Note

No warning is shown when the UnreachableException is thrown.

Current Limitations

• Only direct throw expressions and statements are checked. Exceptions thrown by called methods are not checked.
• The Dispose(false) code path is checked regardless it called by the finalizer.

💡 The analyzer can be deactivated in the ReSharper Options dialog.
