[Bibo1978]

after last upgrade to rc1-update2 I am getting this error

Error CS0433 The type 'SecureString' exists in both 'System.Security.SecureString, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' and 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' .DNX 4.5.1.0

I am using

dnvm use 1.0.0-rc1-update1 -r clr -arch x64 -p

Project .json looks like this

},

"exclude": [ "wwwroot", "node_modules" ], "publishExclude": [ ".user", ".vspscc" ] }

no global.json it messed up everything when I try

DNX is no longer supported. I recommend moving to ASP.NET Core RC2 bits with dotnet CLI.
