The F# Type Provider SDK

The F# Type Provider SDK (TPSDK) is the standard library for building F# type providers. It provides ProvidedTypes.fs, a single source file that implements the full Type Provider API, including erased and generative type definitions, static parameters, quotation support, and cross-targeting infrastructure.

Quick Start

Create a new type provider from the template:

dotnet new -i FSharp.TypeProviders.Templates
dotnet new typeprovider -n MyProvider -lang F#
cd MyProvider
dotnet tool restore
dotnet paket update
dotnet build -c Release
dotnet test -c Release

Documentation


Quick Start	Install the template, understand the project structure, and build your first erased type provider with a constructor, property, and method.
Complete Guide	Erased vs generative providers, testing, debugging, and packaging overview.
Providing Types, Members, and Features	Static parameters, quotations, generative providers, all member kinds, interfaces, enumerations, nested types, XML docs, custom attributes, units of measure, non-nullability, and abstract classes.
Packaging	NuGet package layout, how `IsFSharpDesignTimeProvider` automates packaging and build-time tool collection, bundling dependencies, and the assembly replacement map.
Units of Measure	SI units, compound units, custom units, and annotating numeric types with `ProvidedMeasureBuilder`.
Technical Notes	Design-time vs runtime components, naming conventions, NuGet package layout, lifetime of type provider instances, quotation construction, and API reference for key features.
Debugging	How to debug a type provider running inside `fsc.exe`, `dotnet fsi`, Visual Studio, or Ionide.

Examples

See the examples directory for BasicProvider (both erased and generative variants) and StressProvider.

Using the SDK via NuGet

Instead of source-including ProvidedTypes.fs, you can reference the SDK as a NuGet package in the design-time component:

<PackageReference Include="FSharp.TypeProviders.SDK" Version="8.0.0">
  <PrivateAssets>all</PrivateAssets>
</PackageReference>
<PackageReference Update="FSharp.Core" Version="8.0.0">
  <ExcludeAssets>all</ExcludeAssets>
</PackageReference>

The runtime component should not reference FSharp.TypeProviders.SDK.
