.NET support for custom resource providers has been introduced in a preview release, allowing developers to create custom providers using .NET languages such as C#, F#, and VB.NET. This initial release is feature complete but comes with minimal documentation, as the team seeks early feedback to improve the API before a production-quality release. To access the new APIs, developers need to use version 3.52.0, which can be added to projects via the .NET package manager. An example of the provider interface is available in the dotnet integration tests directory, replacing the previous Go-based test provider. Developers are encouraged to provide feedback and engage in discussions on GitHub or the Community Slack's #dotnet channel.
