if there is any combination of macOS, Xcode and VisualStudio that is known to work as advertised, please let me know.

Hello,

I'm quite sure you do have Xamarin.Mac, but we would need full logs to see what exact version of the dll you have and that if we need to update the tool to accommodate the newest one.

The easiest way to get exact version information:

  • On Visual Studio for Mac: "Visual Studio" menu, "About Visual Studio" item, "Show Details" button.
  • On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.

Then copy/paste the version information (you can use the "Copy Information" button).

Once we have the full info of the system, we can start looking at the fix or at least provide you a workaround.

hello @mandel-macaque

many thanks for your answer. basically we have an app that needs to call a windows DLL ('XLParser') and are currently using Mono from 2015 and the old JIT API mono_runtime_invoke() to do that. however, this causes random freezes under Mojave, so we were looking to update everything to the newest versions and most recent recommendations on how to use a DLL in a Mac app, in hopes of getting rid of that freeze.

as mentioned above i haven't even been able to call a sample DLL that just returns a string yet, so any help there would be much appreciated. here is the info you are looking for:

we really want to ship an updating with updated mono+embedding as soon as possible and would be happy to purchase paid support to get it working, if available.

The above does not show Xamarin.Mac as being installed on your computer. This is a requirement to have the e4k tool work.
