Hi,
WPF application works fine, Silverlight aren't.
After contacting the guys from SymbolSource, here is their answer :
"I was still trying to figure this out in the meantime. So a blank Silverlight project that I created loads symbols for Cocktail.SL, but silently skip over calls. It doesn't user the source server to get actual sources, even though symbols get loaded just fine. The same code works from a console project, so only Silverlight seems affected.
This is what I referred to before with "partial trust problems". Indeed, Visual Studio 2012 has a new option under Debugger "Allow source server for patial trust assemblies". After enabling it I was able to step into Cocktail.SL code.
So there seems no other way but to upgrade :)"
Any ETA for a compatible version of Devforce/Cocktail with VS2012 ? :)
