Remarks

Use can use the constants from the UASecurityPolicyUriStrings class as values for this property.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

Alternatively, you can override the endpoint selection policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.EndpointSelectionPolicy.
