Windows mobile Applications

Development

Third party applications and games for Windows Phone are based on XNA or a WP7 specific version of Silverlight.For Windows Phone apps to be designed and tested within Visual Studio 2010 or Visual Studio 2010 Express editions, Microsoft offers Windows Phone Developer Tools as an extension. Windows Phone Developer Tools run only on Windows Vista SP2 and later. Microsoft also offers Expression Blend for Windows Phone for free. On November 29, 2009, Microsoft announced the Release to web (RTW) version of its Visual Basic .NET Developer Tool, to allow development in Visual Basic.As it shares much of its platform, Windows Phone 8 will support the running of managed code through a Common Language Runtime similar to that of the Windows operating system itself as opposed to the .NET Compact Framework. This, along with support for native C and C++ libraries, will allow some Windows programs to be easily ported to Windows Phone 8.

Submission

Registered Windows Phone and Xbox Live developers can submit and manage their third party applications for the platforms through the App Hub web applications. The App Hub provides development tools and support for third-party application developers. The submitted applications undergo an approval process for verifications and validations to check if they qualify the applications standardization criteria set by Microsoft. The cost of the applications that are approved is up to the developer, but Microsoft will take 30% of the revenue (the other 70% goes to the developer). Microsoft will only pay developers once they reach a set sales figure, and will withhold 30% tax from non-US developers, unless they first register with the United States Government's Internal Revenue Service. Microsoft only pays developers from a list of thirty countries. A yearly fee is also payable for developers wishing to submit apps.In order to get an application to appear in the Windows Phone Store, the application must be submitted to Microsoft for approval. Microsoft has outlined the content that it will not allow in the applications, which includes content that, among other things, advocates discrimination or hate, promotes usage of drugs, alcohol or tobacco, or includes sexually suggestive material.
