I get the exception "Common Language Runtime detected an invalid program" for this line: ImageList1.Images[0];

    ImageList1.ImageSize = new Size(112, 112);
    // Add two images to the list.
    ImageList1.Images.Add(System.Drawing.Image.FromFile("C:\\inv2026\\x64\\INV\\Usr\\Pub\\Doc\\ADSK\\INV\\Tex\\car3.BMP"));
    ImageList1.Images.Add(System.Drawing.Image.FromFile("C:\\inv2026\\x64\\INV\\Usr\\Pub\\Doc\\ADSK\\INV\\Tex\\Millennium.bmp"));

Additional context

[Evangelink]

I can reproduce the error only when using improper images but this is not linked to MSTest so I am going to close this issue.

Hi @Evangelink Thanks for you reply,Could you share me what's the "improper images". Could you give one example? Thanks.

[hyke123]

The code can work fine in ConsoleApp(net8) project. It also work fine in UnitTest Framework project.

[Evangelink]

Can you share the 2 images you are using so that I can ensure there is a bug in MSTest?

@Evangelink Thanks for your help,I think I find the root cause,the root cause is we are using 3rd plugin:typeMock.
