Add Swagger in Asp.Net Core Application.md

Add Swagger in Asp.Net Core Application

Problem

If you are using any asp.net version before 6 then chances are that swagger is not available by default.

Environment

Visual Studio, Asp.Net Core, C#

How you fix it

By installing the Swashbuckle package & by adding some code to our startup.

Solution

Install required package

dotnet add package Swashbuckle.AspNetCore

Add the following code in ConfigureServices Method in our Startup class

services.AddSwaggerGen();
services.AddSwaggerGen(c =>
{
	c.SwaggerDoc("v1", new OpenApiInfo{
		Version = "v1",
		Title = "Implement Swagger UI",
		Description = "A simple example to Implement Swagger UI",
	});
});

Then in Configure Method of the Startup.cs file add the following code:

app.UseSwagger();
app.UseSwaggerUI(c =>{
	c.SwaggerEndpoint("/swagger/v1/swagger.json", "Showing API V1");
});

Now visit the url localhost:{port}/swagger/index.html and you are good to go.
