ASP.NET VNEXT DNU Restore error

Every time I try to perform a package restore in visual studio, I get the error below. I also get the same error when using the samples from github with the command prompt i.e (

C:\Users\xxxxxx\Documents\GitHub\aspnet\samples\1.0.0-beta4\HelloMvc dnu restore)

I set my execution environment to use the following dnx -dnvm use 1.0.0-beta4 -r clr -arch x86 -p

I have tried deleting the packages from .dnx/packages and have tried replacing the runtimes, but nothing seems to work.

This may be a result of installing visual studio 2015 RC over the CTP 6; however, I have tried uninstalling and re-installing visual studio multiple times.

Any help would be appreciated.

Found the issue: Newtonsoft.json.dll verion 6.0.3 does not contain the CreateNull method. Added version 6.0.8 to the GAC and everything worked.
