Examples

var student = GetStudent();
var cachedType = ReflectionCache.GetCachedType<Student>();

var grade = cachedType
    .Properties[nameof(Student.Grade)]
    .GetValue<Student, double>(student);

grade *= 1.5;
cachedType
    .Properties[nameof(Student.Grade)]
    .SetValue<Student, double>(student, grade);

var studentDisplayName = cachedType
    .Attributes
    .OfType<DisplayAttribute>()?.Name;
