Hi Marcia.

>But I finally solved my problem by debugging the code in Visual studio first.

Glad to see you solved the problem, but for the future, just in case you haven't tried this, you can debug C# code called from wwDotNetBridge, a feature I use all the time. In VS, simply choose Attach to Process from the Debug menu and select the VFP instance. You can then set a breakpoint in the C# code and as soon as it's called from wwDotNetBridge, you get debugging in VS.
