Hello everybody,

I am going to tell frequently used extended swagger features in this article. The main contents of this article are as follows; summary, remarks, responses.

How and why to use ProducesResponseType attribute ?

Firstly, I start with response.

We have many http status code. The first things that come to mind are 200, 201, 400, 404. We use the ProducesResponseType attribute for these cases.


[ProducesResponseType(StatusCodes.Status200OK, Type = typeof(WeatherForecast[]))][ProducesResponseType(StatusCodes.Status400BadRequest, Type = typeof(BadRequestModel))]


How and why to use summary tag ?

We use to explain the api in here.

/// <summary>/// Return Whole Weather Forecasts/// </summary>


Warning !!!

We added PropertyGroup in csproj to use tags.

PropertyGroup follow below;


Also my csproj :

<Project Sdk="Microsoft.NET.Sdk.Web"><PropertyGroup>
<PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />

Then, We need add swagger option on Program.cs.

Swagger option follow below;

//using System.Reflection;builder.Services.AddSwaggerGen(options =>{var xmlFilename = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";options.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, xmlFilename));});

How and why to use remarks tag ?

Remarks tag provides explanation field for api.

/// <remarks>///  This api just get to whole **Weather Forecasts**/// </remarks>

Also, We able to bold words with twice stars.

How and why to use response tag ?

Response tag provides explanation field for responses.

/// <response code="200">Get Weather Forecast</response>/// <response code="400">Bad Request For Weather Forecast</response>
