In my Visual Studio 2010 project I have files with .mm file extension, that need to be compiled as normal C++ files. Is there a way to make a build rule for new extensions or something like that? In VS 2008 there were options for that, but they are gone in 2010.

+2  A: 

You can set how the file will be compiled for any unknown file type by:

  1. Right click on the file in your solution explorer
  2. Click on properties on the file
  3. Go to the General tab
  4. Set exclude from build to: No
  5. Set Item type: to C/C++ compiler

+3  A: 

For an individual file: Right click on the file > Properties > Configuration Properties - General > Item Type : C/C++ compiler.

In general for a project: How to: Select the Files to Build, Walkthrough: Using MSBuild, Walkthrough: Creating an MSBuild Project File from Scratch.
