Description
Before I was having something like this:
```c#
public static class Program
{
private static async Task Main(string[] args)
{
var host = CreateHostBuilder(args).Build();
await host.RunAsync();
}
public static IHostBuilder CreateHostBuilder(params string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureHostConfiguration(builder => { })
.ConfigureAppConfiguration((context, builder) => { })
.ConfigureLogging((context, logging) => { })
.ConfigureWebHostDefaults(builder => builder.UseStartup());
}
```
and then
```c#
[TestClass]
public class HostTests
{
[TestMethod]
public void Build_Should_Return_Host_With_Valid_Services()
{
var builder = Program.CreateHostBuilder()
.UseDefaultServiceProvider(options =>
{
options.ValidateScopes = true;
options.ValidateOnBuild = true;
});
var host = builder.Build();
host.Should().NotBeNull();
}
}
```
so it would fail in case of the DI container misconfiguration. Not always, but at least a basic smoke test.
What would be an alternative in the Minimal API and .NET 7?
