Why “Equals” method resolution with generics differs from explicit calls

Question

I have the following example:

namespace ComparisonExample
{
    class Program
    {
        static void Main(string[] args)
        {
            var hello1          


        

Answer 1

Addition from MSDN:

Unbounded Type Parameters.
Type parameters that have no constraints, such as T in public class SampleClass { }, are called unbounded type parameters.
Unbounded type parameters have the following rules:

• The != and == operators cannot be used because there is no guarantee that the concrete type argument will support these operators.
• They can be converted to and from System.Object or explicitly converted to any interface type.
• You can compare to null. If an unbounded parameter is compared to null, the comparison will always return false if the type argument is a value type.

In this case TValue is converted to System.Object and Equals method called.
