Asynchronous batch processing (queue) in C#
Hey guys, I have some batches to process and to do so I have to send each of my batches to external APi to process. I have no experience with async programming so I simplified it a bit by using Parallel.Foreach that create thread/task for each API calling and waiting for response. The reason I dont want to call API synchronously Is that processing of one batch can take a one sec or 30min (max). With the Parallel.Foreach solution it looks it works fine but form what I read on internet it's not a good approach so I want to implement kind of async queue that will take a few items from my collection of batches starts processing and after some of them is finished replace it with another etc. I tried to came up with something using ChatGPT but it only process specified number of batches (3 in my case) and than it does nothing but even if the code is short there are lot's of new concepts for me so I have no idea how to fixed this. ```public async Task ProcessBatchQueueAsync(IEnumerable<int> batchIds)
{
var semaphore = new SemaphoreSlim(3);
var tasks = new List<Task>();

Class separation
I've got a console app that does a lot of heavy lifting. Let's say it's got a service class (that performs http calls) as a dependency and the main class is calling it a multitude of times. The unit testing for the main class of the console app is becoming huge. Is it a good approach to just create a class that aggregates all the calls to the service class?
In App Billing purchased fetching on mac os causes restore failed issue sometimes
I am trying to use the InAppBilling plugin library by james montemagno (https://github.com/jamesmontemagno/InAppBillingPlugin) in an avalonia program. I have setup subscription and well configured the settings, info.plist and entitlements for this purpose.
But the problem is, the library, when fetching from app store, it sometimes work and sometimes says failed due to restore issue, which I think means that it was not able to connect to app store and fetch purchases.. I saw a solution saying that we just have to keep trying in a loop, but still the error is not clearing. It particularly happens when I am trying to fetch purchased subscriptions list to check if the user has purchased our product or not.
Has anyone ever faced this and found solution for it? Looking forward for any help. Thank you!...

This makes it possible that enum is serialized to string when the request comes in.
Is this evaluated on each request, or only once at compile time?...
