What is the purpose of your .tt files?

Very cool library! I have been following you for a while over at https://github.com/vkhorikov/CSharpFunctionalExtensions

I very very much appreciate your use of xxxAsync methods, the compiler I found would have issues with it, and also, it was hard to mix nested sync and async methods together implicitly, rather than explicitly.

My question is:

• In your code base, what is the purpose of your .tt and .t4 files? I know that they are for code-generation, but how are they used?

Thanks!

The template (T4) is used to generate this code
https://github.com/xavierjohn/FunctionalDDD/blob/main/Core/src/Functional/Result/Extensions/BindTs.cs

If you use Visual Studio, T4 to cs file is generated when the t4 file is saved.

Ah makes perfect sense, would not be fun to write that for each method implementation type.

Thanks for educating me!

PS: I was a long time VS user, love love VS, but it was 'heavy', so I use Rider now. But for some more exotic things like Incremental Source Generator development, some types of unit testing, and apprently .t4 files also, VS is the better option. I use VS in select scenarios like this.

Unpopular opinion - Vs Code is an abomination to C# 🙃

Is it possible to mark this as 'answered'? I don't see the option for it.

Thanks for the fastest answer ever! <3
