How to split a stacktrace line into namespace, class, method file and line number?

Question

C# stack traces take the following form:

   at Foo.Core.Test.FinalMethod(Doh doh) in C:\\Projects\\src\\Core.Tests\\Test.cs:line 21
   at Foo.Core.Test.Anoth

StackTraceParser can parse a stack trace text output (e.g. typically returned by Environment.StackTrace or Exception.StackTrace) back into a sequence of stack trace frames, including the following components:

Type
Method
Parameter types and names
File and line information, if present

It is available as a NuGet source package that directly embeds into a C# project.

However it requires a few functions to specify and it's usage is not immediately obvious.

public static IEnumerable Parse(
    string text,
    Func tokenSelector,
    Func methodSelector,
    Func parameterSelector,
    Func, TParameters> parametersSelector,
    Func sourceLocationSelector,
    Func selector)
