    I have recently updated a webpart which worked in SP2010 to SP2013, the upgrade process was changing the target framework and referencing the telerik.ui for 4.5

    After deploying the webpart into SP2013, i'm now getting this error:

    "that assembly does not allow partially trusted callers"

    I assume its to do with the changes in 4.5 security? has anyone experienced the same issue?

    I'd like to avoid putting the telerik.dll's in the GAC
