Top-level statements

Hello,

The .NET Languages Add-on currently supports through C# 8 syntax, and top-level statements are a C# 9 feature.  We will add your request to the TODO item for upgrading the add-on for C# 9 features.

Yes please, same, waiting for this useful feature.

Hello,

1 year later, it seems that this feature is still not implemented, will it be integrated and when ?

Hello,

We had some other projects the past year that took longer than we had hoped.  We plan to cycle back and work on SyntaxEditor updates again soon, once we get past what we are currently on.

Hello,

As an update to this thread, we expect to launch C# 9.0 support, including top-level statements, for the SyntaxEditor .NET Languages Add-on in v24.1.

Great news, thank you !!

I've recomment to support for https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-10#file-scoped-namespace-declaration feature. Right now it is like a standard to create all new code outlined.

You no need support all features I suppose (some features really exotic and more like experimental). But major features in each C# lang versions should be present in your parser. Good for you - this features are really not to much. For example, in C# 11 it is only generic attributes and raw literals (not sure this is really required to make some changes in the parser) that I've seen in real apps sources.

So my proposal is - do not waste a time for support all features in news lang versions. Just a really popular and usefull things are really need (by feedbacks you can understand what is popular and not).

Hello,

It would be nice to do that since there are some much-less used features that can take time to implement, however there are a couple issues with that approach:

1. We need to be able to clearly say which version of C# we support.  If we only implemented selected version features, we would no longer be able to say we can parse C# properly at a given version.
2. Many new features introduced build on the backs of previous features.  For instance, C# 9 added more patterns and patterns were introduced in a prior version.  C# 9 adds records but then the next version adds record structs, and so on.  Therefore we really need to make sure we fully implement a version's features for future versions to work properly.  It would be too difficult to track what was or was not implemented years down the road.
