The C# documentation problem

Frequently asked questions about C# documentation

Does it work with .NET Framework projects as well as .NET Core/.NET 5+?

Yes. Codec8 reads both .csproj (SDK-style) and legacy project formats. It detects the target framework from the project file and adjusts installation instructions accordingly.

Can it document NuGet packages before they are published?

Absolutely. Codec8 reads from your GitHub source, not NuGet. It generates documentation that you can include in your NuGet package or GitHub repository independently.

How does it handle nullable reference types enabled in C# 8+?

Codec8 reads your nullable context settings and incorporates nullability annotations into the API documentation, clearly marking parameters and returns as nullable or non-nullable.
