Collection of Internet Computer Protocol (ICP) libraries for .NET/Blazor/Unity

• Agent - Library to communicate to and from the Internet Computer

• Candid - Library of Candid Encoding, Models and Helpers

• Client Generator - Client source code generator for ICP canisters

• Internet Identity (Experimental) - Internet Identity authenticater (experimental and not secure)

Note: WebGL/IL2CPP is not supported YET due to an issue with IL2CPP, working on it

• Download latest binaries for the agent: https://github.com/edjCase/ICP.NET/releases
• Extract .zip to a plugins folder in your Unity Assets: Assets/plugins/ICP.NET/
• If generating a client (see below), place the generated files into the scripts folder: Assets/scripts/MyClient
• Start coding 💻

• Prerequisite: Have .Net 6 installed (https://dotnet.microsoft.com/en-us/download/dotnet)

• Navigate to directory of .Net project

  cd {path/to/project}
  

• Add Agent nuget package to project

  dotnet add package EdjCase.ICP.Agent
  

• Install ClientGenerator

  dotnet tool install -g EdjCase.ICP.ClientGenerator
  

  This will allow a client to be automatically be generated for a canister. See ClientGenerator README for more details and advanced config

• Initialize ClientGenerator config (first run only)

  candid-client-generator init
  

  This will create a TOML config file in the directory that can be changed for more advanced options

• Update created config file candid-client.toml

  If using a canister id:

  namespace = "ProjectGovernance" # Base namespace to use
  output-directory = "./Clients" # Output directory
  
  [[clients]]
  name = "Governance" # Label of client to use
  type = "canister" # Indicates to make client from a canister id
  canister-id = "rrkah-fqaaa-aaaaa-aaaaq-cai" # Canister id to make client for

  If using a service definition file (.did)

  namespace = "ProjectGovernance" # Base namespace to use
  output-directory = "./Clients" # Output directory
  
  [[clients]]
  name = "Governance" # Label of client to use
  type = "file" # Indicates to make client from a service definition file
  file-path = "Governance.did" # File to use

  For all configuration options see ClientGenerator README for more details

• Generate Client

  candid-client-generator gen
  

  Will output C# file to the output directory specified in the config

• Use client in code

  var agent = new HttpAgent();
  Principal canisterId = Principal.FromText("rrkah-fqaaa-aaaaa-aaaaq-cai");
  var client = new GovernanceApiClient(agent, canisterId);
  OptionalValue<Sample.Shared.Governance.Models.ProposalInfo> proposalInfo = await client.GetProposalInfo(110174);
