Source Analysis for C# does for C# code what Microsoft Word's grammar check does for your documents. Even though your code will work the same and your sentence will project the same idea, Source Analysis standardizes the way you write code or fixes your grammar.
If you write code with multiple other developers and would like to standardize on commenting, variable names, and many other items, Source Analysis helps you do that with 200+ rules for formatting your code.
This helps to make your code more readable, which is a bonus if a few months down the road you need to modify something you or a co-worker wrote.
I installed this right away and updated my current project. I suggest you do the same.
I'm not going to reinvent the wheel with this post, so if you want to read more about Source Analysis for C# there are many blog posts.
