Someone recently asked about using Codes Analysis in Visual Studio 2012. Here is one approach. With a solution loaded in Visual Studio 2012, go to the build menu and pick Run Code Analysis on <project name>.
Once the code analysis results appear, click the thing that looks like a gear and opens the configuration tool.
For managed code mine defaulted to Microsoft Managed Recommended Rules. I think that is great place to start and that is the one I’d use.
The rule set field is a drop down. If you think Microsoft Managed Recommended Rules is too much than I’d suggest Microsoft Managed Minimum Rules.
