    Event Viewer: ReflectionTypeLoadException

    Hi Darren, just installed Event Viewer on a client's Umbraco install and got the following exception:

    Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

    Install details:

    • Umbraco v4.5.1 - upgraded from v4.0.4.2 (if that matters?)
    • ASP.NET 3.5
    • Windows Server 2003 - IIS 6

    Need any other details?

    Cheers, Lee.

    Hi Lee,

    I've not tested this with 4.5.1 I'm afraid.

    I'm also afraid to say it isn't going to get looked at quickly.... Unless you want to get stuck into the source?

    Doh, no worries!

    Sure I can take a look at the source. :-)   (Email me the SVN details.)

    It probably just needs to be recompiled against the v4.5 assemblies.

    Cheers, Lee.

    Quick follow up on this.  The problem isn't with the package/dashboard-control specifically, but with one of the Types in the assembly.

    From debugging the source, I found that it was trying to load "umbraco.interfaces.IFormHandler" ... which is really really weird, since that doesn't exist in the "interfaces.dll".

    The Umbraco instance is actually an upgrade to v4.5.1 - from v4.0.4.2 (which in turn had gone through an upgrade path from v3.0.3) - not sure if there is something lingering around elsewhere, but its very strange!

    Aside from that the Event Viewer works fine on my other Umbraco set-ups.

    Cheers, Lee.
