Configure an app package by using the manifest designer

Applies to Windows and Windows Phone

The app manifest file, package.appxmanifest.xml, contains properties and settings that are required when you submit your app to the Store. For example, properties in the manifest file describe the image to use as the tile of your app or the orientations that your app supports when a user rotates the device.

Visual Studio includes a manifest designer that makes it easy for you to update the manifest file without editing the raw XML of the file.

  1. In Visual Studio, close the manifest file if it’s already open in XML code view.

  2. In Solution Explorer, expand the project node of the app.

  3. Double-click the Package.appxmanifest file.

    If the manifest file is already open in XML code view, Visual Studio prompts you to close the file.

The following table lists the configuration tasks that you can perform in each page of the manifest designer.

This topic identifies the tasks and directs you to topics that can help you understand the trade-offs of decisions related to the task and then to help you accomplish the task end-to-end. In some cases the task requires that you write code.

If you just want to view the definition of a field, you can do that by pointing to it in the designer. As you modify settings, an error icon might appear if further actions are required by you to complete the configuration. If an error icon appears, you can view the error message by pointing to it in the designer.

Guidance

Application

Specify the orientations that your app supports when a user rotates the device: landscape, portrait, landscape-flipped, portrait-flipped, or any combination of these options.

InitialRotationPreference

Applies to Windows only

Specify the minimum width of your app.

If you want your app to appear on smaller screens without requiring a user to scroll horizontally, you can reduce the minimum size of your app and then design it to function well at that minimum size.

Applies to Windows Phone only

Prevent your app from being installed on an SD card.

You can ensure that apps only install to a device and not to the SD card of a phone. You might choose to do this if you’re concerned about the security of your app and it’s data or you’ve tested the app on an SD card and it does not perform well.

Enable your app to raise toast notifications.

Configure an app to receive toast notifications.

Understand the guidelines for showing toast notifications.

Guidelines for toast notifications

Download and run a sample that uses toast notifications.

Toast notifications sample

Specify how and when tiles in your app are updated.

Periodic notifications, which are sometimes called polled notifications, update tiles and badges at a fixed interval by downloading content directly from a cloud service.

Visual Assets

Choose the various types of images that will represent your app.

Choosing your app images

Optimize images so that they look good at any resolution.

Optimizing images for different screen resolutions

Add tile images

Some of the logos that you provide in the designer appear as tiles in the Start screen.

See where Store logos appear.

Add a badge logo to the lock screen.

This topic shows you how to modify the XML of the app manifest. You can enable this experience by using properties in the Visual Assets tab of the manifest designer.

Requirements

Applies to Windows Phone only

Specify the hardware requirements of your app

Users won’t be able to download and install apps unless their device meets the hardware requirements that you specify.

If your app requires one of the following hardware features, make sure you select the corresponding requirement.

  • Gyroscope

  • Magnetometer (compass)

  • NFC

  • Front Camera

  • Rear Camera

Capabilities

Provide programmatic access to user resources.

Store apps that need programmatic access to user resources, such as Pictures, or connected devices, such as a webcam, must declare the appropriate capability. The Store lists those declarations so that users can make informed decisions about whether to download and use your app. Learn about the different capabilities that you can choose in this designer. This topic also contains links to quickstart tutorials that show the code that you can write to access the resources that you declare.

App capability declarations

Declarations

Connect your app to people, devices, and services.

You can extend or customize standard Windows features in your app or interoperate and even share information with other apps.

App contracts and extensions

Content URIs

Enable pages that your app loads to access geolocation devices and the Clipboard.

If your app navigates to a remote page, that page runs in the web context and has limited access to your system. You can use the properties in the Content URIs tab to give a webpage access to geolocation devices and the Clipboard.

Packaging

Set the properties that are used to package your app.
