How to rewrite django auth in c#?

Question

C++ / C#

This is how django stores passwords:

pbkdf2_sha256$20000$jo0zZbQiNrBR$MTjatXJlTjTn6x248FwXipHV1MdoA/xuMXkUC1pg48M=

How does it form this line? That is, it is clear that .split('$')[0, 2] = algorithm, hash. What is 20000? Number of iterations? Does it always use sha256 by default? Or selects the algorithm randomly?
The main question is, how can I port the "check_password" method to C#? The above line contains the password "admin". How can I write a method that will turn "admin" into this string?
