You could also run a MATLAB session as usual, and then attach Visual Studio to the running process. This is explained in more details in the documentation. Here is a quick summary:

• compile the source MEX-file with debugging symbols enabled.

• start a normal MATLAB session. Then from Visual Studio, attach to the running matlab.exe process.
• finally from MATLAB, run the MEX-function. You should hit the breakpoint with execution paused.
