Fixes #155

Assume you mean: Fixes #155 ?

Looks like the actions need an update...

@crimsonhawk47 Can you please update https://github.com/crimsonhawk47/EFCore.FSharp/blob/net8-support/.github/workflows/build.yml on your branch from dotnet-version: '6.x' to dotnet-version: '8.x'

[ErikEJ]

I think maybe a lot of changes are needed for scaffolding??

Looks like the action needs a major overhaul.

Tbh, I'm looking at this for the first time in a long while and wondering how it can keep up with base EF Core The switch to T4 templates for scaffolding has kind of messed with this, T4 isn't supported in F# so options are either keep a totally separate implementation or rewrite in C#

I won't be going with a complete rewrite because I'm working on a Mac and the template engine in VS for Mac is outdated and the product is being retired anyway. Keeping the current implementation and trying to port functionality sounds like the only option I have but it's a major time investment for me so updates will be sporadic

[ErikEJ]

@simon-reynolds So you suggest releasing a .NET 8 build where scaffolding might not fully work.

[crimsonhawk47]

I'm interested in helping with this, but would like a few details.

• What do you mean you don't want to do a rewrite because "The product is being retired?" What is being retired?
• If we were able to work with C# instead for T4, would that be easier then porting functionality?

[simon-reynolds]

Visual Studio for Mac is being retired

Working with C# would make T4 functionality a bit more straightforward but we'd need to split it into two projects then as we still need F# code for mapping things like option types in queries. That would still also not solve the problem of trying to get T4 templates running on a non-Windows system as the dotnet t4 tool uses a different version of the text templating engine which causes differences in the generated code.

I've been doing some work on trying to update the existing implementation to account for API changes for .net 8 but it's not something I have a lot of time to devote to. If you're interested in helping out with the porting, I would absolutely love to have the help

I'll push my local changes to a branch later and update you here

Changes so far are on https://github.com/efcore/EFCore.FSharp/tree/net8-support It's very much work in progress at the moment and does not currently build as I'm working through the changes to EF Core's internal API's but any help would be very welcome

I've had more time to look at this lately, but I am new to doing any scaffolding. I see there were a lot of formatting changes in here. Was there any example of reimplementing a file or function for T4 templating?
