Ensure that 'CdpAppBase.Dispose' is declared as public and sealed (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)

A call to Dispose(true) should clean up both managed and native resources. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)
