CC 7.0.7 - c# .Net Project not runable

Hi together,

if I choose the "CLR_Phone.dll" from SAP CC 7.0.7 installation I can compile my test-project but with running it I get a "BadImageFormatException" in Program.cs at step "Application.Run(new Form1())".

I am using .Net Framework 4.0

I have no problems using the C:\Programm File (x86)\SAP\BCM\Terminal\BCM_CLR_Phone.dll with my .Net 4.0 Project.

Is there anybody else having this issue?

Thanks,

Robert
