Here’s a look at some of the new features.

SyntaxEditor

Intra-Text Adornment Location

Elapsed time adornment shown at the end of a line

Intra-text adornments can now optionally appear after the tagged text range instead of before. This allows for features such as AI suggestions or contextual information to appear past the last character in a line.

Outlining Margin Modernization

Outlining margin glyph updates

The rendering of the outlining margin has been modernized and now matches the latest Visual Studio code editor appearance.

SyntaxEditor .NET Languages Add-on

C# 13 Syntax Support

Parameters showing in IntelliPrompt from C# primary constructors

The .NET Languages Add-on’s C# parser previously only supported C# 9 syntax. The updates in this version now support all C# features up to and including C# 13.

C# Interpolated String Expressions

IntelliPrompt working in interpolated string expressions

The .NET Languages Add-on’s C# syntax language now syntax highlights interpolated string expressions. It also fully supports IntelliPrompt features within the expressions, making interpolated string editing much better.

Miscellaneous

.NET Requirements

All assemblies now have a target for .NET 8. Prior .NET Core 3.1 targets were updated to .NET 6 instead, which can be used by those not yet moving to .NET 8.
