This is a drop-in, FOSS replacement for Microsoft.Typescript.Msbuild.

dotnet add package BlazingTs

Create the tsconfig.json file in your project and build it. BlazingTS will invoke bundled tsc during the BeforeBuild phase of MSBuild and transpile your ts/tsx into js/jsx files.

BlazingTS targets netstandard2.0, hence, it's compatible with almost any version of .NET Core / .NET Framework. The library is cross-platform, supporting Linux, Windows, and MacOS. A GitHub action automatically updates the library, checking for a new release of TypeScript (on NPM) daily. If a new version is released, the library is updated automatically and a new release on NuGet is created. Therefore, new versions of TypeScript are available immediately, unlike Microsoft.Typescript.Msbuild which is updated manually by a maintainer, resulting in a significant delay/skipping of (minor) releases altogether.
