How to Pass Parameters to FxCop from Visual Studio - OR - How to Fix the Dreaded CA0060 Warning
If you've enabled FxCop to run on your projects in Visual Studio, chances are you've seen the dreaded CA0060 warning:
MSBUILD : warning : CA0060 : The indirectly-referenced assembly 'SomeAssembly, Version=188.8.131.52, Culture=neutral, PublicKeyToken=abcdef1234567890' could not be found. This assembly is not required for analysis, however, analysis results could be incomplete. This assembly was referenced by: C:\Path\To\Some\Dependency.dll.
The MSDN docs on this warning say that you should just add a reference to the indirectly referenced assembly so FxCop can find it. The problem is, if you already have a reference to a later version of the indirect dependency, you can't really reference both versions.
I found a forum
that explains that you can change the behavior of FxCop to allow
resolution of dependency assemblies to look at the strong name info but
ignore the version. You do that by adding the following to
FxCopCmd.exe.config in the
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop
<add key="AssemblyReferenceResolveMode" value="StrongNameIgnoringVersion" />
Of course, if you do that, it affects every single solution on your machine. Plus, you have to tell every developer on your team to make the same change, and... ugh. No.
A little Reflectoring shows that you can actually specify a lot more
on the command line than running
FxCopCmd /? says you can. Here are
the ones I found that don't show up:
assemblycomparemode one is what ties to the
AssemblyResolveReferenceMode value from
fact, you can pass this value in on the command line if you were running
FxCopCmd.exe /assemblycomparemode:StrongNameIgnoringVersion [and the rest of your parameters]
Except, you're running from inside Visual Studio, so you don't have access to the command line... *or do you?*
Poking through the
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\CodeAnalysis\Microsoft.CodeAnalysis.Targets
file that gets installed with Visual Studio (and is what runs FxCop), it
turns out that if you provide a property called
$(CodeAnalysisAdditionalOptions) with the list of additional command
line options you want for FxCop, they'll be passed in. You just have
to do a little manual .csproj hacking to add the property.
<?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <!-- This is the first PropertyGroup in your project. --> <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration> <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform> <!-- ...and all the other stuff, then before the group end: --> <CodeAnalysisAdditionalOptions>/assemblycomparemode:StrongNameIgnoringVersion</CodeAnalysisAdditionalOptions> </PropertyGroup> <!-- ...and then the rest of your project file. --> </Project>
Now when FxCop runs, that command line parameter list will be passed in along with everything else and the CA0060 warning will go away. Plus, the setting is transported along with the individual project, so it doesn't affect your installed config files and you don't have to get any developers to do anything to their machines. Done!
