Source Generator

Refitter is available as a C# Source Generator that uses the Refitter.Core library for generating a REST API Client using the Refit library. Refitter can generate the Refit interface from OpenAPI specifications. Refitter could format the generated Refit interface to be managed by Apizr (v6+) and generate some registration helpers too.

Starting with v2.0.0, the source generator emits code in-memory through Roslyn AddSource() instead of writing .g.cs files to disk. Use your IDE's generated-files view to inspect the output. If your workflow requires physical generated files for review, commits, or build scripts, use Refitter CLI or Refitter.MSBuild instead.

Installation

The source generator is distributed as a NuGet package and should be installed to the project that will contain the generated code

dotnet add package Refitter.SourceGenerator
dotnet add package Refit

Refitter.SourceGenerator keeps its Refit dependency private, so consuming projects must add their own direct package reference to Refit. If you use generated dependency-injection helpers such as ConfigureRefitClients(), also add Refit.HttpClientFactory explicitly.

Usage

After installing the package, add one or more .refitter files to your project.

Refitter.SourceGenerator automatically includes **/*.refitter as Roslyn AdditionalFiles via its package props, so you do not need to add manual <AdditionalFiles Include="..." /> entries unless you intentionally override that default behavior.
