Thank you Richard, and Rick. I will consult with my team on the path we may take in the future.

As I thought might happen, Rick posted an answer. Here it is: If you're shipping a vertical application your best bet is to bundle the runtimes with the application. .NET Core supports building the application in framework independent mode which includes all the runtime files required to run the application as part of the build output. IOW, you build a fully self-contained application that has no runtime dependencies on a .NET Core Framework. In your case I think this would make sense because the target machines are unlikely to have a pre-installed runtime of any kind and it side-steps the potential version mismatches. Doing this will make the distribution much larger though - a full runtime installation adds roughly 80-90megs to the application (about 30-35megs in an installer package). The other option is to rely on specific runtime versions being available. .NET Core rolls forward to higher point releases, but only up to the next point release. (ie. 3.1 and 3.2 are considered different but a 3.11 app can run on 3.15 but a 3.15 app can't run on 3.11). In the situation with churches it's unlikely that pre-existing versions of .NET Core exist, so distributing self-contained is the way to go I think. Or if that's all too much hassle - don't use .NET Core but use (full) .NET Framework instead, since that will pre-exist on any Windows machine Windows 7 and forward and just work. This is one of the main reasons why I'm sticking with full framework for the time being for any desktop, non-server application development. +++ Rick --- -- rk -----Original Message----- From: ProfoxTech <profoxtech-boun...@leafe.com> On Behalf Of Richard Kaye Sent: Tuesday, July 28, 2020 2:55 PM To: profoxt...@leafe.com Subject: RE: [NF] .NET Core build to runtime 3.1.5 with SDK for 3.1.6 installed - Possible? I thought about cross-posting it for you, Tracy. I'll act as your agent in this matter for my usual 20% commission. 😉 -- rk -----Original Message----- From: ProfoxTech <profoxtech-boun...@leafe.com> On Behalf Of Tracy Pearson Sent: Tuesday, July 28, 2020 2:39 PM To: profoxt...@leafe.com Subject: RE: [NF] .NET Core build to runtime 3.1.5 with SDK for 3.1.6 installed - Possible? Well, the required version is 3.1.4. Yet it compiled requiring 3.1.6 because that is the most recent 3.1.X installed. So the downgrade you might be thinking of is going to 3.0 which is no longer supported. Or 2.1 which doesn't have access to some of the features I'm using in C# 8. -----Original Message----- From: ProFox [mailto:profox-boun...@leafe.com] On Behalf Of Stephen Russell Sent: Tuesday, July 28, 2020 2:26 PM To: ProFox Email List Subject: Re: [NF] .NET Core build to runtime 3.1.5 with SDK for 3.1.6 installed - Possible? You can downgrade the version of core required in the project. Either way, you have to supply that in your installer. Your clients probably won't have it on thier machines. I'd consider using the M$ one because it will bring in the correct bootstraping you'll need. I only do web installs and not systems that use a forms based UI.
