Writing to Output window from a c++ called by C#

Question

I have a solution that is mostly C#, but has also few C++ projects.
At some point I call a c++ dll from C# code.

Is there a way to write to visual studio output window from the c++ code (for debugging purposes)? I tried printf but it did not seem to have any effect...

(I am using VS 2012, .Net 4.5)

You can use the OutputDebugString function.

If you want to support variable arguments (like printf), you need to add a bit more code as in this answer: How do you create a debug only function that takes a variable argument list? Like printf()
