…nstration Retargets both projects from net7.0 to net10.0. Adds a mixed-type ArrayList to the sample with two read paths - a matching cast that returns the value and a wrong cast that compiles and throws InvalidCastException at run time - plus two tests covering them. Kept out of Program.cs so the sample still runs to completion.

ArrayListto the sample with two read paths: a matching cast that returns the value, and a wrong cast that compiles and throwsInvalidCastExceptionat run time. Two tests cover them. The new members live onCollection, not inProgram.cs, so the sample still runs to completion.Build clean (0 warnings, 0 errors), 5/5 tests pass on .NET 10.0.10.
