A reference to a higher version or incompatible assembly cannot be added to the project

If you face this error message while adding a reference to your project in Visual Studio try the following steps.

  • In File Explorer go to the directory of the DLL you are trying to add as reference.
  • Right Click and select properties
  • Click on UnBlock Button
  • Go to Visual Studio and again try to add the file as reference. Now you shouldn’t see this issue.

Note: I faced the error message “A reference to a higher version or incompatible assembly cannot be added to the project” while trying to add AdMob DLL in to my Windows Phone project.
