)

Parameters

hostViewOfAddIn
Type: System.Type

The type that defines the host's view of the add-in.

location
Type: System.AddIn.Hosting.PipelineStoreLocation

One of the enumeration values.

Currently the only value in this enumeration is the directory specified by the AppDomainSetup.ApplicationBase property that was used to set up the host's application domain.

addInFolderPaths
Type: System.String[]

(Optional). The path of the directory that contains one or more subdirectories of add-ins. Because this parameter takes an array of strings, you can specify more than one path.

This parameter is not required if your add-ins are located in the pipeline directory structure under the AddIns folder.

Return Value

Type: System.Collections.ObjectModel.Collection<AddInToken>
A collection of tokens that represent the add-ins that were found.

ExceptionCondition
InvalidPipelineStoreException

There is an access violation to the pipeline directory structure.

ArgumentException

location is an invalid PipelineStoreLocation value.

Use this method overload to enable a partially trusted host, which may not have path discovery permission to discover its own location, to find add-ins in its own directory.
