Remarks

Use can use the constants from the OpcLabs.EasyOpc.UA.Engine.UASecurityPolicyUriStrings class as values for this property.

Example values:

"http://opcfoundation.org/UA/SecurityPolicy#Basic128Rsa15",

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 OpcLabs.EasyOpc.UA.Engine.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 OpcLabs.EasyOpc.UA.Engine.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.
