+### Native AOT support
+
+GraphQL.NET Server fully supports Native AOT publishing with .NET 8.0 and later.
+See [ASP.NET Core support for Native AOT](https://learn.microsoft.com/en-us/aspnet/core/fundamentals/native-aot)
+for a list of features supported by .NET 8.0.  However, GraphQL.NET only provides limited
+support for Native AOT publishing due to its extensive use of reflection.  Please see
+[GraphQL.NET Ahead-of-time compilation](https://github.com/graphql-dotnet/graphql-dotnet?tab=readme-ov-file#ahead-of-time-compilation)
+for more information.
