Unable to validate code scanning workflow: error: getWorkflow() failed: Error: Expected to find a code scanning workflow file at D:\a\durabletask-dotnet\durabletask-dotnet\.github\workflows\codeQL.yml, but no such file existed. This can happen if the currently running workflow checks out a branch that doesn't contain the corresponding workflow file.

Nullability in constraints for type parameter 'TState' of method 'TestLogger.BeginScope<TState>(TState)' doesn't match the constraints for type parameter 'TState' of interface method 'ILogger.BeginScope<TState>(TState)'. Consider using an explicit interface implementation instead.

Nullability of reference types in return type of 'IDisposable? TestLogger.BeginScope<TState>(TState state)' doesn't match implicitly implemented member 'IDisposable ILogger.BeginScope<TState>(TState state)' (possibly because of nullability attributes).

Nullability in constraints for type parameter 'TState' of method 'TestLogger<T>.BeginScope<TState>(TState)' doesn't match the constraints for type parameter 'TState' of interface method 'ILogger.BeginScope<TState>(TState)'. Consider using an explicit interface implementation instead.
