What technical restrictions might prevent MS from implementing IntelliTrace on VS 2010 64-bit?

Question

I found that IntelliTrace is not supported on Visual Studio 2010 64-bit version.

MS says its because of technical restrictions

Can anyone shed some light on what those restrictions might be?

Thanx.

Answer 1

The problem is likely that the IntelliTrace code is written for 32 bit only right now. You cannot invoke a 32-bit library from a 64-bit executable currently in Windows. There are lots of other applications that have this problem as well. For example: Since windows explorer is 64-bit applications that contribute to the right click menu need to also be 64-bit.

This is likely the same issue here. The library was probably not ported to 64-bit yet making it not possible to call it from the new version of Visual Studio.

Answer 2

I agree with the first answer. VS.NET is still a 32Bit application and to debug a 64Bit application, is surly a technical hurdle. There were also some time constraints to push this out with the release of VS.NET 2010.
