The CustomAssemblyLoading event handler receives an argument of the DashboardCustomAssemblyLoadingEventArgs type. The following properties provide information specific to this event.

Property Description
AllowLoading Gets or sets whether loading a custom assembly is allowed.
AssemblyPath Gets the path to the external assembly containing the Entity Framework model.
ContextName Gets the name of the Entity Framework context.
