PipelineStoreLocation Enumeration

Specifies alternative locations for a pipeline store instead of a path to a directory.

Namespace:  System.AddIn.Hosting
Assembly:  System.AddIn (in System.AddIn.dll)

[SerializableAttribute]
public enum PipelineStoreLocation

Member nameDescription
ApplicationBaseThe location specified by the AppDomainSetup.ApplicationBase property for setting up the application domain's host.

This enumeration currently contains only the ApplicationBase value.

The methods in the AddInStore class that use this enumeration enable partially trusted hosts, which may not have permission to discover their own location, to find and activate add-ins in their own directory.

You can use the AddInStore.Update(PipelineStoreLocation) and AddInStore.Rebuild(PipelineStoreLocation) method overloads to specify a location for updating or rebuilding the pipeline store, and the AddInStore.FindAddIns(Type, PipelineStoreLocation, String[]) method overload to specify a location for finding add-ins.

The following example uses the ApplicationBase value to activate an add-in from the pipeline store files, which are located in the host application's directory.

// Search for add-ins of type Calculator (the host view of the add-in) 
// specifying the host's application base, instead of a path, 
// for the FindAddIns method.

Collection<AddInToken> tokens = 
            AddInStore.FindAddIns(typeof(Calculator),PipelineStoreLocation.ApplicationBase);
