Debug information (symbols) could not be found for target assembly 'AssemblyName'. For best analysis results, include the .pdb file with debug information for 'AssemblyName' in the same directory as the target assembly.
The debug information found in .pdb files improves the accuracy of some Code Analysis checks. A missing .pdb file can lead to increased false positives. To enable .pdb generation, open the project properties page. On the Build tab, find the Debug Info list. The location varies by project type. Make sure that Debug info is either set to full for debug builds or to pdb-only for release builds. It should not be set to none.
