Specifies the local execution behavior of a service method.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|AutoDisposeParameters||Gets or sets whether parameters are to be automatically disposed.|
|Impersonation||Gets or sets a value that indicates the level of caller impersonation that the operation supports.|
|ReleaseInstanceMode||Gets or sets a value that indicates when in the course of an operation invocation to recycle the service object.|
|TransactionAutoComplete||Gets or sets a value that indicates whether to automatically complete the current transaction scope if no unhandled exceptions occur.|
|TransactionScopeRequired||Gets or sets a value that indicates whether the method requires a transaction scope for its execution.|
|TypeId||When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|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||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_Attribute::GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute::GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute::GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute::Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
|IOperationBehavior::AddBindingParameters||Implements the AddBindingParameters method.|
|IOperationBehavior::ApplyClientBehavior||Implements the client operation behavior.|
|IOperationBehavior::ApplyDispatchBehavior||Implements the service operation behavior.|
|IOperationBehavior::Validate||Implements the validation behavior.|
Use the attribute to indicate what operation-specific execution behavior the operation has when executed. (To specify execution behavior at the service level, use the ServiceBehaviorAttribute attribute.)
You can also use to configure a callback contract operation in a duplex client application. When used on a callback operation, the ReleaseInstanceMode property must be None or an InvalidOperationException exception is thrown at runtime.
The attribute is a programming model feature that enables common features that developers otherwise must implement themselves.
The AutoDisposeParameters property controls whether parameter objects passed to an operation are disposed when the operation completes.
The TransactionAutoComplete property specifies whether the transaction in which the method executes is automatically committed if no unhandled exceptions occur.
The TransactionScopeRequired property specifies whether a method must execute within a transaction.
The Impersonation property specifies whether the service operation can, must, or cannot impersonate the caller's identity.
The ReleaseInstanceMode property specifies when service objects are recycled during the method invocation process.
The following code example shows an operation that executes within a mandatory distributed transaction. The TransactionScopeRequired property indicates that the method executes under the caller's transaction and the TransactionAutoComplete property indicates that if no unhandled exceptions occur, the transaction commits automatically. If an unhandled exception does occur, the transaction is aborted.
