Excluding Code Analysis rule in source

Question

In a project I'm working on FxCop shows me lots of (and I mean more than 400) errors on the InitializeComponent() methods generated by the Windows Forms designer. Most of those errors are just the assignment of the Text property of labels.

I'd like to suppress those methods in source, so I copied the suppression code generated by FxCop into AssemblyInfo.cs, but it doesn't work.

This is the attribute that FxCop copied to the clipboard.

[module: SuppressMessage("Microsoft.Globalization",
    "CA1303:DoNotPassLiteralsAsLocalizedParameters",
    Scope = "member",
    Target = "WindowsClient.MainForm.InitializeComponent():System.Void",
    MessageId = "System.Windows.Forms.Control.set_Text(System.String)")]

Anyone knows the correct attribute to suppress this messages?

PS: I'm using Visual Studio 2005, C#, FxCop 1.36 beta.

Answer 1

You've probably got the right code, but you also need to add CODE_ANALYSIS as a precompiler defined symbol in the project properties. I think those SuppressMessage attributes are only left in the compiled binaries if CODE_ANALYSIS is defined.

Answer 2

In FxCop 1.36 there is actually a project option on the "Spelling & Analysis" tab that will supress analysis for any generated code.

If you don't want to turn analysis off for all generated code, you need to make sure that you add a CODE_ANALYSIS symbol to the list of conditional compilation symbols (project properties, Build tab). Without this symbol defined, the SupressMessage attributes will be removed from the compiled code so FxCop won't see them.

The other problem with your SuppressMessage attribute is that you are listing a "Target" of a specific method name (in this case WindowsClient.MainForm.InitializeComponent():System.Void) and listing a specific "Scope". You may want to try removing these; otherwise you should add this SuppressMessage to each instance of the method.

You should also upgrade to the RTM version of FxCop 1.36, the beta will not automatically detect the newer version.
