This repo contains a .NET Standard 2.0 implementation of the W3C Activity Streams specification.

A couple quick notes regarding this library:

• This is a work-in-progress and may not currently adhere 100% to the spec.
• There are likely to be breaking changes in the future as the implementation is refined - so use at your own risk.
• Significant overriding of the default Newtonsoft.Json JsonConverter was required to serialize/deserialize according to the JSON-LD/Activity Streams spec.
• The aforementioned customization likely negatively impact serialization/deserialization performance.
• This was written in brute-force manner. Goal was to get it to work broadly and then go back and improve performance.
• There are 320 unit tests validating the serialization/deserialization of this library against the examples provided on the Activity Streams vocabulary website. These tests are all green, but may not account for your scenarios. Please file a bug if you encounter something that should work but doesn't.

You must specify the ActivityStreamsConverter in the JsonSerializerSettings in order to property serialize/deserialize JSON content.

For example:

JsonSerializerSettings SerializerSettings = new JsonSerializerSettings()
{
    Converters = new List<JsonConverter>()
    {
        new ActivityStreamsConverter()
    }
};

var result = JsonConvert.DeserializeObject<ActivityStreamsObject>(json, SerializerSettings);

See the ActivityStreams.Primitives.Tests project for a full set of examples.

As always, pull requests are welcomed.
