Hello Awesome Windows Server Team, markosmezgebu, @taylorb_msft
we are in the process of re-platforming an enterprise application to the Windows Containers.
our application is running with .Net Framework and can run on a Virtual Machine with
Windows Server Core 2019 + "app compat Feat on demand"
When we try to do the same install with the containers, the installer for the "App Compat FoD" Fails inside the container build.
So we can't seem to be able to find a good way to add the missing libraries inside a Windows Core 2019 Container,
and we are only left with the choice of using the "full windows image" container.
What is the easiest way to add the libraries from the "App Compat FoD" into the Win Server Core Container 2019 ?
Would Microsoft consider building a "Windows Core 2019 Container ++ ? " which would include the App Compate FoD ?
I would bet that there are many companies trying to move ".Net Framework" applications to Containers,
without/before re-writing them in ".Net Core". so you would really be helping all of us out there if you can show a way to handle this.
