AspNetCompatibilityRequirementsAttribute.RequirementsMode Property

Gets or sets the level of ASP.NET compatibility required by the service.

Namespace:  System.ServiceModel.Activation
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

'Declaration
Public Property RequirementsMode As AspNetCompatibilityRequirementsMode
	Get
	Set

Property Value

Type: System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode
The AspNetCompatibilityRequirementsMode that indicates the services required degree of ASP.NET compatibility. The default value is NotAllowed, so that users must explicitly design a service to be running in the compatibility mode.

ExceptionCondition
InvalidEnumArgumentException

The value is not a valid one for the AspNetCompatibilityRequirementsModeenum.

Use the RequirementsMode property to set the hosting mode in code. This can also be done by setting an application-level configuration flag aspNetCompatibilityEnabled. For more information, seeserviceHostingEnvironment.

At runtime, applications can detect whether ASP.NET compatibility mode is enabled by checking the value of the static property AspNetCompatibilityEnabled.
