ads for multi-platform avalonia (or Android at least xD)
Hi!, I'm very very new to all this xD and while I worked with WPF, this is my first time uploading something...
So, I've made this Multiplatform App in AvaloniaUI, and I am focusing right now on the Android side of it, I'm about to publish (today hopefully) the app in the Play Store, but I have no idea how to add ads to it... I was thinking on a simple banner somewhere in the bottom of the app, so I can pay for servers/services and the app would be self maintained, but... all the explanations, tutorials, etc are targeted for Android specific platforms, which, I never used, so while Avalonia has access to this code implementations, I have no idea what half of what I'm reading means...
As an example, admob has an SDK... in step one of the guide it sais "In your Gradle settings file, include the Google's Maven repository and Maven central repository" and then there are two explanations that say "Kotlin" and "Groovy"... I have no idea what ANY of this means, I tried finding what Gradle is, and seems like it is an actual file, which I also don't have in my project for some reason, I have no idea how to get or access those repositories, it mentions... I'm really lost, I've been trying to do this for a while now.. first trying to find an ad service which used paypal, cos I'm not from the US, so paypal was the best way of managing the exchange from dollars to pesos by myself, but I can't understand any of the different services explanations, they don't seem to focus on c# implementations on their mini guides...

Markdown editor without separate preview
Hey, so I'm planing on creating either a WPF or an Avalonia application, that serves as markdown editor (prefered avalonia, because of cross plattform).
The markdown editor should be inspired by Obsidian or Notion, meaning you don't have a separate preview, but instead get the markdown rendered directly "block wise" in the same area where you can type.
I first thought of having a textbox and whenever you press
enter
a new textblock gets rendered with the markdown converted to html for example. When you click on this textblock it gets converted to an editable textbox again.
However with this approach I would loose all the features a single textbox has, like ctrl+z etc.
Anybody has some idea how I could manage the live rendering of markdown?...App Insights vs Azure Monitor (OpenTelemetry)
I am wanting to know what the difference is here, I was reading this document here. and was just trying to make sure I was understanding this correctly.

Custom Memory Allocator
I need to manage millions of rather long lived (minutes to weeks) byte arrays that contain hundreds of KBs in memory. I need to be able to release the arrays if the memory pressure is too high and then reuse the RAM for arrays with other sizes. It is an in-memory database , which contains hot data from multiple TB of disk storage. Since a lot of IO is involved a lot of async functions are called and I can not make sure that the thread allocating is also the thread releasing memory. I think doing...

Hey, new to C# and wrapping my head around following MVVM. Can someone help me understand how the button knows what to do here?

question on complexity of a game

What project type to choose, VS
Hello, I'm very new to C#, currently studying it on school, and I can't choose the right project type for my work.
We have 12 different exercises that need to be done in one project, I've tried doing a Console App project but since I need multiple files, I need multiply for loops and mains and it doesn't let me do more than one.
I've tried a Class project as well but it doesn't debug because its a library.
What project should I choose?...
