FAQ: How do I increase the number of Code Analysis warnings displayed in the Error List? [David Kean]
When first running Visual Studio Code Analysis over a large project, you may encounter the following error:
CA0503: Additional warnings cannot be displayed.
By default, a maximum of 200 warnings are displayed in the Error List. You can increase this amount by modifying the following registry value:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Setup\EDev\CodeAnalysisErrorListViolationLimit
Simply set this to a value that suits your needs.
