XML deserialization with AOT

Is it possible to deserialize XML when using AOT? The default XmlSerializer relies on reflection and thus does not support AOT. Perhaps there are packages that utilize a source generator to implement a deserializer?...

Error handling through SQL or C#.

How common is it to handle errors and enforce constraints through SQL, with transactions and stored procedures, instead of with C# code? What is the best practice? Is there any performance gain or loss by choosing one over the other?...

✅ System.InvalidOperationException: No database provide has been configured for this DbContext

It is all about this newbie error

System.InvalidOperationException: No database provider has been configured for this DbContext. A provider can be configured by overriding the 'DbContext.OnConfiguring' method or by using 'AddDbContext' on the application service provider. If 'AddDbContext' is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.

✅ 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!
