I'm having a major issue recording on a dotnet Windows Forms app. VUGen does not seem to record all the function calls and it calls functions which itself it does not recognise and thus gives error messages.
I understand this is an issue with setting the ilters correctly. I'm very new to the application under test and to dotnet.
Is there some addin to LR fo dotnet which will help record the correct calls. Or is there another external profiler of some sort which will generate the calls correctly and I can use it as a reference while recording with vugen.
