Provides developer-specified data for a pipeline segment.
Assembly: System.AddIn.Contract (in System.AddIn.Contract.dll)
Initializes a new instance of theclass.
This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
Returns the hash code for this instance.(Inherited from Attribute.)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
Returns a string that represents the current object.(Inherited from Object.)
|_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)|
Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
|_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)|
Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
|_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)|
Provides access to properties and methods exposed by an object.(Inherited from Attribute.)
You can use this attribute to assign data, in the form of name-value string pairs, for any purpose to a pipeline segment. For example, you can indicate that an add-in should be loaded into an external process.
Qualification data is only read by the host and is not consumed by the add-in system in any other way.
You can apply qualification data to a pipeline segment by placing a Pipeline Development.attribute next to the segment attribute. For more information about pipeline segments and their attributes, see
The following example applies qualification data to an add-in.
' This pipeline segment has ' two attributes: ' 1 - An AddInAttribute to identify ' this segment as an add-in. ' ' 2 - A QualificationDataAttribute to ' indicate that the add-in should ' be loaded into a new application domain. <AddIn("Calculator Add-in", Version:="188.8.131.52")> _ <QualificationData("Isolation", "NewAppDomain")> _ Public Class SampleV2AddIn
