NEO Persistable Classes (NPC) Platform 2.0 - An Efficient Entity-based Platform for enterprise distributed application development using .NET/C#, C#.NEO and the NEO Blockchain

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.

• NEO Persistable Classes
• Long name: NEO Persistable Class (NPC) Platform 2.0
• Byline: An Efficient Entity-based Platform for enterprise distributed application development using .NET/C#, C#.NEO and the NEO Blockchain

• A multi-user whiteboard dApp built with the NEO Persistable Classes (NPC) Platform that runs on the NEO Blockchain.
• An advanced proof-of-concept distributed application (dApp) for the NEO Persistable Classes (NPC) Entity-based dApp (e-dApp) Platform.

More information on NeoDraw can be found here.

As a neo-csharpcoe compliant platform, the NPC-edApp platform includes a full suite of tools and libraries (code), frameworks how-to documentation, and best practices for enterprise application development using .NET/C#, C#.NEO, and the NEO Blockchain:

NPCdApp 1.0 is a C#.NEO smart contract dApp built for the CoZ dApp Competition #2 (closing date: February 24, 2018) to demonstrate NPC’s:

• Unique object-oriented programming style for C#.NEO smart contract development
• Layered entity persistence model

• Script Hash: 0x7074acf3f06dd3f456e11053ebf61c5b04b07ebc (testnet)

• public static object Main(string operation, params object[] args) (link to source)

• win-gui parameter types: 0710

There are a number of different levels when it comes to applying the NPC Framework to classes in C#.NPC. There are:

• NPC Level 0 Basic
• NPC Level 1 Managed
• NPC Level 2 Persistable
• NPC Level 3 Deletable (Bury/Tombstone)
• NPC Level 4 Collectable
• NPC Level 5 Extendible (roadmap)
• NPC Level 6 Authorized (roadmap)
• NPC Level 7 Optimized (roadmap)
