How to block the execution of a method when running EF migration
It was located in the main project, not in which the dbcontext. But either way, it should work from the main project, because for EF commands both the source project and the other project where the dbcontext is located should be specified

How to block the execution of a method when running EF migration
I found a solution which is available from .NET 7. EF exposes a static flag trough EF.IsDesignTime. I simply organized the Program.cs content in a way to only have code needed for EF in design time.

How to block the execution of a method when running EF migration
Yes, and that is what I implemented. My output shows that the DesignTimeFactory was executed and not the regular DbContext

How to block the execution of a method when running EF migration
Sorry, it turns out that IDesignTimeDbContextFactory is no longer supported in .NET 6 and above. I found a discussion on GitHub about it

How to block the execution of a method when running EF migration
For the app that external service call is essential, but it also gets executed whenever I create a migration. I think that is because the app is built one time before the EF command

How to block the execution of a method when running EF migration
The background service is an IHostedLifecycleService. I also create an instance of that just to do a http call, but all of this happens once. When I run the EF command dotnet ef migrations add ... it also executes the HTTP call. The app is not running when the migration is being created

services.AddHttpClient<ICoordinationService, CoordinationService>((serviceProvider, httpClient) =>
            {
                var options = serviceProvider.GetRequiredService<IOptions<CoordinationServiceOption>>().Value;

                httpClient.BaseAddress = new Uri(options.BaseUrl);
            })
            .ConfigurePrimaryHttpMessageHandler(() =>
                new SocketsHttpHandler { PooledConnectionLifetime = TimeSpan.FromMinutes(2) });

        var coordinationService = services.BuildServiceProvider().GetRequiredService<ICoordinationService>();
        var instanceConfig = coordinationService.GetInstanceConfig().Result;

String enums - current consensus
If you need something similar to enum just with strings then you could do the following: 
c#
public static class SortOrder
{
    public const string Ascending = "asc";

    public const string Descending = "desc";
}
c#
public static class SortOrder
{
    public const string Ascending = "asc";

    public const string Descending = "desc";
}

UUID v4 vs v7
I switched because the performance of the UUID 7 in Postgres is the same as an incremented value. A detailed benchmark can be seen here: https://ardentperf.com/2024/02/03/uuid-benchmark-war/ The only downside is that it takes up a lot of space
