Download .NET 8 Preview 6 (Offline Installers)


.NET 8 Preview 6 is now available to download. With this release, Microsoft has made a number of improvements and changes. Several improvements have been made to System.Text.Json, and Microsoft has also included an option validation source generator to reduce the startup overhead and improve the validation feature set.

What’s new in .NET 8 Preview 6

Improvements to System.Text.Json

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

  • Added caching support to the incremental generator, improving IDE performance in large projects.
  • Improved formatting of source-generated code, including fixes to a number of indentation issues.
  • Added a number of new diagnostic warnings.
  • Fixed a number of bugs related to accessibility modifier resolution.
  • Ensured that types of ignored or inaccessible properties are not included by the generator.
  • Fixed issues related to JsonNumberHandling support.
  • Fixed support for recursive collection types.
  • Fixed custom converter support for nullable structs.
  • Fixed a number of bugs in the compile-time attribute parsing implementation.
  • Added support for nesting JsonSerializerContext declarations within arbitrary type kinds.

Overloads added

The following overloads have been added for the said purpose:

  • ZipFile.CreateFromDirectory: It allows users to collect all the files included in a directory and zip them, then store the resulting zip file into the provided stream.
  • ZipFile.ExtractToDirectory: It allows users to provide a stream containing a zipped file and extract its contents into the filesystem.
