The [[api-documentation:ILikeableContentType Plugin Type|ILikeableContentType]] interface provides support for liking content.

Why should I make my content likable?

If you would like users to provide feedback by demonstrating that they like your content then consider implementing the [[api-documentation:ILikeableContentType Plugin Type|ILikeableContentType]] within your [[api-documentation:IContentType Plugin Type|IContentType]] plugin.

Creating an ILikeableContentType plugin

The [[api-documentation:ILikeableContentType Plugin Type|ILikeableContentType]] is defined in the Telligent.Evolution.Extensibility.Content.Version1 namespace of Telligent.Evolution.Core.dll.

It is important to note that one or more Core Services can be implemented in the same [[api-documentation:IContentType Plugin Type|IContentType]] class.

Begin by defining whether a user can like your content. In this sample we limit liking to users that are not the author of the content. It is also a good practice to verify the content exist.

Similarly it is required to define who can unlike content. This logic can be similar to the CanLike method.

The SupportsLikes member returns whether any content of this content type can be liked. This property can simply return true.

public bool CanLike(Guid contentId, int userId)
{
    var content = LinksData.GetLink(contentId) as IContent;
    if (content == null) return false;

    return content.CreatedByUserId != userId;
}

public bool CanUnlike(Guid contentId, int userId)
{
    var content = LinksData.GetLink(contentId) as IContent;
    if (content == null) return false;

    return content.CreatedByUserId != userId;
}

public bool SupportsLikes
{
    get { return true; }
}

Here is the full sample.
