This is quite a common issue that usually occurs in flutter release builds. More often than not the issue is caused by ProGuard stripping away some required APIs at build time, leading to missing implementation exceptions such as the one below. That being said, there are actually multiple possible causes to this issue, as such…
Starting with C# 12, a new ExperimentalAttribute is introduced allowing you to mark types, methods, properties or assemblies as being experimental features. This will trigger a compiler warning during usage which can be disabled using a #pragma tag. The Experimental attribute requires a diagnosticId parameter to be passed in the constructor. That diagnostic ID will…
The ref readonly modifier enables a more transparent way of passing read-only references to a method. Passing of readonly references was already possible in C# by using the in modifier ever since version 7.2, but that syntax had some limitations, or rather too little constraints. So how does the new modifier work? Let’s assume the…
This is quite a frequent question. You’ve got: But what comes after decillion? The answer is: undecillion. An undecillion, has 36 zeroes. That’s a lot of zeroes: 1,000,000,000,000,000,000,000,000,000,000,000. But there’s more. If you look past the undecillion, you’ve got: Interested in how long it would take a PC to count to a trillion? Check out this…
The easiest way to shuffle an array in C# is using Random.Shuffle. This method has been introduced in .NET 8 and works both with arrays and spans. The suffling is done in-place (the existing array/span is modified, as opposed to creating a new one and leaving the source unchanged). In terms of signatures, we’ve got:…
There are some situations in which creating a whole new IJsonTypeInfoResolver will seem overkill, when the default (or any other already defined) type info serializer could do the job with only one or two small modifications. Until now, you could play with the DefaultJsonTypeInfoResolver.Modifiers property for the default type info resolver, but you didn’t have…
A new extension method – GetFromJsonAsAsyncEnumerable<T> – has been added to the HttpClient part of .NET 8. This new mthod will take the response body JSON and deserialize it into an async enumerable operation. The complete signature of the extension method is as follows: Let’s take a look at how to use it. First thing…
Part of .NET 8, JsonNode and JsonArray get a few new additions to their API. We’ve already covered deep copy and deep equality in an earlier article, but there’s more. GetValueKind Returns the JsonValueKind of the current instance. GetPropertyName Returns property name of the current node from the parent object. Throws an InvalidOperationException if the…
Starting with .NET 8, several new methods have been added to the JsonNode class to help with the deep cloning of nodes and checking whether they are equal or not. The DeepClone() method will create and return a deep clone of the current node and all of its descendants. On the other hand, DeepEquals() will…
Starting with .NET 8 you can disable the default reflection-based serializer that comes with System.Text.Json. This can be useful in trimmed and native AOT applications where you don’t want to include the reflection components in your build. You can enable this feature by setting the JsonSerializerIsReflectionEnabledByDefault property to false in your .csproj file. As a…
If you follow YouTube’s guides to deleting a channel, you might find that in your case the Remove YouTube content is missing altogether. This seems to be the case with newer account, but no worries there’s a workaround. Go to YouTube Studio instead. Go to Settings > Channel > Advanced settings and scroll to the…
A NullReferenceException is a common runtime error which occurs when your code tries to access or manipulate an object or a member of an object, but the object reference is currently set to null (meaning it doesn’t reference any valid object in memory). In other words, you’re trying to perform an operation on something that…
