Applied to a service to indicate whether that service can be run in ASP.NET compatibility code.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|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.)|
|IServiceBehavior::AddBindingParameters||Adds custom data that the binding elements can access to support the implementation of the contract.|
|IServiceBehavior::ApplyDispatchBehavior||Checks that the type of hosting is consistent with the ASP.NET compatibility requirements.|
|IServiceBehavior::Validate||Validates the service behavior.|
When applied to a service implementation class, this attribute indicates whether this service requires or supports ASP.NET compatibility mode to be enabled for the hosting application domain (AppDomain).
AppDomains hosting services can run in two different hosting modes:
Mixed Transports Mode (Default): In this mode, services do not participate in the ASP.NET HTTP pipeline. This guarantees that a service behaves consistently, independent of hosting environment and transport.
ASP.NET Compatibility Mode: In this mode, services participate in the ASP.NET HTTP pipeline in a manner similar to ASMX services. ASP.NET features such as File Authorization, UrlAuthorization, and HTTP Session State are applicable to services running in this mode.
The hosting mode is controlled by the application-level configuration flag aspNetCompatibilityEnabled.
This flag is false by default and thus services run in the Mixed Transports Mode unless you explicitly opt into the ASP.NET compatibility mode.
For more information aboutASP.NET compatibility mode, see serviceHostingEnvironment.
Users must explicitly opt-in for the ASP.NET compatibility mode when implementing the service by setting the RequirementsMode property on the in the following examples.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
