Debugging Run-Time Logic
Enhancing your code with aspects gives you a new dimension to your debugging experience. With PostSharp, patterns are implemented in classes that are separate from the business logic. Most of the time, you will want to debug just the business logic. But sometimes, you will want to debug the aspects: aspect code will now be skipped by default during step-into sessions and in the call stack window.
This topic contains the following sections:
Suppose you have a SayHello method intercepted by an Intercept aspect. You are about to step into the SayHello method. By default, the debugger steps over the code of the Intercept aspect and then breaks in the beginning of the SayHello method. When Step Into Aspects is enabled, the debugger will step into the Intercept aspect.
The Step Into Aspects feature is disabled by default. To turn it on, go to the menu PostSharp / Options, then to the General tab and the Debugging section, and check the Step Into Aspects check box. Now you can step into aspects using the Step Into (F11) command of the debugger.
By default, all the calls to the methods of the Intercept aspect are hidden behind one stack frame named [Aspect Code]. Suppose you have the SayHello method intercepted by the Intercept aspect like in the example above. You are inside the SayHello method. In the call stack, all the methods introduced by PostSharp are hidden.
Sometimes you may need to see the real call stack that includes all intermediate method calls generated by PostSharp. This is the purpose of the Show Aspects Code in Call Stack feature.
To turn it on, go to the menu PostSharp / Options, then to the General tab and the Debugging section, and check the Show Aspects Code in Call Stack check box. Now, the call stack includes all the methods introduced by PostSharp.
PostSharp improves your debugging experience by installing extensions for the Visual Studio Debugger and by enhancing PDB files during the build. In some use cases you may want to disable these PostSharp debugger extensions and revert back to the default debugging behavior in Visual Studio (e.g. building for a new or unsupported target framework, debugging code on unsupported devices, working around bugs, etc.).
To disable PostSharp debugger extensions:
Right-click on your solution in the Solution Explorer and then click Properties
On the PostSharp page of the displayed solution property pages dialog, select the check box Disable debugging experience improvements.
Confirm the change by clicking OK and then rebuild your solution.
Debugging extensions are automatically disabled when you build your project using MSBuild from outside Visual Studio.
If you build a solution with debugging extensions enabled, you must debug the solution with an instance of Visual Studio where debugging extensions are enabled, otherwise your debugging experience will be frustrating.
