I am have problem with Debugging API under C# (Framework 2.0). A am run Debugged process as follows:

int size;
GetCORVersion(null, 0, out size);
Debug.Assert(size > 0);
StringBuilder sb = new StringBuilder(size);
int hr = GetCORVersion(sb, sb.Capacity, out size);

CreateDebuggingInterfaceFromVersion(3, sb.ToString(), out m_ICorDebug);
Debug.Assert(m_ICorDebug != null);

m_ICorDebug.Initialize();
CManagedCallback _mc = new CManagedCallback(this);
m_ICorDebug.SetManagedHandler(_mc);

PROCESS_INFORMATION pi = new PROCESS_INFORMATION();

STARTUPINFO si = new STARTUPINFO();
si.cb = Marshal.SizeOf(si);

// initialize safe handles
si.hStdInput = new Microsoft.Win32.SafeHandles.SafeFileHandle(new IntPtr(0), false);
si.hStdOutput = new Microsoft.Win32.SafeHandles.SafeFileHandle(new IntPtr(0), false);
si.hStdError = new Microsoft.Win32.SafeHandles.SafeFileHandle(new IntPtr(0), false);

//constrained execution region (CER)
System.Runtime.CompilerServices.RuntimeHelpers.PrepareConstrainedRegions();
string commandLine = "WindowsApplication1.exe";
string applicationName = null;
int flags = 0;
string currentDirectory = ".";
IntPtr environment = new IntPtr(0);

m_ICorDebug.CreateProcess(
applicationName,
commandLine,
null,
null,
1,
(uint)flags,
environment,
currentDirectory,
si,
pi,
CorDebugCreateProcessFlags.DEBUG_NO_SPECIAL_OPTIONS,
out m_ICorDebugProcess);

CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);

But one function of a class (CManagedCallbck : ICorDebugManagedCallback) is not callback.
In what a problem?

Best regards

Hello Aniskevich,
from your code snippet I cannot determine why is your code not working.
Generally it is possible to write a debugger in managed code.
We have a complete sample of managed debugger written in C#, feel free to
refer to it for your needs,
The sample is located at:

Thanks for your answer.
I studied before your example
(http://www.microsoft.com/downloads/details.aspx?familyid=38449a42-6b7a-4e28-80ce-c55645ab1310&displaylang=en),
however it very complex and I has got confused.

If it is possible, send, please, the simple example in which occurs
creation ICorDebug, ICorDebugManagedCallback and calling method
CreateProcess.

Beforehand thanks.

Hello Aniskevich,
I understand the reading (and also writing) debugger code is non-trivial.
The API is pretty complicated. On the other hand you
need to expect non-trivial API for anything that is doing so powerfull
operation as enabling debugging.

I recommend you studying code in the corapi\debug directory first in the
sample. Also, please refer to CorDebug.idl header file that describes
what individual API do.

If you want to learn more about the debugger, and would like to get to some
more simplistic code, I would recommand, that you start with
the mentioned sample and keep removing parts that you don't need.
