In the last article, I talked about the specific requirements and recommendations regarding Windows Phone 7 iconography, including images for your application's tiles, the Marketplace, and application bar buttons. This time, I want to take it a step further and sum up all of the most important key points of the application certification requirements in the form of a cheat sheet.

The full requirements can be found online on MSDN. The following will provide you short summaries of the technical and submission requirements as well as the application policies. The order is not necessarily the same as in the original documentation, to structure the information a bit more for a developer's view. Please note that this is not a normal article. It is not intended to be read from top to bottom – instead it is meant as a reference for quick look-ups where you don't want to click through/search the complete requirements online. You can download a handy single-page PDF/XPS version at the end of the article which for example can be printed out and pinned to a wall in your working space, so you have everything at hand with a quick look.

Make sure your application also complies with the Content Policies and the additional requirements for special types of applications (if applicable), which are not covered by this article.

Applications in General

Some general application policies are listed in the following:

  • Must include the name, version and technical support contact information (5.6)
  • Must not use in-app purchases; app must be ready to use after acquisition (2.1)
  • Must not sell or promote mobile voice plans (2.2)
  • Must provide information in the description when the download of additional large data packages is required (2.5)
  • Must comply with the Microsoft Advertising Creative Acceptance Policy Guide for all in-app advertising (2.4)
  • Must verify age > 13 for user accounts in person-to-person communication feature scenarios (2.6)
  • Must use "opt-in" and provide "opt-out" later to share a user's personal information (2.8)
  • Must have purpose other than merely launching a webpage (2.10)
  • Must ensure all content is visible and legible with all phone themes (dark/light) (5.5.2)

XAP Package (4.1.1)

The requirements for the packaging of your application have information on the following topics (4.1.1):

Maximum size

        225 MB

Required content
  • WMAppManifest.xml
  • AppManifest.xml
  • Assembly files specified in AppManifest.xml
  • Small and large app tile images
Required for WMAppManifest.xml
  • The title element must not be empty
  • The title element must be the same as the specified title during submission

Please note that these requirements partly have changed over time, for example the former size limit was 400 MB.

Code Validation

To succeed code validation, an application must adhere to the following rules:

  • Must not use P/Invoke (4.2.2)
  • Must not use COM interop (4.2.2)
  • Must be built in release mode; must not contain debugging symbols/output (4.2.3)
  • Must not redistribute phone assemblies (4.2.4)
  • Must not use XNA Game or Graphics assembly when using System.Windows.Controls (4.2.5)

Phone Capabilities (4.3)

The phone capabilities an application makes use of are contained in the WMAppManifest.xml and automatically determined during submission.

  • The application must run with the automatically detected capabilities (4.3)
    • Use the Capability Detection Tool to determine the capabilities for your application and test AND/OR
    • Use the "Mango" Marketplace Test Kit's Capability Validation for this

Languages

Every application must be localized to at least one of the following supported languages (4.4):

  • English
  • French
  • Italian
  • German
  • Spanish

In addition, the following requirements are in place:

  • Must set a neutral language (4.4)
  • Must localize the application description and UI texts to each supported language (5.5.1)

Icons/Images (4.5, 4.6, 4.7)

For a more sophisticated description of the Windows Phone 7 iconography that explains the following information in more detail, please read my separate article on the topic.

Large app tile image Yes PNG Yes 173x173
Small Marketplace mobile tile image Yes PNG No 99x99

  • For games: during gameplay, can open dialog/pause menu (5.2.4.4)

The back button must not be used for any other functionality than what is listed above.

Reliability, Security and More

The following requirements are in place regarding general reliability, security and issues regarding the phone's built-in functionality:

  • Must run on any Windows Phone device (5.1.1)
  • Must not close unexpectedly due to unhandled exceptions or other reasons (5.1.2, 5.3.3)

Location Aware Applications

For apps that use the location of a user's device, the following restrictions and requirements apply:
