websocket-sharp\Net\CookieException.cs(10,10): Error CS0540: 'WebSocketSharp.Net.CookieException.ISerializable.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)': containing type does not implement interface 'System.Runtime.Serialization.ISerializable' (CS0540) (websocket-sharp)

Build error in r3427. Occurs when building for Release in VS2017 and MonoDevelop.

Inheritance from ISerializable seems to have been removed in r3410 (r3409 builds properly).

Commit log does not reveal what the intent was but I suspect the implemented functions should have been removed.

Removing the explicitly implemented functions allows the build to complete successfully in r3427 (but I am not sure if this is the correct fix).

___________________________________________________________________

Start with websocket-sharp/Net/CookieException.cs and compare revisions r3409, r3410, and r3427, focusing on the ISerializable declaration and explicitly implemented methods. Reproduce the Release build in VS2017 or MonoDevelop, then verify that the chosen correction removes CS0540 without breaking exception serialization.
