Mongo Migration dependency before Background service kicks off - .NET Core

[rajurh]

Hello, I am working on a .NET 6 project that includes a background service. I have configured the migration in the startup as shown below. However, I have a problem: the background service tries to access the database before it is ready. This happens when the migration takes longer than usual to set up MongoDB. How can I ensure that the background service waits for the migration to finish before performing any database operations?

services
.AddMigration(new MongoMigrationSettings
{
Database = "blabla",
ConnectionString = config.GetConnectionString("MongoDb"),
DatabaseMigrationVersion = new DocumentVersion(1, 0, 0)
});

Create an extension
public static void UseMongoDbMigrations(this IApplicationBuilder builder)
{
try
{
using (var scope = builder.ApplicationServices.CreateScope())
{
var services = scope.ServiceProvider;
var migrationService = services.GetRequiredService();

        migrationService.Run();
    }
}
catch (Exception ex)
{
    // .... Some error handling ?
}

}

Then pop this in program.cs straight after the line var app = builder.Build();
app.UseMongoDbMigrations();
