✅ doubts about migrations

what's bothering me: every time we do a migration on our main service we have 8K+ lines more to commit in the project (which btw means that for example in the vs search i have to exclude migrations path - thing that took ages because it didn't work - or it's useless) it's not a big deal di per se, but i find it kinda silly that project is what, ~150K loc, and we have 1+ M loc of migrations (around 100 tables (i'm working on isolating some parts, but i don't know if/when that'll happen) and almost 400 migrations) because every migration (ef core) does a new snapshot so is this how it's supposed to be? is it not? would i be better off moving migrations to another solution? is there a way to save some code?...

How do I create my own file extension?

Help please. In short: I need to create my own file extension, for example levelData.ldat, and so that only the program can access this file (read and modify it), but not the user in any case

.NET 8.0, PostgreSql and left over Idle sessions

I have a .NET 8 webapp and we've done a dumb and manually handled postgres database connections throughout our classes.. I think this could be the root of my problems really... We new up connections and pass the connection around through our various classes, we end up sometimes passing the same connection down 2,3,4 times, re-using it, with the final disposal being quite some time later... making it hard to follow where idle connections are even coming from. One clue might be that the Idle connections don't even have a query associated with them... (making it really hard to pinpoint where they are coming from). I still feel like a noob C# developer (about 2 yr) and haven't touched things like dependency injection yet.. does anyone here know of any good resources for setting up and managing postgres DB connections that get implemented across many classes? My issues is we have leaky connections, even though i've been careful to go through the entire project and wrap ever instance of NpgsqlConnection/NpgsqlCommand in using statements and (tried to) implement the IDisposable interface for each class using the postgres connections. But i'm still finding some leaky connections/sessions building up over time....

I need help implementing recursion in a general way

Help I realise you need to understand recursion to understand the rest of DSA like graphs etc but I'm not fully confident So I know that recursion uses a base case and a recursive case but how can I come up with these on the spot like nothing because you can turn any for loop or while loop into a recursive function?...

do defined route added to the the routes table when the app.Run() executed or before?

I previously asked about the roles of UseRouting and UseEndpoints, and the answer was that UseRouting matches incoming requests against predefined routes in the route table. My question now is about the route table itself: Are the routes added to the route table before or after app.Run() is executed? I’m asking this because, during a debugging session, the application seems to go through the middleware pipeline step by step, executing each middleware until app.Run() is reached, after which the p...

Custom Logger

Hi all, been trying to figure this out for a bit now but I'm not sure what's happening. I am writing a custom extension for Microsoft.Extensions.Logging to write to a Sql Server database with a particular schema. However, I'd opted to make it as generic as possible. After doing a lot of research, I've created a DbLoggingProvider and a MSSqlDatabaseLogger. The logging provider creates new instances of the database logger, as expected, and the database logger expects an instance of a type implementing ILogAgent which it forwards its log method to. The log agent is responsible for performing the database-specific operations. However, when doing unit tests, I am unable to prove that logging works. In fact, it appears to not. Take the following test....

Failing to recompile Unity.SourceGenerators as type "Enumerator" isn't a valid name or namespace.

Hello! I have been trying to recompile Unity.SourceGenerators so I can reimplement it in a solution, but the class TypeNameHelper.cs has a field where it attempts to initialize a class/type "Enumerator", but VS can't find it. I've tried the potential solutions, such as IEnumerator, enum, and IEnumerable name changes, as well as some formatting changes, but nothing seems to resolve it. My main question is is this just a missing class/dependency I should have in the Unity.SourceGenerators project, or is it something that's just an older class that's now been replaced with something else? Picture attached, let me know if you need any more info, thanks!...
