Examples
The following example identifies 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="2.0.0.0")]
[QualificationData("Isolation", "NewAppDomain")]
public class SampleV2AddIn : Calculator2
{
' 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.

Public Class SampleV2AddIn
Remarks
The following methods, which maintain the store of information about available pipeline segments, use this attribute to identify an add-in.
This attribute is not required when an add-in is found exclusively by the FindAddIn method. The host has already identified the add-in by its type name and location, and therefore the attribute is not required for the add-in to be discovered.
This attribute should be used only on types that activate the segments of the pipeline. Types that represent objects passed between the host and the add-in do not need this attribute.

Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| Match(Object) |
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) |
Explicit Interface Implementations
| _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) |
| _Attribute.GetTypeInfoCount(UInt32) |
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) |
