Version 3.0.0

Getting Started

  1. Install the standard Nuget package into your Azure Functions application.
Package Manager : Install-Package AzureExtensions.Swashbuckle
CLI : dotnet add package AzureExtensions.Swashbuckle
  1. Add startup class on your Functions project.
[assembly: WebJobsStartup(typeof(SwashBuckleStartup))]
namespace YourAppNamespace
    internal class SwashBuckleStartup : IWebJobsStartup
        public void Configure(IWebJobsBuilder builder)
            //Register the extension


or you can create a more defailed configuration like this:

        public void Configure(IWebJobsBuilder builder)
            //Register the extension
            builder.AddSwashBuckle(Assembly.GetExecutingAssembly(), opts =>
                opts.SpecVersion = OpenApiSpecVersion.OpenApi2_0;
                opts.AddCodeParameter = true;
                opts.PrependOperationWithRoutePrefix = true;
                opts.Documents = new []
                    new SwaggerDocument
                        Name = "v1",
                        Title = "Swagger document",
                        Description = "Swagger test document",
                        Version = "v2"
                opts.Title = "Swagger Test";
                //opts.OverridenPathToSwaggerJson = new Uri("http://localhost:7071/api/Swagger/json");
                opts.ConfigureSwaggerGen = (x =>
                    x.CustomOperationIds(apiDesc =>
                        return apiDesc.TryGetMethodInfo(out MethodInfo methodInfo)
                            ? methodInfo.Name
                            : new Guid().ToString();
  1. Add swagger and swagger ui endpoint functions on your project.
public static class SwaggerController
    public static Task<HttpResponseMessage> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", Route = "Swagger/json")] HttpRequestMessage req,
        [SwashBuckleClient]ISwashBuckleClient swashBuckleClient)
        return Task.FromResult(swashBuckleClient.CreateSwaggerDocumentResponse(req));

    public static Task<HttpResponseMessage> Run2(
        [HttpTrigger(AuthorizationLevel.Function, "get", Route = "Swagger/ui")] HttpRequestMessage req,
        [SwashBuckleClient]ISwashBuckleClient swashBuckleClient)
        return Task.FromResult(swashBuckleClient.CreateSwaggerUIResponse(req, "swagger/json"));
