IDisposable analyzer

[TonyValenti]

Brief description: A class that implements IDisposable is special because it may represent a resource (potentially unmanaged) that should be freed. As C# is increasingly used to write low-level code, this continually becomes more and more important.

An analyzer should exist that will flag when classes that implement IDisposable are created that:

1. Are not disposed of (either explicitly or via using)
2. (if possible), do not escape the current method (either via return, out, or assignment to a property, or by being passed into a method that would cause it to escape).
3. Offered a fixer that would change var x = new <IDisposable Type> to using var x = new <IDisposable Type>

Additionally, it would be nice if the Visual Studio editor provided some type of unique colorization for variables that are of types that implement IDisposable.

Have you seen CA2000: Dispose objects before losing scope?
