Substrate is a fully-developed .NET SDK for editing Minecraft worlds. Substrate provides high- and low-level APIs for manipulating Alpha and Beta-compatible maps and player data. Substrate is developed in C# as a CLS-compliant assembly, and example code is provided for both C# and VB.NET. A brief list of Substrate's capabilities are:

• Alpha and Beta map compatibility
• Separate block, chunk, and region views
• Global and local coordinate systems
• Automatic and manual light recalculation
• Automatic and manual fluid recalculation
• Automatic chunk cache management
• Automatic TileEntity and Heightmap consistency
• Entity editing support
• Player editing support
• Level data editing support
• Edit existing worlds or create new ones
• Schematic import and export
• Low-level APIs for NBT reading, writing, and validation

Most of the Substrate APIs are fully documented, including a compiled API reference document and XML documentation for Intellisense. A number of different example projects are provided in C# and VB.NET.

Substrate is compatible with .NET Framework 2.0 or higher and Mono, and should be compatible with any CLI language. All feedback is welcome: open an Issue or respond in our Minecraft Forums thread.
