Property Value

Guid

Windows requirements

Device family	Windows 10 Anniversary Edition (introduced in 10.0.14393.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v3.0)

Remarks

Previous releases of the PlayReady API required callers to hard-code a well-known string and GUID in their code. These APIs provide those values to the caller so they can request them rather than hard-coding them.

In the MediaProtectionManager.Properties property (a PropertySet object), the "Windows.Media.Protection.MediaProtectionContainerGuid" string maps to a GUID, which will typically be the following string: ```csharp "{" + Windows.Media.Protection.PlayReady.PlayReadyStatics.ProtectionSystemId.ToString().ToUpper() + "}"
