After Windows Phone 7 was released in August, it was released along with its SDK (which I used earlier). However, a new SDK was released several months later, the SDK also contains a free Visual Studio 2010 Express version. The problem arises. If the old SDK version is installed, You Need To uninstall it all before installing the new SDK version. This looks very easy, however, once a new SDK is installedProgram. This requires manual adjustments.
1. Add the attribute content in \ properties \ wmappmanifest. xml:
<Capabilities>
<Capability name = "id_cap_networking"/>
<Capability name = "id_cap_location"/>
<Capability name = "id_cap_sensors"/>
<Capability name = "id_cap_microphone"/>
<Capability name = "id_cap_medialib"/>
<Capability name = "id_cap_gamerservices"/>
<Capability name = "id_cap_phonedialer"/>
<Capability name = "id_cap_push_notification"/>
<Capability name = "id_cap_webbrowsercomponent"/>
</Capabilities>
2. If it does not work after it is added, it may be caused by a problem in Visual Studio 2010, which also needs to be changed. Because the new version is dedicated to Windows Phone.
3. If it still doesn't work, you have to recreate a new job and migrate it.
