If you are a C# developer like me, i think you will like this tool ! StyleCop is an open source (yes, it is FREE!) static code analysis tool from Microsoft that checks C# code for conformance to StyleCop’s recommended coding styles and a subset of Microsoft’s .NET Framework Design Guidelines, find out more here.
In my working environment, I use this tool to scan my code every time before i check in the code to source control to maintain code consistency. You can download this free tool from Stylecop.
