Where to Store Break Point In .NET framwork

In .NET — nowhere. .NET Framework has nothing to do with breakpoints. A concrete set of breakpoints and their states is related to development process only and its persistence can be proprietary to development tools.

I just checked up my guess about where breakpoints are stored by Visual Studio. A simple experiment confirmed my guess: the breakpoints are attributed to the state of a solution (and not a project) and are stored in the .suo file. This file should not be considered as a part of source code. This is a temporary file used to persist solution state during development; it should not be published, put to the code base using Revision Control system, preserved when a solution is moved to a different location, etc. Doing so is a common mistake.

[EDIT]
What is related to .NET Framework is the support of debugging in the .NET application using the class System.Diagnostics.Debugger, http://msdn.microsoft.com/en-us/library/system.diagnostics.debugger.aspx[^]. This is something different from the breakpoints you mean, but is important part of .NET functionality. I appreciate the post by Simon where he pointed it out.

While Jürgen and SA are correct, I suppose you could say you stored a breakpoint in you assembly if you were to use Debugger.Break[^]

However get the feeling that you do not speak of breakpoints used for debugging, but something else, perhaps how to log information about where your application crashed and burned, just guessing here :)

If you do not talk about debug breakpoints, you need to update your question so you more clearly state what you want, perhaps some examples of what you want to do might help.
