Using IronPython to learn the .NET framework, is this bad?
No, sounds like a good way to learn to me. You get to stick with a language and syntax that you are familiar with, and learn about the huge range of classes available in the framework, and how the CLR supports your code.
Once you've got to grips with some of the framework and the CLR services you could always pick up C# in the future. By that point it will just be a minor syntax change from what you already know.
Bare in mind that if you are thinking with respect to a career, you won't find many iron python jobs, but like I say, this could be a good way to learn about the framework first, then build on that with C# in a month or twos time.
Because I'm a Python fan, I'd like to learn the .NET framework using IronPython. Would I be missing out on something? Is this in some way not recommended?
EDIT:
I'm pretty knowledgeable of Java ( so learning/using a new language is not a problem for me ). If needed, will I be able to use everything I learned in IronPython ( excluding language featurs ) to write C# code?
