Adding Swagger to ASP.Net Core Web API

I am trying to add Swagger to my ASP.Net Core Web API project, like this:

public void ConfigureServices(IServiceCollection services)
{
       services.AddControllers();
       services.AddSwaggerGen(c =>
       {
          c.SwaggerDoc("v0.1", new OpenApiInfo { Title = "My API", Version = "v0.1" });
       });
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            ...
            app.UseHttpsRedirection();

            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v0.1/swagger.json", "My API V1");
            });

            app.UseRouting();

            app.UseAuthorization();
            ...
}

but I am getting this error:

The type or namespace name 'OpenApiInfo' could not be found

I have installed Swashbuckle.AspNetCore v4.0.1, and my project is .Net Core 3.0.

Add the Latest version of Swashbuckle.AspNetCore package from NuGet Package Manager then it will work.

The reason it is not working is because the type OpenApiInfo comes together with the latest version of Swashbuckle.AspNetCore; open the nuget packages manager, tick the 'include prerelease' checkbox and update the package to version 5.0.0-rc3.

And then it should work.
