.NET 6 hosting model

[fgheysels]

.NET 6 uses a new hosting model. You can see that, when starting a new Web API project in VS.NET 2022, that the newly created project doesn't contain a Startup class anymore.
The Program.cs file consists of top-level statements:

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run();

As can be seen above, HostBuilder is no longer used (directly), instead WebApplicationBuilder is used.

Although the existing/old model that is used by .NET Core and .NET 5 is still supported by .NET 6, I feel that the Arcus Web API template must be modified so that the new hosting model is used.
