Use with Open API

[aherrick]

Trying to add a simple Open API integration:

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new OpenApiInfo { Title = "WebApi", Version = "v1" });
});

var app = builder.Build();

app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebApi v1"));

System.AggregateException: 'Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Swashbuckle.AspNetCore.Swagger.ISwaggerProvider Lifetime: Transient ImplementationType: Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator': Unable to resolve service for type 'Microsoft.AspNetCore.Mvc.ApiExplorer.IApiDescriptionGroupCollectionProvider' while attempting to activate 'Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator'.) (Error while validating the service descriptor 'ServiceType: Microsoft.Extensions.ApiDescriptions.IDocumentProvider Lifetime: Singleton ImplementationType: Microsoft.Extensions.ApiDescriptions.DocumentProvider': Unable to resolve service for type 'Microsoft.AspNetCore.Mvc.ApiExplorer.IApiDescriptionGroupCollectionProvider' while attempting to activate 'Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator'.)'

I got past the hard error by adding this: builder.Services.AddControllers();

But none of the endpoints are showing up:

var app = builder.Build();

app.MapGet("/api/todos", GetTodos);
app.MapGet("/api/todos/{id}", GetTodo);
app.MapPost("/api/todos", CreateTodo);
app.MapPost("/api/todos/{id}", UpdateCompleted);
app.MapDelete("/api/todos/{id}", DeleteTodo);

Swashbuckle only works with MVC at the moment.
