When you have deployed a .NET target, you can debug it in the PowerBuilder debugger. Invoke the debugger by clicking the Debug icon in the toolbar in the Project painter, or by right-clicking on the project in the System Tree and selecting the Debug menu item. If a Windows Forms application is already running, you can attach the debugger to the running process.
The debugger has almost the same operations for .NET targets as for standard PowerBuilder targets. Most PowerBuilder debugging features, including expression evaluation and conditional breakpoints, are supported in .NET applications. The Objects in Memory view and variable breakpoints are not supported due to limitations of the .NET platform. In both .NET and standard applications, you can break into the debugger when an exception is thrown (see “Breaking into the debugger when an exception is thrown”).
