Upgrading to DotNet Core RC2 Preview seems to have broken Visual Studio

Let me start by saying that I’m receiving errors left and right inside Visual Studio since upgrading to the newest version of DotNet Core. I’m going to just post one of the problems here in the hopes that they’re all related and/or can be fixed the same. I’ve tried uninstalling/repairing the packages here (https://www.microsoft.com/net/core#windows) several times, with no luck.

Steps to reproduce

1. Create New Project
2. Select Empty template
3. Get the following error message:

Environment data

dotnet --info output:

Further issues

If it helps any, when I try to load a project from RC1, in the ActivityLog.xml file, I get an error loading ITelemetry or something like that. I also get a failure file generated, which contains the following:

5/19/2016 5:24:26 PM Recoverable System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.ProjectSystem.DotNet.Publish.PublishLoader.<<Initialize>b__13_0>d.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.VisualStudio.Threading.JoinableTask.<JoinAsync>d__76.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.VisualStudio.ProjectSystem.DotNet.Publish.PublishLoader.<Initialize>d__13.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)

at Microsoft.VisualStudio.ProjectSystem.UnconfiguredProjectImpl.AutoLoadMethodStateMachine.<<StartExecution>b__6_0>d.MoveNext()

I do not get this error when creating a new project, as I’ve done above.

I think I have a fix.

I went to the following folder: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft

And deleted the “DotNet” folder and the “Web Tools” folder.

Then I did a repair (from Programs and Features) of “Microsoft .NET Core 1.0.0 RC2 - VS 2015 Tooling Preview 1”.

I’m still testing it, but I’m way further than I was able to get before.
