Features:

• MIT licensed with no extra bs, unlike Mime Detective; online demo included.
• Works on anything from .NET 4 to the newest .NET Core, .netstandard 1.2 is supported too. When using newer runtimes, the library utilizes some perf/qol niceties (Span, FileStream, FrozenDictionary..)
• 2,000+ MIME/file extensions pairs (double that of MimeTypeMap), get one from the other, even without having a Stream. Sourced from IANA and other authoritative sources.
• If you have a Stream, pass it along and get the file header sampled if needed (for example, .ts can be either a TypeScript file or a Transport Stream MPEG video).
• Available on NuGet now as MimeTypeCore.
• Integrations for Blazor Server, WASM, MVC.
• Development tooling included to ease merging of contributions, including utils like Formatter, Inserter, Generator, and GitHub actions CI/CD.
• NUnit tested.
