    configuration.Title = "MyApp";
    configuration.Version = typeof(Program).Assembly.GetSimplifiedVersion();
});

}

Configuration MVC

Startup.cs

using NJsonSchema;
using NSwag.AspNetCore;
using System.Reflection;

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseMvc();

    // à ajouter avant app.UseSpa
    app.UseSwaggerUi(typeof(Startup).GetTypeInfo().Assembly, settings =>
    {
        settings.GeneratorSettings.DefaultPropertyNameHandling = PropertyNameHandling.CamelCase;
        settings.PostProcess = document =>
        {
            //document.Info.Version = "v1";
            document.Info.Title = "Test API";
            document.Info.Description = "A simple ASP.NET Core web API";
            //document.Info.TermsOfService = "None";
            document.Info.Contact = new NSwag.SwaggerContact
            {
                Name = "Nicolas",
                //Email = string.Empty,
                //Url = "https://twitter.com/spboyer"
            };
            /*document.Info.License = new NSwag.SwaggerLicense
            {
                Name = "Use under LICX",
                Url = "https://example.com/license"
            };*/
        };
    });

Problème avec IActionResult

NSwag utilise la réflexion pour obtenir le type de retour. Avec IActionResult il ne peut pas.

[HttpGet]
// utiliser SwaggerResponse
[SwaggerResponse(HttpStatusCode.OK, typeof(IReadOnlyList<ItemDto>))]
[SwaggerResponse(HttpStatusCode.BadRequest, typeof(void))]
// ou ProducesResponseType
[ProducesResponseType(typeof(IReadOnlyList<ItemDto>), StatusCodes.Status200OK)]
public IActionResult Get()
