“As a VB.NET developer, Mercury gives me access to so many platforms that I didn't have before.”

— Avonelle Lovhaug

Write VB-Compatible Code, for Any Platform

With Mercury, you can build your existing VB.NET projects, and leverage your Visual Basic™ language experience to write code for modern target platforms across the full Elements family.

That includes desktop apps, web services, mobile apps, native operating-system targets, and WebAssembly, all using the same familiar language shape.

.NET

.NET, .NET Core, Mono, and ASP.NET Core.

Java

The Java VM, and any device that runs Java code.

Android

Android through both the Java-based SDK and the CPU-native NDK.

Cocoa

iOS, macOS, tvOS, and watchOS with native Cocoa APIs.

Native OS Targets

Windows and Linux, compiled to CPU-native applications and tools.

WebAssembly

WebAssembly for web browsers, Node.js, and modern web runtimes.

Sophisticated IDEs for Windows and Mac

The Mercury language is deeply integrated into the Elements development environments. Develop projects in Water on Windows or Fire on Mac, with project templates, code completion, integrated debugging for all platforms, and many other development features.

Of course, Mercury also integrates into Visual Studio™ 2017, 2019, 2022 and 2026.

Fire for Mac

A native Mac IDE for the full Elements toolchain.

Water for Windows

A fast, focused Windows IDE for Elements projects.

Visual Studio

Work with Mercury inside Microsoft's powerful IDE on Windows.

Mix Mercury Code With Other Languages

With Elements, all languages are created equal. Even within the same project, you can mix Mercury, C#, Swift, Java, Oxygene, and Go when that makes your codebase clearer or lets you reuse existing work.

Oxygene

Silver

Iodine

Ecosystem

Mercury, like all Elements languages, comes with an extensive toolchain: IDEs, compiler integration, build tasks, debugging, deployment, and the final packaging pieces you need to get real apps out the door.

It also fits into each target platform's existing ecosystem rather than asking you to step outside it.

Apple Platforms

Use Cocoa APIs on Mac, iOS, watchOS, and tvOS, together with .xib files, storyboards, and asset catalogs.

Android and Java

Work with Java APIs, dex'ing, apk packaging, and external Gradle packages.

.NET

Use the .NET framework library, third-party DLLs, NuGet packages, desktop .NET Framework, .NET Core, or Mono.

Language Extensions

As part of the Elements family, Mercury automatically inherits a lot of additional special features. We are also looking at the VBLang community for historical requests, and have already implemented many of them, with plans for more.
