Windows Form won't show with DirectX.AudioVideoPlayback - C#

Question

I'm trying to make a media player application with DirectX.AudioVideoPlayback, but when I try to run it, the project builds successfully and the application runs, but the Form doesn't show. The application just hangs on Application.Run(). However, when I comment out all of the DirectX code, the application runs like it is supposed to.

Here is my code:

Video v_Video = null;

void MainFormLoad(object sender, EventArgs e)
{
    v_Video.Size = VideoViewer.Size; //VideoViewer is a PictureBox
    v_Video.Owner = VideoViewer;
}

void PlayButtonClick(object sender, EventArgs e)
{
    v_Video = new Video(File.ReadAllText("VideoLocation.txt") + "\\Video.wmv");
    v_Video.Play();
    PauseButton.BringToFront();
}

I have used this DLL before. When I attempt to open a media file, Visual Studio throws this exception:

DLL 'C:\\Windows\\assembly\\GAC\\Microsoft.DirectX\\1.0.2902.0__31bf3856ad364e35\\Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

I suggest you using another library. Take a look here .
