New in .NET 8 Preview 7

Improvements to System.Text.Json

The following improvements have been made to the System.Text.Json source generator

  • JsonSourceGenerationOptionsAttribute now has feature parity with the JsonSerializerOptions
  • Built-in support for Memory<T>/ReadOnlyMemory<T>
  • Built-in support for HalfInt128 and UInt128 numeric types
  • Extending JsonIncludeAttribute and JsonConstructorAttribute to non-public members
  • IJsonTypeInfoResolver.WithAddedModifier extension method
  • Additional JsonNode functionality

Keyed services support in Microsoft.Extensions.DependencyInjection

Keys allow for scoping of registration and consumption of services. Microsoft has now added support to DI abstractions, as well as an implementation in the built-in Microsoft.Extensions.DependencyInjection.

HTTPS Proxy

HttpClient now supports the usage of an HTTPS proxy. This might be a huge boost in terms of defense against interception assaults.

HTTPS is widely used and is essentially a must for all open internet websites. However, there are many situations in which using raw (unencrypted) HTTP is a good idea. These situations frequently work nicely with a proxy. An HTTPS proxy creates a secure route for communication between the client and the proxy, guaranteeing total confidentiality.

HybridGlobalization mode on iOS/tvOS/MacCatalyst platforms

The creation of InvariantGlobalization mode was done to do rid of the reliance on ICU (which has a high size cost). The fact that most globalization functionality is no longer supported is a key trade-off of this mode. This new feature strikes a balance between keeping globalization functionality while considerably shrinking size (34% decrease).

Ending thoughts

.NET 8 will replace .NET 6 in the Long Term Support (LTS) channel which is said to be supported for 3 years after its initial release. Currently, its preview version is available to download which is now Preview 7. Note that no more previewing will be released. Instead, Microsoft will now publish Release Candidates as the final, stable release approach.

That said, we suggest that you remain on the stable releases for your production environment while continuing to test out the latest features and improvements in an isolated environment within .NET 8.
