    Could not load type 'Umbraco.Core.IApplicationEventHandler' Umbraco v4.11.10

    I have installed the latest version of UComponents on an Umbraco 4.11.10 installation, but when it is done installing I get the following error:

    Could not load type 'Umbraco.Core.IApplicationEventHandler' from assembly 'Umbraco.Core, Version=1.0.4926.14927, Culture=neutral, PublicKeyToken=null'.

    After checj=king around it seems that it should reference Umbraco.Web instead of Umbraco.Core in 4.11.10 and the our.umbraco page does state that uComponents 6 does 100% support 4.11, so what is going wring here?

    Hi Dave,

    Unfortunately the compatibility chart on the our.umbraco page doesn't take into account each package version against Umbraco version.

    We made our own compatibility matrix here:

    If you try uComponents v5.5.4, that should be fine.
