The degree of a foliation $\mathcal{F}$ on the complex projective plane $\mathbb{C}\mathbb{P}^2$

Question

Let $\mathcal{F}$ be a Singular Holomorphic Foliation on the Complex Projective Plane $\mathbb{C}\mathbb{P}^2$.

It is well-known that there are too many different equivalent ways to define the Degree of the foliation $\mathcal{F}$.

The question is:

What is the most elegant and creative way to define the degree of the foliation $\mathcal{F}$ on the complex projective plane $\mathbb{C}\mathbb{P}^2$?
