Debug COM DLL from ASP.Net

[Member 7411422]

Hi, I want to debug COM dll solution through another ASP.Net solution (IIS). Solution A - COM dll which outputs 4 com dll's. Solution B - ASP.Net which access, solution A COM dll's. This solution was hosted in IIS Solution B I able to debug through Visualstudio->Debug->attachtoprocess->w3wp.exe But when solution B calls COM dll which is from solution A , I cannot debug Solution A(COM Dll). Please suggest solution for debugging. (Usually I debug the dll solution through VS->Project->properties->Debugging->command->setting target exe path. But here it is asp.net solution, so I don't know what to give in Target exe path)
