Announcing C# alpha support

Semgrep v0.52.0 has advanced its C# support from development to alpha stage, boasting an estimated 97% parsing accuracy and enabling the use of metaviables and ellipsis in expressions and statements. This development allows users to write practical rules, with the first set contributed by Ahmet Akan, and the team is seeking early testers to identify bugs and contribute additional rules. The platform provides examples, tutorials, and documentation to assist users in writing Semgrep rules, and encourages those interested to upgrade or install Semgrep and consider integrating it into their CI pipelines. This milestone was largely achieved through the contributions of Sjoerd Langkemper, who significantly advanced C# support since August 2020, and there are plans to further promote C# support to beta in the coming months.
