Media platform failed to initialize

[DynTechieBibin]

I'm working on application-hosted media bot and getting the following exception while testing locally on Windows 11:
Unable to load DLL 'NativeMedia' or one of its dependencies.

This exception occurs from the line:
builder.SetMediaPlatformSettings(mediaPlatformSettings);

var mediaPlatformSettings = new MediaPlatformSettings()
{
MediaPlatformInstanceSettings = new MediaPlatformInstanceSettings()
{
CertificateThumbprint = sthumbprint,
InstanceInternalPort = internalPort,
InstancePublicIPAddress = IPAddress.Any,
InstancePublicPort = publicPort,
ServiceFqdn = config.ServiceFqdn
},
ApplicationId = config.APP_ID,
};

Install package Microsoft.Skype.Bots.Media. Even though it is within Microsoft.Graph.Communications.Calls.Media package, it seems the whole skype bot dependent dlls are not there.

Congrats to finding your own solution!

I guess you could also close the issue then :)

@tranguyendinh Your issue is unrelated. The error message you shared is pretty clear about the cause of the issue:

---> System.ArgumentException: CertificateThumbprint (Parameter 'Could not find a matching certificate for thumbprint 9E95EBE782871401573B547F603FCD2D797FFDD6')

If you need more help, I'd suggest opening a separate issue to keep things searchable
