Resolved Does documentation claim you can split Strings on Strings?

[2Flow2]

I don't understand what I am reading wrong...
According to this section of the documentation, Strings should be able to be split using a second String as the seperator. The documentation says:

Split(String, StringSplitOptions)​

Splits a string into substrings that are based on the provided string separator.

public string[] Split (string? separator, StringSplitOptions options = System.StringSplitOptions.None);

Parameters​

separator String
A string that delimits the substrings in this string.

options StringSplitOptions
A bitwise combination of the enumeration values that specifies whether to trim substrings and include empty substrings.

Returns
String[]
An array whose elements contain the substrings from this instance that are delimited by separator.

However, when I actually attempt this, the code fails and throws an error, claiming that the seperator must be a char or string array, but not a String itself.
Argument 1: Cannot conver from 'string' to 'char'.

In fact, this seems to be backed up by the code internals itself. If I look at System.String, I can find overloads for a variety of seperator arguments, but none of them are for a seperator simply of type String:

        public String[] Split(char[] separator, int count, StringSplitOptions options);

        public String[] Split(String[] separator, StringSplitOptions options);

        public String[] Split(String[] separator, int count, StringSplitOptions options);

        public String[] Split(char[] separator, int count);

        public String[] Split(params char[] separator);

        public String[] Split(char[] separator, StringSplitOptions options);

The documentation says that the overload accepting a String as a seperator has been present since .NET Core 2.0? So this shouldn't be a brand-new feature to .NET, I don't believe?

So what am I reading incorrectly in this documentation? What does the linked section mean if not that a String can be used as the seperator to .Split() other strings? I'm completely baffled.

That is the documentation for .Net 6 (look at Version top left), it has different parameters than .Net Framework.
In .Net Framework you have to use a string array if you want to split by a string, see String.Split Method (System)

Your reply sent me down a learning rabbit hole into what the differences between all of the .NET versions are ultimately ending here. I think I have a pretty good grasp of it now, and I'm using .NET Framework 4.6 for my current project, so your response makes perfect sense. Thank you so much for your reply!
