public:
 property System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode RequirementsMode { System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode get(); void set(System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode value); };
public System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode RequirementsMode { get; set; }
member this.RequirementsMode : System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode with get, set
Public Property RequirementsMode As AspNetCompatibilityRequirementsMode

Property Value

The AspNetCompatibilityRequirementsMode that indicates the services required degree of ASP.NET compatibility. The default value is Allowed.

Exceptions

The value is not a valid one for the AspNetCompatibilityRequirementsModeenum.

Remarks

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.
