Question

For example I have the following class:

public class PublishFacebookOpenGraphActionRequest
{
    public FacebookOpenGraphActions Action { get; private set; }
    public FacebookOpenGraphObjects ObjectType { get; private set; }
    public Uri Url { get; private set; }
    public Uri Image { get; private set; }
}

And I would like to be able to generate something like this from the current set of properties:

public class PublishFacebookOpenGraphAction
{
    public FacebookOpenGraphActions Action { get; private set; }
    public FacebookOpenGraphObjects ObjectType { get; private set; }
    public Uri Url { get; private set; }
    public Uri Image { get; private set; }

    public PublishFacebookOpenGraphAction WithAction(FacebookOpenGraphActions action)
    {
        this.Action = action;
        return this;
    }

    public PublishFacebookOpenGraphAction WithObjectType(FacebookOpenGraphObjects objectType)
    {
        this.ObjectType = objectType;
        return this;
    }

    public PublishFacebookOpenGraphAction WithUrl(Uri url)
    {
        this.Url = url;
        return this;
    }

    public PublishFacebookOpenGraphAction WithImage(Uri image)
    {
        this.Image = image;
        return this;
    }
}

Answer 1

I do not have a conversion from all members of PublishFacebookOpenGraphActionRequest to a fluent interface.
But maybe an half-automated generation of a fluent property-WithMember-pair is also a small step forward. This is possible with a ReSharper Live Template.

I have an example:

You can create the following code with that Live Template:

public FacebookOpenGraphActions Action { get; private set; }

public PublishFacebookOpenGraphAction WithAction(FacebookOpenGraphActions action)
{
    this.Action = action;
    return this;
}

by just typing fluentProp + ENTER and entering property name and its type.
