Where do I put startup work in a Blazor app?

Hi all;

In my Blazor server app, when it starts up, I want to create any Azure Storage BLOB containers that I expect that don't exist yet. Where is the appropriate place to put code like this?

Is it ok to put it at the end of the Program.cs main() method? And if so, how do I get an instance of the service I need to accomplish this there? Do I call:

app.Services.GetService<IMyService>();

thanks - dave

In the section where you are adding services, you should create the container and inject the container access.

if you created a container access wrapper, it could also create in first access. Just inject the connection settings.

That would be in Program.cs. Is it considered OK to put code like this in that location?

I can't do it in the container access wrapper because the first use of that could be 7 (soon more) different places. I'm trying to avoid having to check every time I access the container.
