How come errors show when application in built in "Release" mode and don't when built in "Debug" mode

Question

I have developed an application in Visual Studio 2017, Visual Basic to be exact and I am confused. I developed the program and built it in debug mode to test out the application. The build process shows no errors, warnings, or messages and the program executes as designed. However, when I rebuild the project in release mode I get the exception:

Application does not support just-in-time (JIT)
debugging. See the end of this message for details.

I don’t understand why. There should be no difference between Debug and Release.

So why is this happening?

Thank you,

Answer 1

Add the image as a resource. In the code you'll need a few few changes,

        PictureBox1.Image = My.Resources.Save 'don't need extension
        ' OR
        Dim img As Image = My.Resources.Save
        PictureBox1.Image = img

Answer 2

Hi! That error is saying that the Save.bmp file is missing from the output folder. Debug and Release modes go to different folders. You probably manually copied the Save.bmp file to the debug folder at some point. You should instead add the Save.bmp file to your project, select it in the Solution Explorer window, and then in the Properties window set Copy to output folder to Always.
