What's the issue with porting them to .net (core)? Most of that stuff is still supported, if you only have native windows DLLs you would still be constrained to windows only, but still better than staying on ancient .net framework.

If you are stuck on Windows and upgrade to Core requires more then 2 hours of dev time, it's likely not worth it. Core biggest feature is running on Linux. If you can't, who cares? Framework is not going anywhere. It will be supported till 2035 for now.

There are so many features that .Net 5+ brings to the table. Even if features aren’t important the performance improvements you get with the newer versions should be enough to justify moving to it.

I agree the support side is annoying but honestly the support side is really just “security” fixes with security being a very hard thing to describe here and gives MS a lot of wiggle room to not actually support it.

No, linux support is not the only new feature. Read the change logs, it's thousands of huge improvements everywhere.

As someone who deals with this, Framework -> Core on Windows is small % performance improvement. Framework Windows -> Core on Linux is huge. Most of it coming from not Windows.

Yes, there is other nice language features but obviously 15 years of Framework code base has probably put up guard rails around those sharp edges.

My point still stands, I can't imagine most companies green lighting .Net Framework -> Core conversion if they can't switch to Linux. If you are stuck on Windows, you have probably developed all the tooling to deal with Windows so it's all sunk costs.

Linux was rarely part of the conversation when I was doing these conversions.

Getting access to things like Kestrel (breaking out of IIS jail) is way more critical. Also, self contained deployments mean you can stop shipping magical blessed machine images around. It's not even about the performance. It's about having technology that doesn't actively hate you.

We solved that headache with Windows containers, but yeah that is literally shipping a blessed machine in disguise.

Adding to this, IME, doco for .NET Framework is increasingly hard to find because the .NET Core stuff bubbles up in its place - possibly also because Google is absolute trash these days. Not a big deal if you have some hardcore .NET lifers who know Framework inside out.. but I'd say those are heavily outnumbered, and eventually going to move on to goose farming anyway.

		I can tell you that in regards to that, being around .NET since day zero is really advantageous for actually being able to find what I wanted. Also they aren't the only ones, same applies on the Apple ecosystem, only those around Mac OS and OS X early days actually manage to find sensible documentation.

Someone has to pay for the work.
