Generating Program.cs class for testing purposes

This is how you can use Program .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk.Web">

<PropertyGroup>
<TargetFramework>net10.0</TargetFramework>
<Nullable>enable</Nullable>
<ImplicitUsings>enable</ImplicitUsings>
<InvariantGlobalization>true</InvariantGlobalization>
<PublishAot>true</PublishAot>
</PropertyGroup>

<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.OpenApi" Version="10.0.0" />
</ItemGroup>
<PropertyGroup>
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
</PropertyGroup>
</Project>

The code that you will use is

using System.Text.Json.Serialization;
using Microsoft.AspNetCore.Http.HttpResults;

var builder = WebApplication.CreateSlimBuilder(args);

builder.Services.ConfigureHttpJsonOptions(options =>
{
options.SerializerOptions.TypeInfoResolverChain.Insert(0, AppJsonSerializerContext.Default);
});

// Learn more about configuring OpenAPI at https://aka.ms/aspnet/openapi
builder.Services.AddOpenApi();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
app.MapOpenApi();
}

Todo[] sampleTodos =
[
new(1, "Walk the dog"),
new(2, "Do the dishes", DateOnly.FromDateTime(DateTime.Now)),
new(3, "Do the laundry", DateOnly.FromDateTime(DateTime.Now.AddDays(1))),
new(4, "Clean the bathroom"),
new(5, "Clean the car", DateOnly.FromDateTime(DateTime.Now.AddDays(2)))
];

var todosApi = app.MapGroup("/todos");
todosApi.MapGet("/", () => sampleTodos)
.WithName("GetTodos");

todosApi.MapGet("/{id}", Results<Ok<Todo>, NotFound&gt; (int id) =&gt;
sampleTodos.FirstOrDefault(a =&gt; a.Id == id) is { } todo
? TypedResults.Ok(todo)
: TypedResults.NotFound())
.WithName("GetTodoById");

app.Run();

public record Todo(int Id, string? Title, DateOnly? DueBy = null, bool IsComplete = false);

[JsonSerializable(typeof(Todo[]))]
internal partial class AppJsonSerializerContext : JsonSerializerContext
{

}

The code that is generated is

// <auto-generated />
///

<summary>
/// Auto-generated public partial Program class for top-level statement apps.
/// </summary>
public partial class Program { }
