I've been exploring AI Agents recently and they look extremely promising.  More on this in due course.

I've been experimenting a lot using Oqtane over the last 2 months and like it quite a lot.

I upgraded this website to .NET9 at the weekend. That was straightforward, I just had to update Visual Studio 2022 to the latest version and then upgrading the site amounted to just changing the target in its project file. I also tried upgrading the associated function, but it seems (as too often with Microsoft releases) that .NET 9 is not yet really fully available. It doesn't work with functions yet!

I have just upgraded this website from .NET 7 to .NET 8, and also the associated Azure function from .NET 6 in-process to .NET 8 isolated. Upgrading an app service (website) from .NET 7 (or 6) to .NET 8 is pretty straightforward and essentially just involves changing the target framework ...

For security reasons, you should not be storing production setting values in source control. But this means that by default, you don't have your own backup of the values for your live, production settings. What if you want to store a copy of your settings (e.g. along with the artifacts) ...

I was able to migrate a legacy project using .net framework and entity framework to .NET 7 and EFCore relatively easily. EFCore Power Tools was very useful in doing a first draft of model code from the existing database.

Upgrading a .NET 6 to .NET 7 app service seems very straightforward. Upgrading Azure functions to .NET 7 looks to be a more significant change, and might require some investigation first.

If your legacy code uses Entity Framework 6.3.3 or later, you don't necessarily need to move to Entity Framework Core at the same time that you move from .net framework 4.7/4.8 to .NET 6 or 7.

One possible solution to a "You are using TLS version 1.0, 1.1 and/or 3DES cipher which are deprecated" error might be to upgrade any older app services that are using older versions of .net framework.

Microsoft's Natural Language Processing LUIS apps seem to be deprecated in favour of CLU but are currently difficult to migrate. However the LUIS apps still seem to work - for now at least!
