CodeRush allows you to integrate the CodeRush Diagnostics into Visual Studio to analyze code on the fly.
Background Analysis is a resource-demanding feature. Use it with caution on large solutions.
To see code issues in Visual Studio's Error List:
Open the CodeRush menu and choose the Code Analysis | Configure... menu item to invoke the Code Issues Catalog options page.
Check the Register in VS check boxes for the required analyzers.
Click OK to save the changes and close the Code Issues Catalog page.
Restart Visual Studio.
