Error with new AutoId attribute

I have taken the latest MyGet package and now am unable to log into my application. I have a custom endpoint, with the a manual call to the auth service, with code like:

var authResponse = authService.Post(
				new Authenticate
					provider = CredentialsAuthProvider.Name,
					UserName = request.UserName, //?? request.Email,
					Password = request.Password,
					Continue = request.Continue,

and that causes a failure with error:

System.TypeLoadException: 'Could not load type 'ServiceStack.DataAnnotations.AutoIdAttribute' from assembly 'ServiceStack.Interfaces, Version=, Culture=neutral, PublicKeyToken=null'.'

I have cleaned nuget cache within VS, shut down vs, dont a clear all locals, reopened VS, dotnet restore, same issue. Additionally, i happen to be installing a new , totalyl fresh machine, in which i see the same issue, and I notice that the attribute was newly added last night. I’m a bit confused by the error message, and having trouble fixing this.

I’ve rebuilt all the CI packages so the latest v5.0.3 on MyGet should have all dependencies in sync, which you can download after clearing your NuGet packages cache:

$ nuget locals all -clear
