Hi,
I created a custom test type in Visual Studio 2010. It works very well in visual studio 2010. And one of the calss inherits the Microsoft.VisualStudio.TestTools.EditorFactory. The VS package which implement the custome test type refer the assembly Microsoft.VisualStudio.ServiceModel.VisualStudioPackage, Microsoft.VisualStudio.ServiceModel, Version=10.0.0.0
Now I deploy the VS package into Visual Studio 2012. I found the Visual Studio 2012 cannot load the package. The error message says: Method 'CreateEditor' in type 'XXXX.TestStepEditorFactory' from assembly 'MMM.NNN, Version=UUUU, Culture=neutral, PublicKeyToken=null' does not have an implementation.
Does anyone see the similar issue or do you have any suggestions for this?
