Neo.Compiler.CSharp 3.10.0

Neo.Compiler.CSharp

The official C# compiler for Neo smart contracts. This compiler transforms C# code into NeoVM-compatible bytecode (.nef files) and generates contract manifests.

Features

• C# to NeoVM Compilation: Compile standard C# code to NeoVM bytecode
• Smart Contract Support: Full support for Neo smart contract development
• Optimization: Multiple optimization levels for bytecode efficiency
• Debug Information: Generate debug info for testing and debugging
• Artifact Generation: Auto-generate contract artifacts for testing

Installation

As a .NET Tool (Recommended)

dotnet tool install --global Neo.Compiler.CSharp

As a Package Reference

dotnet add package Neo.Compiler.CSharp

Usage

Command Line

# Compile a contract
nccs MyContract.csproj

# Compile with specific output
nccs MyContract.csproj -o ./output/

# Compile in debug mode
nccs MyContract.csproj --debug

# Generate artifacts
nccs MyContract.csproj --generate-artifacts source

# Print a static ABI and bytecode summary
nccs MyContract.csproj --print-abi

Note on --print-abi: This option prints script size, instruction count, ABI methods and events from the compiled contract.

MSBuild Integration
