Hi everyone,I created a metra app using C#. Then I want use the "Windows.Media.Devices.CallControl.GetDefault()" funtion to get a CallControl object.
I think the CallControl object can set\get the volume value, but then call CallControl.GetDefault, throw an exception:
"An exception of type 'System.Runtime.InteropServices.COMException' occurred in tabtest.exe but was not handled in user code
Additional information: Invalid value for registry (Exception from HRESULT: 0x80040153 (REGDB_E_INVALIDVALUE))"
How can I do?
