Recreate steps:

1. Instantiate a fresh Azure Visual Studio Ultimate 2015 CTP 6 instance.
2. Connect via RDP.
3. Open CMD
4. Run: @powershell -NoProfile -ExecutionPolicy unrestricted -Command "&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}"
5. Run: dnvm upgrade
6. Install Git Hub for Windows, fork & clone https://github.com/aspnet/Home
7. In CMD, change to samples/HelloMVC or samples/HellowWeb
8. Run: dnu restore
9. Run: dnx . web

Environment:

Azure Visual Studio Ultimate 2015 CTP 6 instance
Windows Server 2012 R2
.Net Framework release 393326 (per registry)

Details:

I can run the ConsoleApp. I cannot run HelloWeb or HelloMVC, both return the same error.

After getting the error, I ran set DNX_TRACE=1 to provide more details for the following screenshot:

In your project.json frameworks section, change:

aspnet50 -> dnx451
aspnetcore50 -> dnxcore50

After making the suggested changes I encountered new exceptions (Could not load file or assembly 'IConfiguration').

I did further research and determined that I had cloned the master branch and not dev. Dev worked as documented.

Should the README be updated?

ran into this same issue. after making the change suggested by @davidfowl I get the same IConfiguration error message as @SteveArr. I'm on OSX (10.10.3), dnx (1.0.0-beta4-11566) dnvm (1.0.0-beta5-10375). Same issue as #310
