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…
Starting with .NET 8, the JsonSerializerOptions class features a new TypeInfoResolverChain property in addition to the existing TypeInfoResolver property. With this new property, you are no longer required to specify all the resolvers in the same place, instead, you can add them later as needed. Let’s look at an example: Besides adding new type resolvers…
Files opened or saved using WPF’s file dialogs (OpenFileDialog, SaveFileDialog or OpenFolderDialog) are by default added to the Windows Explorer’s recent files list and can also impact the Recommended section of the Start Menu in Windows 11. To disable this behavior, you can set AddToRecent to false on your dialog before calling the ShowDialog() method….
A new ClientGuid property, introduced with .NET 8, allows you to uniquely identify dialogs such as the OpenFileDialog and the OpenFolderDialog, with the purpose of storing state – such as window size, position and last used folder – separately per dialog. To benefit from this behavior, configure the ClientGuid of your dialog to a known…
Interceptors are an experimental compiler feature introduced in .NET 8, meaning it may change or be removed in a future release of the framework. To see what else is new in .NET 8, check out our What’s new in .NET 8 page. To enable the feature, you’ll need to turn on a feature flag by…
