I completely don't understand the question.
If you have good reasons for not wanting to go with .NET, you have no need to be asking us for reasons.
If, on the other hand, you don't have good reasons, then what's the point?

> The biggest advantage that outweighs them all, do you and your team have more experience in the Java stack or the .NET stack. Push harder for that stack because it will be cheaper for the client if you don’t have to learn a new stack. <- is your company / team capable of writing .NET software today, or would a reschooling be in order ?
To which the OP replied:

So the OP is looking for reasons, and the OP isn't best qualified to offer reasons not to use .NET because of lack of familiarity with .NET. This is why the OP is asking here for information to support his decision rather than information to make his decision.
