Best Way To Load and Cache Scoped Data?

I am using MediatR, so scoped services essentially live the lifetime of the MediatR request. Given that, I want to load configuration from a database if not loaded (using Entity Framework), then cache the returned data, as it is used multiple times for the request. What is the best way to go about this? This is my current code, but this is blocking and I would think could cause performance issues. ...

Compiling C# without Visual Studio

I'm new to C# and I understood that if i want to compile code without Visual Studio i need to use Roslyn, but on github it marks the latest release as .NET 6.0. Is there no way to compile C# code with .NET 8.0 as it is the latest LTS release? Visual Studio is very heavy, especially since i don't intend to use C# for big projects and my system isn't too performant.

MySqlException: Field 'CreatedOnUtc' doesn't have a default value

So I have been creating a very simple ASP.NET Core application lately with a simple mariaDB configuration and nginx Once the dotnet run has been typed, a web app pops up on Chrome prompting me to enter login credentials. As the combination of root-root (for both of username and password) is not allowed there, I opted to create a new user. The web app now prompted me to create brand new credentials (email, password, username). Once those have been entered and the submit button has been hit, the following error got triggered...

✅ Can't infer type arguments from usage

I was looking into writing an extension method to Flatten nested collections, as I always forget that SelectMany(i => i) exists (and also personally think it's ugly/non-intuitive). Said method looks like so: ```cs public static IEnumerable<TValue> Flatten<TOuter, TInner, TValue>(this TOuter items) where TOuter : IEnumerable<TInner> where TInner : IEnumerable<TValue>...

Increased I/O utilization after new version deployment

Hello, maybe someone will have some ideas, because I'm running out of them. New application version was deployed to production and we noticed increased C and D disk utilization. Reads/writes remains the same, but utilization skyrocketed. Couple days of not paying much attention we got total VM crash, CPU hit 100% and everything froze. Not sure about previous % Time in GC statistics, but current one looks awufly high. Turning service off does not reduce utilization, tried waiting 30min. Only server reboot helps to fix it. ...
