SwaggerGen Not picking up Endpoints

[xizzor77]

Hi

I am trying to add SwaggerGen to your project to automatically generate the UI with all the Endpoints that are automatically added.

This is normaly enough if the normal MapGet provided by Microsoft is beeing used.

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddApiServices();
builder.AddEndpointsApiExplorer(); 
builder.AddSwaggerGen();

var app = builder.Build();
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

Expected
Swagger UI shows all routes with their parameters

Actual
Swagger Ui does not pickup the Routes and the passed parameters. I wonder what swagger needs to find all the missing parts.
Thanks!
