One of the enumeration values that specifies the trust level.
The host view of the add-in.
This method overload loads the add-in into an automatically generated application domain. If you want to specify a name for the new application domain, use the Activate(Of T)(AddInSecurityLevel, String) overload.
This method sets the base directory for the application domain to be the location of the add-in assembly. It also looks for the configuration file [addinassemblyname].dll.config and, if found, sets it to be the configuration file for the new application domain.
The following example shows how to activate an add-in, identified by the chosen token, in an automatically generated application domain with a specified security level.
'Ask the user which add-in they would like to use. Dim selectedToken As AddInToken = ChooseAddIn(tokens) 'Activate the selected AddInToken in a new 'application domain with the Internet trust level. Dim CalcAddIn As Calculator = selectedToken.Activate(Of Calculator)(AddInSecurityLevel.Internet) 'Run the add-in using a custom method. RunCalculator(CalcAddIn)
