Add DocumentFilter after EnableSwagger has been called

I’ve got an assembly I use that provides auth, encryption, and swagger so that I don’t have to roll those things each time I stand up a new WebAPI.

Once HttpConfiguration.EnableSwagger has been called, is there a way to add another DocumentFilter, or is it too late at that point?

Ha! I did this morning @langdonx follow this link to the Swashbuckle API documentation and scroll to “Document Filter”. You are looking for public class TagDescriptionsDocumentFilter : IDocumentFilter. Add this new class to your C# project. You will need to import the following packages

using Swashbuckle.Application; using Swashbuckle.AspNetCore.Swagger;

And although they left it out in the documentation, WHICH IS KEY, you will need to add this to your Swagger definition in the ConfigureServices method in Startup.cs in your project. See example below:

// Register the Swagger generator, defining 1 or more Swagger documents services.AddSwaggerGen(c => { c.DocumentFilter<TagDescriptionsDocumentFilter>(); });

This should get you up and running! 😃

My mistake is thinking that Swagger had the information I needed when it was in the Swashbuckle documentation all along 😃

@sharrondenice I did not. 😦 Although I imagine if I were to take another crack at it, I could just send the DocumentFilters I wanted to add to the responsible assembly, and it would just inject them when appropriate.
