    "System.MissingMethodException" when using Html.ConvertImgToSrcSet

    This is on Umbraco 8.6

    On my DocType ContentPage, I have a RichText property editor with alias RichTextTest. When I do this in a view:

    @Html.ConvertImgToSrcSet(Model, ContentPage.GetModelPropertyType(m => m.RichTextTest).Alias)
    

    then I get a System.MissingMethodException. I get the exception whether there are images in the RTE or not.

    I can use Slimsy's other methods like GetCropUrl and GetSrcSetUrls without trouble.

    My Image media type has the Upload property set to Image Cropper.

    Any idea what I am doing wrong?

    Here is the complete error trace:

    [MissingMethodException: Method not found: 'Void Umbraco.Web.PropertyEditors.ValueConverters.RteMacroRenderingValueConverter..ctor(Umbraco.Web.IUmbracoContextAccessor, Umbraco.Web.Macros.IMacroRenderer)'.]

    Thank you David, I raised an issue with Slimsy on GitHub.

    However, it could also be related to me doing something wrong which would cause the code to try and call the wrong constructor. The strange thing is, I vaguely remember using ConvertImgToSrcSet in a somewhat similar scenario and it worked back then.

    This was indeed a bug, caused by a changed method in Umbraco 8.6.

    The latest Slimsy version v3.0.0-beta4 fixes the issue. This version requires Umbraco 8.6+. Thank you to Jeavon for the quick fix!

    @neel: I didn't have to change anything on my end. After updating to Slimsy version v3.0.0-beta4, it worked as described in the Slimsy documentation.

    If you post your code which doesn't work, may be I have an idea. It's hard to say something without that.
