Problem with HealthChecks.UI.SqlServer.Storage migrations

Question

I'm trying to use Healthchecks UI in my asp.net core application with SqlServer.Storage for history purposes. It works with InMemoryStorage (without history part, of course).

So, Startup.cs code is like this:

services.AddHealthChecks()
    .AddHangfire(...)
    .AddDbContextCheck<...>("Database")
    .AddAzureBlobStorage(...)
    .AddProcessAllocatedMemoryHealthCheck(...)
    .AddCheck(...);

services
    .AddHealthChecksUI(settings =>
    {
        settings.SetEvaluationTimeInSeconds(...);
        settings.SetMinimumSecondsBetweenFailureNotifications(...);
        settings.MaximumHistoryEntriesPerEndpoint(...);
    })
    .AddSqlServerStorage(Configuration.GetConnectionString("..."));

later, additional configuration is in Configure method

Everything works when AddInMemoryStorage is used instead of AddSqlServerStorage. When AddSqlServerStorage is used, app crashes on startup, with

SqlException: Invalid object name 'Configurations'.

Sure, SQL tables are missing, but I cannot force [migration from nuget package to be applied to database.

Of course, I could copy/paste migration or create tables in database but I would like to skip that because of future changes and keeping code clean.

Can someone point me in right direction to solve this? Thanks

I've managed to solve it. Since migrations weren't applied to database, I ran them in Main like this.

var app = CreateHostBuilder(args).Build();
//run heaalthchecksui migrations
using (var scope = app.Services.CreateScope())
{
    var healthChecksDb = scope.ServiceProvider.GetRequiredService<HealthChecksDb>();
    healthChecksDb.Database.Migrate();
}

app.Run();

So, maybe that workouround could help someone with similar problem.
