How to develop Windows Mobile 6.5 apps

I'm new to Windows Mobile 6.5 app development. Which language 开发者_如何学JAVAdo I need to learn and which books are preferable? Can you direct me to eBook sites for Windows Mobile apps development?

You actually have a choice between C++, C#, or Visual Basic since Windows Mobile supports multiple languages. You will likely need to use Visual Studio for easiest end-to-end development (you can get express for free). I don't know of any good books to recommend, but you can use Microsoft's official tutorial here.

Finally, you can find the SDK here.
