DNX Error when running webapplication, ideas?

Question

i just installed a new empty ASP.NET 5 WebApplication and got this error when running the app via IISExpress. Any idea what the problem is?

Answer 1

You declare dependencies on beta6 but use dnx beta7, you should update your dependencies to last stable release 1.0.0-rc1-update1 and use it.

Set also the alias default on 1.0.0-rc1-update1:

dnvm commands

 dnvm alias default 1.0.0-rc1-update1 -a x86 -r clr

 dnvm use default

Microsoft.AspNet.Server.IIS doesn't exist for rc1, replace it by Microsoft.AspNet.IISPlatformHandler

project.json

"dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-rc1-final"
},

You might also uninstall old beta versions and update dnvm to the latest stable version.
