Extensibility Studio 5.0 Highlights

Installation improvements, Code Editor new features and TypeScript/JavaScript support for Form Designer.
1 June 2019

We have released a new major version of AlterNET Extensibility Studio, focusing on installation improvements, Code Editor new features, and TypeScript/JavaScript support for Form Designer.

Visual Studio 2019 support and NuGet distribution

AlterNET Extensibility Studio is now compatible with all Visual Studio versions starting from Visual Studio 2013. On top of that, we have published our core libraries to nuget.org:

Due to the changes, we had to make to support NuGet package distribution, the minimum requirements for .NET Framework were raised to 4.5.2. These packages also contain .NET 4.6 targets which allow using the latest versions of Microsoft Code Analysis packages (Roslyn) that support C# 7 language features.

TypeScript/JavaScript support for Windows Form Designer

Form Designer assembly is now split into the core Form Designer library and language extensions that provide language services related to the form saving/loading and handling events. On top of C#/Visual Basic, we now support these services for TypeScript/JavaScript.

Similarly, we have split the ScriptDebugger assembly into a base script debugger that provides debugging interfaces used by script debugger widgets. These interfaces are now implemented independently for C#/Visual Basic debugging and TypeScript/JavaScript debugging.

Code Editor improvements

We have reworked our Search/Replace dialogs to match the latest ones in the latest Visual Studio and added filtering and search highlighting capabilities to code completion windows.

Code Editor improvements

Other improvements include the automatic generation of type definition files for TypeScript, providing information for TypeScript editing and execution, and bug fixes across all our products.
