strange, if releated to Newtonsoft.Json.. if I remove the ref, it builds, but add it back (via packages\Newtonsoft.Json.5.0.8\lib\net40) I get same build error?
I bet you are targeting .Net 4.0 framework? What if you switch to 4.5 just to test compile time..
Yep, I Was targeting 4.0.. updated to 4.5.. I had to update some NuGet packages, but all is well now.
I've been having some issues with references in my project, but I am now getting the following compile error, and can't seem to resolve it.. any one seen this before?
Error 12 Missing compiler required member 'System.Runtime.CompilerServices.ExtensionAttribute..ctor' E:\Sites\EPiServer\MYSITE.Web\wwwroot\CSC MYSITE.Web
