Symptoms

Consider the following scenario:
  • You have an application that contains many libraries in Microsoft Visual Studio 2010. 
  • You build the project, and more than 2048 program database (PDB) files are generated.
  • You try to debug the application.
In this scenario, Visual Studio 2010 loads only 2048 of the PDB files. Additionally, you receive the following error message in the Output window:
Cannot find or open the PDB file.

Note Performance issues may also occur if an application contains many libraries and Visual Studio 2010 loads all the PDB files when you debug the application.
