I am using Visual Studio 2015 Community Edition and have upgraded my existing ASP.NET MVC6 application to beta. Now I can no longer open the project. Visual Studio crashes with the following Exception:
08.09.2015 20:23:12
Crippling

Google for the error message The specified content type by default (default) is not defined in the project item schema. did not bring any useful hint. At first I thought it had something to do with dnvm. So this is my result dnvm list:
Active Version Runtime Architecture OperatingSystem Alias

My global.json looks like this:
{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-beta7"
}
}
Removing the sdk part does not change anything.
