NEO Blockchain Quick Start Guide for .NET Developers


NEO Blockchain C# Developers Center of Excellence

The neo-csharpcoe project is an "umbrella" project for several initiatives related to providing tools and libraries (code), frameworks, how-to documentation, and best practices for enterprise application development using .NET/C#, C#.NEO and the NEO Blockchain software platform.

The neo-csharpcoe is an independent, free, open source project that is 100% community-supported by people like yourself through your contributions of time, energy, passion, promotion, and donations.

To learn more about contributing to the neo-csharpcoe, click here.


The purpose of this document is to enable .NET developers who are brand new to NEO Blockchain technology to create a useful NEO development environment and get it up and running in as little time as possible.

This document is specifically targeted at .NET developers and architects.


In addition, when the first version of the document was written (February 2018), you will also need to have an early adopters mind set. It's the early days. You'll be downloading the code for most of the developer tools (aside from Visual Studio) and compiling them yourself. It may not always be fun but I promise it will certainly be rewarding in the end.


  • Ensure you have a working and properly configured NEO development environment up and running in as short a time as possible
  • Enable to create, deploy and test your first NEO smart contract written in C# (using the HelloWorld sample)


  • Provide reliable documentation: timely, accurate, visual, and complete
  • Save as much of a person's time as possible
  • Use open source software whenever possible


  • Need in the NEO .NET developer community to have concise and easy-to-follow documentation to enable people to get up to speed developing NEO smart contracts in as short a time as possible
