Microsoft Project Prof. 2010 Client with ProjectServer Connection

Hello everybody,

I have problems with my project client instance (Microsoft.Office.Interop.MSProject.Application).
It does not have a connection to my project server.

In the project client itself, i have a default connection to my Project Server. The instance in my program is not using the this default connection.

I instantiate with following code:

var projApp = new Microsoft.Office.Interop.MSProject.Application();

Could somebody help me, how to get a Project Server Connection.

Thanks in advance.

Best regards.

Marc
