DateOnlyTimeOnlyInt128UInt128Half

JSON Contract Customization

JSON contract customization gives the user more control over what and how types are serialized or deserialized. Developers previously had trouble doing so because they either either came from an external library or it would greatly pollute the code but need to make some changes that influence serialization.

Changes to System.Formats.Tar

Systems.Formats.Tar was first released with .NET 7 preview 4. Now, Microsoft is making a few changes to it in the following areas:

Global Extended Attributes specialized classThe TarFormat enum was renamed to TarEntryFormat as an entry format, and not archive format.Several writing and reading changes have been implemented which you can read here.

Closing Words

The last preview release for .NET 7, which was .NET 7 Preview 5, was released nearly 3 weeks ago. This indicates that Microsoft is working round the clock to improve the .NET platform and make the necessary changes before launching it publicly. That said, since this release is still in its preview, we do not recommend that you install it in a production environment. Rather, we suggest you use it in test environments only and check out the new improvements and compatibility with your existing and new applications. Also see:
