The problem for me was that the checkbox &quot;Signing the ClickOnce manifest&quot; was checked. If you are not using signing uncheck it in 
Project Properties-&gt;signing-&gt;sign the clickonce manifests

Unchecking the &quot;Signing the ClientOnce Manifest&quot; doesn&#39;t always work. The solution is to remove the following lines from your csproj files

&gt; &amp;lt;PropertyGroup&amp;gt;
&amp;lt;ManifestCertificateThumbprint&amp;gt;4FCE3F0998F4B89946A9D0346838E77A0C5C5568&amp;lt;/ManifestCertificateThumbprint&amp;gt;
&amp;lt;/PropertyGroup&amp;gt;
&amp;lt;PropertyGroup&amp;gt;
&amp;lt;GenerateManifests&amp;gt;true&amp;lt;/GenerateManifests&amp;gt;
&amp;lt;/PropertyGroup&amp;gt;
&amp;lt;PropertyGroup&amp;gt;
&amp;lt;SignManifests&amp;gt;false&amp;lt;/SignManifests&amp;gt;
&amp;lt;/PropertyGroup&amp;gt;

Given an input of, for example,

    day = &#39;Monday&#39;

how can I calculate the date of the next `day`?


    def date_of_next(day)
      ...
    end

I&#39;m getting a date/time in json as `2011-10-26T20:29:59-07:00`. What&#39;s the proper way to use `gsonBuilder.setDateFormat` to properly format this time?

I signed the assembly with my VSTO 4.0 word add-in with strong name key file `.snk` and tried to uncheck Sign the ClickOnce manifest but after rebuild it appears again. After I tried to delete lines for ClickOnce manifest in `.csproj`, `.pfx` manifest appears after every rebuild.

Does anyone know solution to permanently delete temporary ClickOnce manifest?

I want to make the following `curl` call in my C# console application:

&lt;!-- language-all: lang-sh --&gt;

    curl -d &quot;text=This is a block of text&quot; \
        http://api.repustate.com/v2/demokey/score.json

I tried to do like the question posted [here][1], but I cannot fill the properties properly.

I also tried to convert it to a regular HTTP request:

&lt;!-- language: lang-none --&gt;

    http://api.repustate.com/v2/demokey/score.json?text=&quot;This%20is%20a%20block%20of%20text&quot;

Can I convert a cURL call to an HTTP request?  If so, how?  If not, how can I make the above cURL call from my C# console application properly?

I&#39;m testing out some WCF services that send objects with Guids back and forth. In my web app test code, I&#39;m doing the following:


    var responseObject = proxy.CallService(new RequestObject
    {
        Data = &quot;misc. data&quot;,
        Guid = new Guid()
    });

For some reason, the call to **new Guid()** is generating Guids with all 0&#39;s (zeros) like this:

`00000000-0000-0000-0000-000000000000`

What could be causing this?

Guid is all 0&#39;s (zeros)?

I want to read a text file line by line. I wanted to know if I&#39;m doing it as efficiently as possible within the .NET C# scope of things.

This is what I&#39;m trying so far:

    var filestream = new System.IO.FileStream(textFilePath,
                                              System.IO.FileMode.Open,
                                              System.IO.FileAccess.Read,
                                              System.IO.FileShare.ReadWrite);
    var file = new System.IO.StreamReader(filestream, System.Text.Encoding.UTF8, true, 128);

    while ((lineOfText = file.ReadLine()) != null)
    {
        //Do something with the lineOfText
    }


What&#39;s the fastest way to read a text file line-by-line?

Does anyone stick to any rules (or are you forced to stick to any rules by your employer?) when choosing to use either LINQ query syntax or a Lambda expression inside one of the LINQ extension methods? This applies to any Entities, SQL, objects, anything.

At our workplace, my boss doesn&#39;t like lambda at all and he&#39;d use the query syntax for anything, which in some cases, I find are less readable.

    var names = collection.Select(item =&gt; item.Name);

    var names = from item in collection
                select item.Name;

Maybe when adding a condition, the Lambda I find gets a little messy, where the 

    var names = collection.Where(item =&gt; item.Name == &quot;Fred&quot;)
                          .Select(item =&gt; item.Name);

    var names = from item in collection
                where item.Name == &quot;Fred&quot;
                select item.Name;
    
Just out of interest: how does the compiler treat this one? Does anyone know how the above LINQ query will compile into lambda? Will the `Name` property be called for each element? Could we do this instead and potentially improve the performance? Would this mean lambda is slightly more controllable in terms of performance?

    var names = collection.Select(item =&gt; item.Name)
                          .Where(name =&gt; name == &quot;Fred&quot;);

Certainly when we start using more and more expressions, the lambda gets messy and I&#39;d start to use the query syntax here.

    var names = collection.Where(item =&gt; item.Name == &quot;Fred&quot;)
                          .OrderBy(item =&gt; item.Age)
                          .Select(item =&gt; item.Name);

    var names = from item in collection
                where item.Name == &quot;Fred&quot;
                order by item.Age
                select item.Name;

There are also a few things that I find can&#39;t be done with the query syntax. Some of them you&#39;d think would be really simple (particularly aggregate functions), but no, you have to add one of the LINQ extension methods to the end, which imo, look neater with a lambda expression.

    var names = collection.Count(item =&gt; item.Name == &quot;Fred&quot;);

    var names = (from item in collection
                where item.Name == &quot;Fred&quot;
                select item).Count()

Even for some of the simple lambda chains, [ReSharper][1] is suggesting I convert them to LINQ querys.

Can anyone else add to this? Does anyone have their own little rules or does their company suggest/force the use of one?

I had developed a system that deals with excel sheets in 2006 using MS VS 2005. Now, I can not  use the same reference with MS VS 2012.

Whenever we do a build in our main solution we receive the following warning:

&gt; Unable to apply publish properties for item
&gt; &quot;microsoft.visualstudio.qualitytools.unittestframework&quot;.

Has anyone seen anything like this before? Any ideas on how to fix this? It happens on all of our developer machines and also on our TFS build server as well. However, it only appears in Debug mode.






Unable to apply publish properties for item X

I have to make a backup of the program running from the file [*.appref-ms][1]&lt;br&gt;
When I opened the file [GitHub.appref-ms][1] using a text editor I found
&gt; http://github-windows.s3.amazonaws.com/GitHub.application#GitHub.application, Culture=neutral, PublicKeyToken=8f45a2159c87c850, processorArchitecture=x86 &lt;br&gt;


Where is the target stored on the local disk?&lt;br&gt; 
Editing the **PublicKeyToken** resulted in Default or Null Icon.&lt;br&gt;
Editing the **URL** resulted in &quot;Application Cannot Start&quot;.&lt;br&gt;
How is *.appref-ms targeting the Exe?&lt;br&gt; 
[This doesn&#39;t answer my Question][2]

Note: I tried opening the file offline, it still works perfectly.

How to find the Target *.exe file of *.appref-ms

So I was writing an application that requires access to the registry.
I had not touched any build settings, wanting to get the thing working before I added the other touches, such as a description or name.&lt;br /&gt;&lt;br /&gt;
Out of the blue, I get an error that will not go away. `ClickOnce does not support the request execution level &#39;requireAdministrator&#39;.` Now, I hadn&#39;t touched ClickOnce in this application. All I had done was include a manifest file requesting these permissions.&lt;br /&gt;&lt;br /&gt;
My problem now is that this error will not go away, and I cannot compile my program. Any advice on what to do? (Side note: I am about to go to bed, so I will check this tomorrow afternoon).

&quot;ClickOnce does not support the request execution level &#39;requireAdministrator.&#39;&quot;

With ClickOnce applications, is it possible to replace the current files or install in a different directory when creating a new version? Because the error I get is:

&gt; Unable to install this application because an application with the
&gt; same identity is already installed. To install this application,
&gt; either modify the manifest version for this application or uninstall
&gt; the preexisting application.


ClickOnce application replace current installed fliles

I maintain a large WPF application which I inherited from another developer. I use ClickOnce to publish it. Suddenly, today I got an error message:
Error	2	Cannot publish because a project failed to build.		1	1	
Error	3	An error occurred while signing: Failed to sign bin\Debug\app.publish\\setup.exe. SignTool Error: No certificates were found that met all the given criteria.	

I do have a file called SomeName.snk, which is referred in project settings, Signing tab. I have no idea what happened today that caused the problem.
I use VS 2012.
