CaSS Docs

# C#

Thios guide will walk you through the basics of using some features of the CaSS Library in C#.

Links for distributions of the library may be found in the Links page inside the developer guide.

WARNING

Currently, there is no formal CASS library for C#. If you would like to contribute or begin developing one, see the contributor section of this guide.

# JavaScript Interpreter

Several JavaScript interpreters have been written for C#, however, it is unclear whether appropriate bindings exist. In theory, the CASS Libraries are compatible with any JavaScript environment, given access to functions like JQuery’s $.ajax call.

This type of integration is desirable for continued expansion of supported languages for CASS.

If this is something you would like to pursue, please get in touch with the lead developer: fritz.ray@eduworks.com

# Consuming Data

If you are only intending to consume CASS data, the path is much simpler.

  1. Create a helper method and fetch resources
public async Task<JsonObject> httpGetJsonObject(String url) {
    System.Net.Http.HttpClient hc = new System.Net.Http.HttpClient();
    String s = await hc.GetStringAsync(url);
    JsonObject root = Windows.Data.Json.JsonValue.Parse(s).GetObject();
    return root;
}
  1. Retrieve frameworks and competencies
JsonObject obj = await c.httpGetJsonObject("https://sandbox.cassproject.org/api/custom/data/schema.cassproject.org.0.2.Framework/ce4c0e41-f24c-407d-95af-047bfee429bf");
String foo = obj.GetNamedString("name");
JsonObject obj2 = await c.httpGetJsonObject(obj.GetNamedArray("competency")[0].GetString());
foo += "\n" + obj2.GetNamedString("name");
  1. If you need to generate an RSA public/private keypair in C#, use NuGet to download a package called BouncyCastle
using Org.BouncyCastle.Crypto;
using Org.BouncyCastle.Crypto.Generators;
using Org.BouncyCastle.OpenSsl;
using Org.BouncyCastle.Security;

// ...

RsaKeyPairGenerator r = new RsaKeyPairGenerator();
r.Init(new KeyGenerationParameters(new SecureRandom(), 2048));
AsymmetricCipherKeyPair keys = r.GenerateKeyPair();
TextWriter textWriter = new StringWriter();
PemWriter pemWriter = new PemWriter(textWriter);
pemWriter.WriteObject(keys.Private);
pemWriter.Writer.Flush();

string privateKey = textWriter.ToString();
