In Windows Phone OS 7.0, the DeviceExtendedProperties class was used to query device-specific properties. In Windows Phone OS 7.1, most of the properties in DeviceExtendedProperties were deprecated, and the new DeviceStatus class should be used instead. However, where appropriate, you can still use the properties in DeviceExtendedProperties that are not deprecated. |
For a full list of properties that can be queried by this method, see DeviceExtendedProperties.
GetValue(String) either will return a non-null object containing the requested value or will throw one of the exceptions listed in the following table. TryGetValue(String, Object) provides the same functionality as GetValue(String), but uses a different syntax that you may prefer.
| Important Note: |
|---|
DeviceExtendedProperties requires the device identity capability. If your application uses this class, the user will be alerted that the application requires access to the device identity when viewing your application on Windows Phone Marketplace. However, if you use the GetValue method to get the ApplicationWorkingSetLimit, you can opt out of the device identity capability by removing it from the application manifest prior to application ingestion and it will not be added back in during the ingestion process. |
This method may throw one of the following exceptions.
ArgumentNullException | The specified property name is null. |
ArgumentOutOfRangeException | The specified property does not exist. |
UnauthorizedAccessException | The capability to retrieve the property has not been granted. |
NotSupportedException | The specified property cannot be retrieved. |
