I am using [`pytest`][1], and the test execution is supposed to run until it encounters an exception. If the test never encounters an exception it should continue running for the rest of time or until I send it a SIGINT/SIGTERM.

Is there a programmatic way to tell `pytest` to stop running on the first failure as opposed to having to do this at the command line?

I came across some code with a line similar to

    x[x&lt;2]=0
    
Playing around with variations, I am still stuck on what this syntax does.

Examples:

    &gt;&gt;&gt; x = [1,2,3,4,5]
    &gt;&gt;&gt; x[x&lt;2]
    1
    &gt;&gt;&gt; x[x&lt;3]
    1
    &gt;&gt;&gt; x[x&gt;2]
    2
    &gt;&gt;&gt; x[x&lt;2]=0
    &gt;&gt;&gt; x
    [0, 2, 3, 4, 5]


What does x[x &lt; 2] = 0 mean in Python?

This is what I know

    str = String.Format(&quot;Her name is {0} and she&#39;s {1} years old&quot;, &quot;Lisa&quot;, &quot;10&quot;);

But I want something like

    str = String(&quot;Her name is @name and she&#39;s @age years old&quot;);
    str.addParameter(@name, &quot;Lisa&quot;);
    str.addParameter(@age, 10);

Is there a &quot;String.Format&quot; that can accept named input parameters instead of index placeholders?

What is the difference between a property with a omitted setter and a property with a private setter?

    public string Foo { get; private set; }

vs

    public string Foo { get; }


Omitted setter vs private setter?

&gt; java.lang.OutOfMemoryError. Consider increasing the value of

I am getting out of memory exception in my visualstudio Xamarin Project Please help me how can i resolve this issue.

Getting OutOfMemoryException in Xamarin

I have a Service Object `Update` 

    public bool Update(object original, object modified)
    {
        var originalClient = (Client)original;
        var modifiedClient = (Client)modified;
        _context.Clients.Update(originalClient); //&lt;-- throws the error
        _context.SaveChanges();
        //Variance checking and logging of changes between the modified and original
    }

This is where I am calling this method from:

    public IActionResult Update(DetailViewModel vm)
    {
        var originalClient = (Client)_service.GetAsNoTracking(vm.ClientId);
        var modifiedClient = (Client)_service.Fetch(vm.ClientId.ToString());
        // Changing the modifiedClient here
        _service.Update(originalClient, modifiedClient);
    }

Here is the `GetAsNotTracking` method:

    public Client GetAsNoTracking(long id)
    {
        return GetClientQueryableObject(id).AsNoTracking().FirstOrDefault();
    }

`Fetch` method:

    public object Fetch(string id)
    {
       long fetchId;
       long.TryParse(id, out fetchId);
       return GetClientQueryableObject(fetchId).FirstOrDefault();
    }

`GetClientQueryableObject`:

    private Microsoft.Data.Entity.Query.IIncludableQueryable&lt;Client, ActivityType&gt; GetClientQueryableObject(long searchId)
    {
        return _context.Clients
            .Where(x =&gt; x.Id == searchId)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.BusinessUnit)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.Probability)
            .Include(x =&gt; x.Industry)
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.User)
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.ActivityType);
     }

Any ideas?


I have looked the following articles / discussions. To no avail:[ASP.NET GitHub Issue 3839][1]

**UPDATE:**

Here are the changes to `GetAsNoTracking`:

    public Client GetAsNoTracking(long id)
    {
        return GetClientQueryableObjectAsNoTracking(id).FirstOrDefault();
    }

`GetClientQueryableObjectAsNoTracking`:

    private IQueryable&lt;Client&gt; GetClientQueryableObjectAsNoTracking(long searchId)
    {
        return _context.Clients
            .Where(x =&gt; x.Id == searchId)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.BusinessUnit)
            .AsNoTracking()
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.Probability)
            .AsNoTracking()
            .Include(x =&gt; x.Industry)
            .AsNoTracking()
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.User)
            .AsNoTracking()
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.ActivityType)
            .AsNoTracking();
    }

We are working with .NET Core Web Api, and looking for a lightweight solution to log requests with variable intensity into database, but don&#39;t want client&#39;s to wait for the saving process.  
Unfortunately there&#39;s no `HostingEnvironment.QueueBackgroundWorkItem(..)` implemented in `dnx`, and `Task.Run(..)` is not safe.  
Is there any elegant solution?

I have copied my solution file from another system and tried to run it on my machine:
For this, I have gone to the project folder and deleted the previous solution file and copied the new one.

Now, it started giving me error. connection refused etc. So, I got one solution from here: https://stackoverflow.com/questions/32190881/how-to-solve-err-connection-refused-when-trying-to-connect-to-localhost-running

According to it, I changed the port number from 1049 to 1052. It loaded and one of the pages gets loaded.
But when I entered the desired login credentials then it redirected to the older port again, like this:

    http://localhost:1049/Home/SearchFlight

and the error is:

     This site can’t be reached

     localhost refused to connect.
     Search Google for localhost 1049 Home Search Flight
     ERR_CONNECTION_REFUSED

Now, I don&#39;t know what to do from here. I have changed the port number to 1052 but still its pointing to 1049. What should i do now?

I have Visual Studio Ultimate/Enterprise installed from a previous engagement. I&#39;ve now started at a new place who only have licenses form VS Professional. So I need to downgrade but the supported route involves full uninstall and full reinstall which is obviously rather time consuming.

Are there any &quot;clever&quot; (probably unsupported) ways to do the downgrade?

Any quick ways to downgrade Visual Studio Ultimate/Enterprise edition to Professional?

What to use in UWP, `Binding` or `x:Bind` and what is the difference between them?

Because I see a lot of posts where people use `Binding` and I only Bind with `x:Bind` in UWP.

At the MSDN Homepage it only says that &quot;the binding objects created by `{x:Bind}` and `{Binding}` are largely functionally equivalent.&quot; and that `x:Bind` is **faster**. 

**But what is the difference between them?** 

Because &quot;largely functionally equivalent&quot; does not mean equivalent.

The Link from my Quote: [MSDN][1]

**So my Question is:**

What is the difference in using Binding or x:Bind in UWP?

After adding `WindowsRuntime` to a WinForms-project, building the project fails with Error &quot;Must use PackageReference&quot;. The build log is more precise:

&gt;C:\[...]\Visual Studio 2017\Projects\Projectname\packages\Microsoft.Windows.SDK.Contracts.10.0.18362.2005\build\Microsoft.Windows.SDK.Contracts.targets(4,5): error : Must use PackageReference

Here&#39;s what I did:

Install-Package Microsoft.Windows.SDK.Contracts

with references to:

 - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore\v4.5\System.Runtime.WindowsRuntime.dll,
 - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\Facades\System.Runtime.dll
 - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\Facades\System.Threading.Tasks.dll
 - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\Facades\System.IO.dll
 - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\Facades\System.Runtime.InteropServices.WindowsRuntime.dll.

Is it maybe a thing with the .NET version? In the project&#39;s packages.config there is 4.6 while the project targets 4.5.

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;packages&gt;
    &lt;package id=&quot;Microsoft.Windows.SDK.Contracts&quot; version=&quot;10.0.18362.2005&quot; targetFramework=&quot;net45&quot;/&gt;
    &lt;package id=&quot;System.Runtime.WindowsRuntime&quot; version=&quot;4.6.0&quot; targetFramework=&quot;net45&quot; /&gt;
    &lt;package id=&quot;System.Runtime.WindowsRuntime.UI.Xaml&quot; version=&quot;4.6.0&quot; targetFramework=&quot;net45&quot; /&gt;
    &lt;/packages&gt;

There are no compile errors... only this strange &quot;PackageReference&quot; error.
