Начиная с платформа .NET Framework 4, свойство объекта, HashAlgorithm возвращаемого методом Assembly.GetReferencedAssemblies , имеет значение AssemblyHashAlgorithm.None , если нет хэш-алгоритма для сборки, на которую указывает ссылка, или если хэш-алгоритм сборки, на которую указывает ссылка, не идентифицируется System.Configuration.Assemblies.AssemblyHashAlgorithm перечислением .AssemblyName В предыдущих версиях платформа .NET Framework HashAlgorithm свойство возвращалось AssemblyHashAlgorithm.SHA1 в этой ситуации.
