We are pleased to announce the release of a cross-platform library for executing complex scripts in C# called FastScript .NET.
Libraries for executing complex scripts provide the ability to dynamically generate and execute code, which can be useful in various scenarios such as developing plugins, creating user scripts, and so on.
Working in Constrained Environments. FastScript .NET is built on the classic "lexer-parser-interpreter" model. It does not use compilation to machine code, allowing it to operate in environments where code generation is restricted (NativeAOT, iOS, WASM). Its performance is comparable to other solutions that use interpretation (such as Lua and JavaScript), although it is slower than compiled C# code.
C# as a Scripting Language. FastScript .NET has full integration with the .NET platform and allows the use of all libraries, frameworks, and APIs. A unified code base in C# for scripts eliminates the need to maintain code in multiple languages.
Compactness. The small size of the library (just 300 KB) makes it convenient to use even in resource-constrained projects without overloading the system.
Since version 2025.1.21 FastScript .NET is part of the WinForms, WPF, WEB, Mono and Avalonia packages. Our library is also part of Ultimate.NET solutions with all source codes.
In version 2025.2 the ability to use custom fonts has been added, functionality for Tasks, data sources, and preview service has been improved, the installation wizard has been redesigned.
No lançamento do Online Designer 2025.2 ficou disponível para você: suporte para relatórios VCL, criação de novos relatórios ao trabalhar com .NET WebReport, um novo menu de banda.
