C# wmp.dll -> WMPPlayState.wmppsPlaying

Hi.

Code below worked just fine like a few hours ago (song changed after previous one had stopped), but now it allways returns true. Im working with VS 2019 and it has now started to return warning

Severity Code Description Project File Line Suppression State
Warning MSB3305 Processing COM reference "WMPLib" from path "C:\WINDOWS\system32\wmp.dll". At least one of the arguments for 'IWMPGraphEventHandler.NotifyAcquireCredentials' cannot be marshaled by the runtime marshaler. Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate. 2D Sidescroller C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets 2827

if (wmp.playState != WMPPlayState.wmppsPlaying)

I have worked with keyboard inputs and not even opened class where this condition exists...i think.

hmm...after several wasted times after, i noticed this bugs out only with midi files. Changed files to wav or mp3 and all works out.
I think if i want to use midi music, a proper class for the job would be better.
