xUnit should be the default test framework for VS templates
xUnit is a more powerful and extensible test framework. .NET Core, and ASP.NET 5 use it as their default. xUnit also supports all current platforms .NET does, including Xamarin.
The default test framework for the Unit Test projects in VS should change to xUnit.
xUnit.net Test Project template is available on the Visual Studio Code Gallery.
Also, the Create Unit Test wizard supports emitting tests in xUnit.net format (using the xUnit.net Test Extensions package).
Based on the above, I am marking this item declined.

Cannot agree with this... leave it open to people to choose a particular testing framework that suits their needs.
This suggestion to use xUnit is purely subjective.

I think that this is a very bad idea.
Just like xUnit in current state is a bad Test Framework.
How about making it a choice for the user instead. I'm sure xUnit is not everyone go to testing framework.
