Bootstrap v5.1.1 has landed with a handful of bug fixes and documentation improvements. Following this release, we’ll be shipping another bugfix and docs update before moving onto additional new features. Keep reading for the highlights. 

Moments ago we published a new bugfix – please welcome ReSharper Ultimate 2019.2.3 . It delivers highly requested support for the .NET Core 3.0 release build, which was released earlier, for all the tools in the ReSharper Ultimate family!

.NET 8 RC1 is now available. This is our first of two release candidates. This release includes a new AOT mode for both Android and WASM, System.Text.Json improvements, and Azure Managed Identity support for containers. Now is great time to pick up and test .NET 8 if you haven’t yet.  

We’re shipping our latest patch release today to fix a handful of bugs in Bootstrap 4. While our focus remains on v5’s second alpha release (coming in the next couple weeks), we want to keep v4 as stable and reliable as possible. 

Version 10.0.0 is here! This is a major release that spans the entire platform, including the framework, Angular Material, and the CLI. This release is smaller than typical; it has only been 4 months since we released version 9.0 of Angular. 

Today we are glad to announce an alpha release of SignalR for ASP.NET Core 2.0. This is the first official release of a new SignalR that is compatible with ASP.NET Core. It consists of a server component, a .NET client targeting .NET Standard 2.0 and a JavaScript/TypeScript client. 

Performance Improvements in .NET 9

Each year, summer arrives to find me daunted and excited to write about the performance improvements in the upcoming release of .NET. “Daunted,” because these posts, covering .NET 8, .NET 7, .NET 6, .NET 5, .NET Core 3.0, .NET Core 2.1, and .NET Core 2.0, have garnered a bit of a reputation I want to ensure the next iteration lives up to. And “excited,” because there’s such an abundance of material to cover due to just how much goodness has been packed into the next .NET release, I struggle to get it all written down as quickly as my thoughts whirl.

1. Support for UPDATE FROM following the PostgreSQL syntax.

2. Increase the maximum size of database files to 281 TB.

To reduce allocations and memory usage when serializing Json.NET 8.0 adds a new IArrayPool interface. Json.NET is already very lean when it comes to allocations, working with raw characters on array buffers instead of allocated strings, but those buffers can easily grow large, and a new buffer is created each time JSON is read or written. IArrayPool allows array buffers to be reused, similar to connection pooling with a database, or thread pooling in .NET.
