Before ServiceStack.Mvc Depand on ServiceStack，
Why This Release Depand On ServiceStack.Signed ?
Ahh crap I modified the wrong NuGet package, I meant to change the new ServiceStack.Mvc.Signed NuGet package to reference ServiceStack.Signed dependency, but looks like I accidentally changed ServiceStack.Mvc instead. I've reverted it back in this commit.
This change is available from v4.0.49 that's now available on MyGet.
Did your solution still work despite referencing the wrong dependency?
I have download the servicestack.mvc.4.0.48.nupkg to local, then change the file extension to .rar, then modify the file servicestack.mvc.nuspec to right content. After that , modify the file extension back to .nupkg, Now It Can Install NuGet Package From Local.
