Disposing dbContext with dependency injection

Hi! I am developing an Avalonia UI app. I am displaying there some data, which is stored in the sqlite database. The data - rows in that matter - can be deleted or added, but once they are there - they are not modified (at least for now ;)). I have a factory which gets data from db and then creates a view model passing there the data (and few other things). The factory itself I've registered in service container as a singleton and dbContext as a transient. dbContext is injected into the factory. As I am not tracking entities changes and not adding or deleting data in that place, I've configured the context with optionsBuilder.UseQueryTrackingBehavior(QueryTrackingBehavior.NoTracking);....

Issue referencing a library within a cloned GitHub project

I have been struggling to reference the namespace "DirectXTex" in: https://github.com/Neodymium146/gta-toolkit/blob/master/RageLib/Helpers/DDSIO.cs From what I see/know.

Database In ASP.Net Core

Hello! So basically we all know when we create a SQL Database in Visual Studio Community with EF and SQLServer and we can store data there. My question is this: when we add the app to a website like Heroku or a Hosting App in order to publish it to the web, does the database with all the data gets added too or is there a separate process for that? Thanks!
