How to generate flow diagram from ASP.Net and C#.Net code?

Question

I have started working on a new project and the code is huge. Documentation for that project is out of date. But i need to understand the code. One way is that i can put break point and debug the code to understand it but since code is huge and it may take about a month to understand in that way. What else or other faster approach i can use to understand the code something like creating its flow diagram from code?

If you're lucky enough to be using VS 2010 Ultimate then you can generate sequence diagrams simply by right-clicking a method and choosing "Generate Sequence Diagram...", there is a post here with an example.

You'll need Ultimate because you need UML support which is only in Ultimate edition.
