Transform a Vector by a Quaternion

Question

In Microsofts Systems.Numerics (see exemplified: https://docs.microsoft.com/en-us/previous-versions/windows/xna/bb199541(v=xnagamestudio.41)) following function exists:

Vector3.Transform(Vector3 v, Quaternion q) to transform a specified Vector3 v around the specified Quaternion rotation q.

Is this function equivalent to Unitys:

v = q * v

calculation? If not, which function is the equivalent?

Well, i never used the XNA framework but yes, i'm pretty sure it's the same. If that's all you wanted to ask i guess you question is answers. However keep in mind that Unity uses a left handed coordinate system while XNA seems to be using a right handed system (just in case you want to translate some code)
