I have a issue when I tried to start several Robotics Projects as one Robotics Project.

There are many Robtics Projects on my project and I combine them by procedure below.

1.Create AllRun project and set 'Set as StartUp Project'.
2.Select AllRun project on Solution Explorer and execute 'Add Reference' and select other projects.
3.Select AllRun project on Solution Explorer and execute 'Manage Imported projects' and select other projects.

Usually this setting works fine but this time I saw error message when I tried 'Start Debugging'.
The error message shows below.

<Error Message>
Error loadin project.
Invalid project path:
C:\Users\XXXXXX\AppData\Local\OpenSpan\8.0\Projects\Project-XXXXXXXXX\{Project Name A}.dll

So I checked the Project, which displayed on error message, and found Assembly Name and Default Namesapce are different with other projects.

Usually Assembly Name and Default Namespace are same with name fo Robotics Project,
but the Assembly Name and Default Namesapce of project , which displayed on error message, has extension of ".osproj".
And the dll file of the project also include ".osproj" extension, like "SampleRobot.osproj.dll".
(Dll file of other project doesn't inclue ".osproj" extension, like "SampleRobot.dll".)

How can I change it's dll name not to include ".osproj" extension?

This project doesn't show any error when I 'Start Debugging' as single project but shows error when I include this project to other project.
