file in Git can be either *tracked* or *untracked*. Furthermore, it seems to me like the whole Git experience is geared towards file versioning. When using `git diff` or `git status` output is presented on a per file basis. When using `git add` you also get to choose on a per file basis. You can even review history on a file basis and is lightning fast.

How should this statement be interpreted? In terms of file tracking, how is Git different from other source control systems, such as CVS?


What does Linus Torvalds mean when he says that Git &quot;never ever&quot; tracks a file?

I&#39;m wondering if there&#39;s a way to avoid having to type the word `git` at the beginning of every Git command.

It would be nice if there was a way to use the `git` command only once in the beginning after opening a command prompt to get into *&quot;Git mode&quot;*.

For example:

    git&gt;

After which every command we type is by default interpreted as a Git command. 

In a way similar to how we use the MySQL shell to write database commands:

    mysql&gt;

This will save me from having to type `git` hundreds of times a day.

**NOTE:** I&#39;m using [`git-bash`](https://stackoverflow.com/questions/tagged/git-bash), on Windows.

How do I avoid typing &quot;git&quot; at the begining of every Git command?

I am facing a strange issue from roslyn compiler. Sometimes when I build the solution I face a strange issue in error list which does not let me build the solution. Here is the error:

 1. I try to clean the solution and rebuild it but does not work again.
    
 2. Tried to delete files manually but again shows an error pointing out
    I do not have right permissions to do this:
    
 3. Tried deleting from `CMD` but again shows the same error:

[![Image when trying to delete files manually][1]][1]

The only way to delete roslyn generated files is by restarting the PC and when restarted I can delete them manually without a problem.

I am administrator in my PC so there is no problem with that I guess.

This problem seems to happen in Visual Studi0 2015 and Visual Studio 2017.

I dont like restarting the PC 4-5 times a day or more thats why I am asking here.

Some other details:

 - I am the one who created this project so theoretically it should not
   be a problem to do this action.
   
 - When the project first created I did run the Visual Studion in
   Administrator Mode as I am doing now.
 - I am using ASP.MVC 5 template in my project.
 - Files which do not get deleted are `bin/roslyn/csc` and `bin/roslyn/VBCSCompiler`.

I could find a solution to remove this part from web.config so it does not generate those files:


    &lt;compilers&gt;
      &lt;compiler language=&quot;c#;cs;csharp&quot; extension=&quot;.cs&quot; type=&quot;Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35&quot; warningLevel=&quot;4&quot; compilerOptions=&quot;/langversion:6 /nowarn:1659;1699;1701&quot; /&gt;
      &lt;compiler language=&quot;vb;vbs;visualbasic;vbscript&quot; extension=&quot;.vb&quot; type=&quot;Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35&quot; warningLevel=&quot;4&quot; compilerOptions=&quot;/langversion:14 /nowarn:41008 /define:_MYTYPE=\&amp;quot;Web\&amp;quot; /optionInfer+&quot; /&gt;
    &lt;/compilers&gt;

But this solution would cause problem with new c# 6 features so I can not remove this section.....

Furthermore I tried this command in CMD to see if there is a process locking this file but anyway it did not show me any process at all:

    C:\WINDOWS\system32&gt;tasklist /m D:\SealogicalNewWebsite\SealogicalWebsite\SealogicalWebsite\bin\roslyn\csc.exe
    INFO: No tasks are running which match the specified criteria.

Does anybody knows a way how to handle this strange issue ?

How can I refresh the list of remote branches in my Visual Studio Team Explorer panel?

In the Visual Studio 2017 Team Explorer, Branches panel, I could see the 10 or so branches in our VSTS instance. 

Then in Chrome, I deleted some of the older branches and created a new branch. 

Switched back to VS 2017, but the list of `remotes/origin` branches still shows the old list, and I can&#39;t find anyway to refresh it.

I tried changing to a different repo, the &lt;kbd&gt;F5&lt;/kbd&gt; Refresh on the Team Explorer header, I even closed and reopened VS 2017... *but nothing refreshes the list to match what VSTS portal shows*.

I use visual studio to update all my environments with a certain migration. It had worked fine using the command below.
     
    update-database -Migration initMigrationProduct -c ProductContext -Environment Production

In ef core 2.0 this command has been changed and parameter -Environment has been removed. In the docs it said.

&gt; &quot;With 2.0, you can use the ASPNETCORE_ENVIRONMENT environment variable
&gt; instead.&quot;

 
https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet

I have now tried all kinds of ways but when I run the `update-database` with ef core 2.0 it doesn&#39;t use the `ASPNETCORE_ENVIRONMENT` variable. I tried to set in registry, application properties. 

Please let me know what I need to do to get this working to update different environments?

If I start the application with different `launchsettings` it works but not using the package manager console.

ef core doesn&#39;t use ASPNETCORE_ENVIRONMENT during update-database

With the following code, I get a compile error `C2065 &#39;a&#39;: undeclared identifier` (using visual studio 2017):


	[] {
		auto [a, b] = [] {return std::make_tuple(1, 2); }();
		auto r = [&amp;] {return a; }(); //error C2065
	}();

However, the following code compiles:

	[] {
		int a, b;
		std::tie(a, b) = [] {return std::make_tuple(1, 2); }();
		auto r = [&amp;] {return a; }();
	}();

I thought that the two samples were equivalent. Is it a compiler bug or am I missing something ?
