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

public AspNetCompatibilityRequirementsMode RequirementsMode { 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 Allowed.

ExceptionCondition
InvalidEnumArgumentException

The value is not a valid one for the AspNetCompatibilityRequirementsMode enum.

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, see <serviceHostingEnvironment>.

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