New C# dev struggling to configure for linux

Hey! I'm in a course for C# development right now, but I'm having some issues configuring my machine for development. I'm currently on Manjaro and I'm using Rider, but I'm attempting to get dotnet 6.0 and 9.0 installed on my machine (some of my course material/the repos I work from are older and target 6.0, but the coursework is for 9.0) -- I'm just having a bit of trouble getting everything configured as it should be and I'd appreciate a guiding hand in getting everything set up properly for development on linux. Thanks!!...

How long does it take to learn C# from scratch?

During my studies of computer science I’m expected to learn C# in order to use for a project I’ll start making later on this year, I’ve only had experience with the programming language python. Considering I have a reasonable amount of free time I want to be able to master C# and some other programming languages to see where it can take me.

How do caller information attributes fit into structured logging?

It seems like the standard Microsoft Ilogger takes structured arguments with as params object[] , making it hard to combine it with caller attributes such as [CallerMemberName] . I know that caller information can be added for source-generated logging with [LoggerMessage] or [LogProperties] attributes on an ad-hoc basis, but I'm looking for an infrastructural solution. How are you dealing with injecting caller information at scale in your code base? I thought creating an interface...

✅ Can't run my code in Visual studios

So basically i'm a complete begginer when it comes to coding and i'm currently trying to use visual studios. Yet, when i try to run my code using f5 nothing happens. When i try to run it using the green button that's supposed to make it run all that pops up is a window that shows a bunch of my files. The window is titled "attach to process" so i'm guessing that i have to attach a process to my project however i have no idea how to do that or what a process even is. So, how do i make my code run? This might not be the right place to ask about visual studios but i didn't know where else to go. Thank u in advance....

Alternative to FluentAssertions

Earlier this year fluentassertion went to a paid license model. What are some assertion libraries which are similar in assertion style and features, but free? One feature we use quite a bit is the object comparer (.BeEquivelantTo()) so whatever we swap to, should ideally support object graph comparison. Let me hear what you guys use / think would be a good free replacement 🙂...

How to resolve this unmanaged memory leak?

I've written a small mpv renderer for avalonia using opengl:

So far everything seems to work except when i'm done and call dispose almost no memory involved with the renderer is released even though i destroy the native pointers in a safe way. I'm not sure what i am missing. Any help would be appreciated. For more context, the whole repo is here and readily reproducible: https:///www.github.com/saverinonrails/avaloniampv...
