XmlWriter.WriteStartElement isn't virtual

[hawkerm]

Description

The single and 2 parameter versions of WriteStartElement in the docs state:

When overridden in a derived class, writes out a start tag with the specified local name.

However, they aren't marked virtual like the 3 parameter version.

Seems like this is an oversight and they should be overridable as well?

Reproduction Steps

public class MyXmlWriter : XmlWriter
{
    public override void WriteStartElement(string localName) // Error
    {
    }
}

Expected behavior

Able to override method.

Actual behavior

CS0506 error.

Regression?

No response

Known Workarounds

🤷‍♂️

Configuration

No response

Other information

These overloads just call the three parameter version with null for the missing values. You are only supposed to override the 3-parameter WriteStartElement method.

Thanks @filipnavara! It wasn't clear that was the case from the docs. Would be good to have a remark somewhere then in the xmldoc for the methods as such.
