C# catch(FileNotFoundException) and CA1031

So this code triggers CA1031

    // logic
catch (FileNotFoundException) // exception type
    // handle error

This occurs because a "general exception such as System.Exception or System.SystemException is caught in a catch statement, or a general catch clause such as catch() is used". To fix it, assign it and handle the error and or rethrow the general exception for it to be handled further up.

Upon further investigation, it seems this used to be an bug, you can see more here; it was a Roslyn issue for FxCop.

To Fix: Just update the latest FxCop analyzers package and it should go way.


 Install-Package Microsoft.CodeAnalysis.FxCopAnalyzers -Version 2.9.7
