Intellitrace is not available for native or mixed-mode debugging

I just opened an old C project in Visual Studio 2010 and tried to understand Intellitrace. But I get this error message

Intellitrace is not available for native or mixed-mode debugging

I searched a bit on SO and found similar but not yet resolved questions. Do you know what could be the proble开发者_StackOverflow中文版m? Thanks

Just as with Visual Studio 2010, Visual Studio 2012 Ultimate also does not provide Intellitrace for native apps.

In Visual Studio 2012, Intellitrace is available for:

• Visual Basic and Visual C# apps that use the .NET Framework 2.0, 3.0, 3.5, 4.0, or 4.5.
• F# apps
• Windows Store apps supported for events only

It is not available for:

• C++, script, or other languages
• Silverlight, Xbox, or Windows Mobile apps

See http://msdn.microsoft.com/en-us/library/vstudio/dd264915.aspx for more info.

The Intellitrace technology is currently only available on managed projects. Mixed-mode by definition contains native code therefore it is disabled.

Intellitrace only works for managed debugging (eg. C# or vb).
