File templates broken???

I have defined some file templates for diferent type of c# classes. With 9.2 EAP1 somethings seems to be broken in Visual Studio 2015 RC. I select my template, enter a class name and then a message box from Visual Studio appears with the message "The operation could not be completed. Not implemented". Nevertheless the class was generated and the source is shown in the editor. But when i press Tab or Enter the cursor always jumps to the constructor declaration and nothing else happens. Even save the file, close it and open it again doesn't help. I have to delete the file and create it again with the standard VS templates to be able to enter my code in the file. I have created an issue for this in YouTrack.
