ASP.Net 5 Beta 8 xproj cannot be opened

Question

I just installed the new release of ASP.Net 5 beta 8. I ran DotNetVersionManager-x64.msi and then WebToolsExtensionsVS14.msi. I tried to open a simple app that worked in beta 7 and it won't load the project with a message

This project is incompatible with the current edition of Visual Studio:

Microsoft Visual Studio Community 2015 Version 14.0.23107.0 D14REL
Microsoft .NET Framework
Version 4.6.00079

I then tried to create a new ASP.Net 5 web project and got this:

The project file 'c:\users\myfolder\documents\visual studio 2015\Projects\WebApplication3\src\WebApplication3\WebApplication3.xproj' cannot be opened.

The project type is not supported by this installation.

I have uninstalled and reinstalled the DotNetVersionManager and WebToolsExtensionsVS14 with the same result.

The easiest way to get started building applications with ASP.NET 5 is to install the latest version of Visual Studio 2015 (including the free Community edition).

1. Install Visual Studio 2015

   Be sure to specify that you want to include the Microsoft Web Developer Tools.

2. Install ASP.NET 5.

   This will install the latest ASP.NET 5 runtime and tooling.

3. Enable the ASP.NET 5 command-line tools. Open a command-prompt and run:

   dnvm upgrade

   This will make the default .NET Execution Environment (DNX) active on the path.

4. On Windows 7 and Windows Server 2008 R2 you will also need to install the Visual C++ Redistributable for Visual Studio 2012 Update 4.

You are all set up and ready to write your first ASP.NET 5 application! Reference...
