Free software for Windows Mobile application development

I hope this question is not too off-topic, if it is this post can be deleted.

I am a programmer/webdeveloper in mainly Java and PHP. I have some free time on my hand and want to play a little with mobile application development.

Now the first links I found on Google tells me how to build an application using Visual Studio.

I am only going to play around with it for a few days so I am not planning on buying that package just for that. My webdevelopment and programming is done in Dreamweaver and Eclipse.

Are th开发者_Python百科ere any free alternatives to develop WM applications? I doubt that there is any eclipse version that deals with WM.

I don't know of Open Source tools to develop Windows Phone 7 apps, however, if you are just looking for FREE tools, the Windows 7 tools come with Visual Studio Express, which is everything you need to get started writing for the phone.
