In this blog post, I’m going to cover the following topics:

• The new DateOnly and TimeOnly types
• Time Zone Conversion APIs
• Time Zone Display Names on Linux and macOS
• TimeZoneInfo.AdjustmentRule Improvements

For even more details, you can also refer to dotnet/runtime#45318 on GitHub. 

Minimal APIs will help new developers to build their first ASP.NET Core apps with less ceremony. 

.NET 6: Collections Improvements 

With the .NET 6 preview 4 we now have Ahead-Of-Time compilation for Blazor Wasm. This is an example of improved performance for one of my projects. 

This week during Build 2021, Microsoft issued .NET 6 Preview 4 and revealed that the final .NET 6 version will ship on November 9. 

In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace. Using these new types may align well with how databases allow similar data to be represented. Specifically, these types align well with the SQL Server date and time data types. 

EF Core 6.0 performance is now 70% faster on the industry-standard TechEmpower Fortunes benchmark, compared to 5.0.
