The behavior of 'StringBuilder.Append(ref StringBuilder.AppendInterpolatedStringHandler)' could vary based on the current user's locale settings. Replace this call in 'SampleFeed.WithItems(string, params string[])' with a call to 'StringBuilder.Append(IFormatProvider, ref StringBuilder.AppendInterpolatedStringHandler)'.
