Adapt combobox to work on scale

Question

I'm developing a software in c# using Microsft Visual Studio 2017 where I have some comboboxes in it. Everything works correctly regardless of the screen resolution but, when I set a different scale from 100% all the comboboxes show very small.

See pictures below to better understanding:

100% Scale:

175% Scale:

As you can see, combobox looks smaller as much as I get a bigger scale factor in my Windows configuration. How can I maintain the same size ratio when I change the scale?

These are the settings that I have for my comboBox:

And this are the settings of my form:

Thanks for the help!

Edit you `app.manifest` (add one if, for some reasons, is missing in your Project).

I think you should set the Forms properties to

AutoSize = True
AutoSizeMode = GrowAndShrink

( I've also seen that in combination with these settings above the AutoScaleMode was set to "None" before it actually worked)

Can you give that a try?

Finally I found a way that "solved" the problem. After creating the .exe file, I make right click and select Properties:

After that, select Compatibility and set this configuration (I'm sorry, my SO is in spanish):

After setting this, Windows will rescale correctly.
