How to start an extension project in visual studio to capture Debug.Start and Debug.StartWithoutDebugging events

[Ncerna]

write visual studio extension how to capture Debug.Start and Debug.StartWithoutDebugging events..someone help me create a simple project to get started thanks

[RobertvanderHulst]

What I did is this:

• create a class that implements IVsDebuggerEvents
• get the debugger object with the help from the VS class inside the toolkit (must be done on the main thread)

await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync();
m_debugger = await VS.GetServiceAsync<SVsShellDebugger,IVsDebugger>();
Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(hr);

• register the class as event handler
  hr = m_debugger.AdviseDebuggerEvents(this, out m_Debuggercookie);

• get the initial value of the debugger 'state'

DBGMODE[] modeArray = new DBGMODE[1];
hr = m_debugger.GetMode(modeArray);

• The event handler looks like this

public int OnModeChange(DBGMODE dbgmodeNew)
{
   XSettings.DebuggerMode = (DebuggerMode)dbgmodeNew;
   return VSConstants.S_OK;
}

DebuggerMode is an enum in the toolkit with the values:

public enum DebuggerMode
    {
        Design = 0,
        Break = 1,
        Running = 2,
        EditAndContinue = 0x10000000,
        EditAndContinueMask = -268435457
    }

Don't forget to unregister the event handler when you no longer need it

await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync();
if (m_debugger != null && m_Debuggercookie != 0)
{
    hr = m_debugger.UnadviseDebuggerEvents(m_Debuggercookie);
    Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(hr);
}

to implement class IVsDebuggerEvents which kind of project I create from QUI..

[RobertvanderHulst]

You create a package. Inside the package, you register the event handler.
Or you download the source code for the Community Toolkit. There is a sample project in there.
You could try to add the debugger monitoring to the example

[Ncerna]

a favor and how do I initialize the package or the event to start capturing.

[Ncerna]

class that implements IVsDebuggerEvents , please give me a hand to be able to initialize

[RobertvanderHulst]

I would recommend creating an object of this class from within the InitializeAsync() that you already have in your package.
Did you also add the OnModeChange() event method.
And I would not use a discard variable (_) for the cookie. You are supposed to store that cookie, so you can use that cookie to unregister the event handler when needed.

I got it, thank you very much for your help...🤝

I want to write an extension for visual studio that captures the metrics (time, size and defect) of the Personal Software Process (PSP) as I would start... thanks a lot in advance ..
