Nullability of reference types in type of parameter 'f1' of 'bool FileCompare.Equals(FileInfo f1, FileInfo f2)' doesn't match implicitly implemented member 'bool IEqualityComparer<FileInfo>.Equals(FileInfo? x, FileInfo? y)' (possibly because of nullability attributes).

The variable 'ex' is declared but never used

'MD5CryptoServiceProvider' is obsolete: 'Derived cryptographic types are obsolete. Use the Create method on the base type instead.' (https://aka.ms/dotnet-warnings/SYSLIB0021)
