Describe your Issue:

After updating my XF app from XF 4.4 to 4.5 vs started to ask me to migrate to AndroidX. And after migrating both manually using VS 2019 (ver 16.4.5) or using the migration tool on VS 2019 Preview (ver 16.5.0 Preview 5.0) I have stucked on the build error as described on the stacktrace bellow:

Steps to Reproduce (with link to sample solution if possible):

I can provide a private copy of my solution code to MSFT if needed.

Include any relevant Exception Stack traces, build logs, adb logs:

@moljac BTW I’ve just succeeded.

  1. Go to “Tools -> Options -> Xamarin” and enabled the option “Enable AndroidX Migrator (Experimental)”
  2. Updated all the AndroidX nuget packages that VS Migration Tool have installed (The migration tool installs outdated -pre releases of AndroidX) so you need to update to the latest stable version from nuget.org. Without this I was still getting those Cecil.*** errors.
  3. Try to build the project and if VS complain about some missing AndroidX nuget package, just install them and you’re ok.
