How to start a child process in the same Visual Studio debugging session as the parent, programmatically?

Question

When running a process under the debugger, I would like to start a child process in the same debugger.

Currently, I use

Process.Start(\"sample.exe\")

You should attach debugger to process you are starting. This could be done:

1. Manually from Visual Studio after starting "sample.exe" select it menu Debug > Attach to process..
2. Programmatically attach debugger inside "sample.exe"
3. Attaching to a Process using VS.NET Automation Model
4. UPDATE: You can setup windows environment to attach debugger every time "sample.exe" starts: Launch the Debugger Automatically (you will need to call Debugger.Break anyway)
5. Some external tool maybe

Here is code for "sample.exe" to attach debugger:

if (!Debugger.IsAttached)
     Debugger.Launch();
Debugger.Break();

You should pass some parameter to "sample.exe" to verify if you need to attach debugger.

Process.Start("sample.exe", "Debug=true");
