Block usage details: http://world.episerver.com/forum/developer-forum/Developer-to-developer/Thread-Container/2016/8/how-can-i-get-all-blocks-and-it39s-usages/

In addition, to list all block types, use IContentTypeRepository:

var contentTypeRepo = ServiceLocator.Current.GetInstance<IContentTypeRepository>();

IEnumerable<ContentType> allBlockTypes = contentTypeRepo.List().Where(x => typeof (BlockData).IsAssignableFrom(x.ModelType));

Hi and thanks for the reply

However the links provided just refers to other links and refers to some interface, no example of how to implement the interfaces are shown anywhere. 

There already is a default implementation of the interfaces referred to and you can just inject them in your code (typically in the constructor of a Controller or other class) or by using ServiceLocator.

Example of dependency injection:

public class MyController : Controller
{
    private readonly IContentRepository _contentRepo;
    private readonly IContentModelUsage _modelUsage;

    public MyController(IContentRepository contentRepo, IContentModelUsage modelUsage)
    {
        _contentRepo = contentRepo;
        _modelUsage = modelUsage;
    }
}

Example of ServiceLocator in static class:

public static class SomeHelper
{
    public static void DoStuff()
    {
        var contentRepo = ServiceLocator.Current.GetInstance<IContentRepository>();

        var modelUsage = ServiceLocator.Current.GetInstance<IContentModelUsage>();
    }
}

Hi,

Is there an equivilent to this for Episerver 6 R2?

Thanks
