As I am developing .NET application.
one of my client challenge me that WHY our company not use "JAVA" ?
My boss need me to list out what is the advantage of .NET and How it can affect the cost in office ??
e.g Java didn't need license fee ? .NET (if using MSDE, the database is free)
PDF work very well with .NET ??

I really don't know how to do it.
Please give me a help
