is it a callback from DLL so can you try this: In project 1 or 2: public delegate void MyDelegate(string delegatestatus); public void somework(string p MyDelegate mydelegatecallback) { callback(mystatus); } In project 3: public void MyProjectcall(string delegatestatus) { // do your work here. } And when you call the method: ProjectB.somework(parametervalue MyProjectcall);
