Provide an overridable implementation of Dispose(bool) on 'MyUaClient' or mark the type as sealed. A call to Dispose(false) should only clean up native resources. A call to Dispose(true) should clean up both managed and native resources. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)
