Just a reminder beta 8 for ASP .NET is out:

http://www.microsoft.com/en-us/download/confirmation.aspx?id=49442

If you don’t install this tooling, you will get an error (see below), when manual upgrading from beta 5 to 8 in the project.json file.

Don’t forget to set the Solution DNX SDK version of your project to 1.0.0-beta8.

Also make sure you set the default document, when using only static files and target the .NET Core runtime.
