price of developer license for Windows Phone 7?

Does Microsoft offer developer license for professionals and 开发者_开发技巧students? Is there a special student program?

If you're simply interested in developing using the emulator, there is no license fee to pay. Just download the tools and go to town.

Scott Guthrie actually has a good write-up of all the tools you'll need to download (for free) and how to get started:

Registering for the Marketplace to sell your apps is another story. You will have to pay a $99 fee to create your account there unless you are a student participating in Microsoft's DreamSpark program (in which case the registration is free there as well).

To develop applications, it's free.

But if you need to know the price to submit your apps to the marketplace:

Check out Windows Development App Hub

It's $99 US Dollers or £65 in the UK.

That allows you to submit 5 applications. It is $19.99 for each app after that. If you are a student, you get a load of tools free. You can access the student membership via the link above.

the registration prices are here ($99) - http://create.msdn.com/en-US/home/membership
