Debugging and Profiling Applications
To debug a .NET Framework application, the compiler and runtime environment must be configured to enable a debugger to attach to the application and to produce both symbols and line maps, if possible, for the application and its corresponding Microsoft intermediate language (MSIL). Once a managed application is debugged, it can be profiled to boost performance. Profiling evaluates and describes the lines of source code that generate the most frequently executed code, and how much time it takes to execute them.
.NET Framework applications are easily debugged using Visual Studio, which handles many of the configuration details. If Visual Studio is not installed, you can examine and improve the performance of .NET Framework applications in several alternative ways, by using the following:
The .NET Framework namespace System.Diagnostics includes the Trace, Debug, and TraceSource classes for tracing execution flow, and the Process, EventLog, and PerformanceCounter classes for profiling code. The Cordbg.exe command-line debugger can be used to debug managed code from the command-line interpreter.
