C# how to overload operator + for universal class

public struct Vector3<T>
{
    private T X { get; set; }
    private T Y { get; set; }
    private T Z { get; set; }

    public Vector3(T x, T y, T z) : this()
    {
        this.X = x;
        this.Y = y;
        this.Z = z;
    }

    public static Vector3<T> operator +(Vector3<T> v1, Vector3<T> v2)
    {
        return new Vector3<int>(v1.X + v2.X, v1.Y + v2.Y, v1.Z + v2.Z);
    }
}

Gives error: Cannot apply operator '+' to oparands of type 'T' and 'T'.

Please help resolve.

You can overcome that limitation on your own risk, by changing templated private members of the class to dynamic type. Example: 

public struct Vector3<T>
{
    private dynamic X { get; set; }
    private dynamic Y { get; set; }
    private dynamic Z { get; set; }
    ...
    ....
}

There is no way, unfortunately, in C# to restrict template parameter to numeric values (I guess it is what you are trying to achieve).
