C# grammar for [tree-sitter](https://github.com/tree-sitter/tree-sitter) based upon the Roslyn grammar with changes in order to:

- Deal with differences between the parsing technologies

- Work around some bugs in that grammar

- Handle `#if`, `#else`, `#elif`, `#endif` blocks

- Support syntax highlighting/parsing of fragments

- Simplify the output tree

- Reduce parser state count and complexity

- Be in-line with tree-sitter's convention where applicable

### Status

Comprehensive supports C# 1 through 13.0 with the following exception:

- [ ] `async`, `var` and `await` cannot be used as identifiers everywhere they are valid

### References

- [Official C# 6 Language Spec](https://github.com/dotnet/csharplang/blob/master/spec/) provides chapters that formally define the language grammar.
