A library for extracting square roots of large numbers in C#?

Question

.NET

Good day to all. The question actually is whether there is a c# library for extracting square roots from very large numbers. BigInteger and IntX are not suitable, because the square root functions in these libraries return the result rounded to the nearest integer. I would be very grateful for help.

If you only need to check whether the number is a perfect square, you can use your libraries to square the found rounded root and compare with the original number.
