Sorry, Rainer, I find it didn't get the Debug info ! I test it by DGui.
Converting debug information... "Debug\dguiTest.exe" not created! Building Debug\dguiTest.exe failed! Project Property → Compiler → Debug → Debug Info The Default item is 'Symbolic(suitable for Mago)'. But I use the vs's item : 'Symbolic(suitable for VS debug engine)' Then get the bad info: Building Debug\dguiTest.exe... Converting debug information... "Debug\dguiTest.exe" not created! Building Debug\dguiTest.exe failed! Where is my Error? Maybe it's the Visual D 's Error? Thank you,I'm waiting for your answer.
