Visual Basic contains several keywords that are contextual keywords. For example, From is a keyword in a Linq expression, but not elsewhere, and you can still have variables named From without enclosing them in [].

Because of the limitations of regular expressions, the VisualBasicFormattingInfo cannot determine when a contextual keyword should be treated as a keyword and when it should be treated as a regular identifier. Because of this, it always treats them as keywords.

You can prefix an identifier that is also a contextual keyword with ` (e.g. `From) to prevent it from being highlighted as a keyword. The ` character will not appear in the formatted output, and the identifier will not be highlighted.

You can specify identifiers that should be colored as type names using the Types property. These identifiers will then always be formatted as type names (even in contexts where they are not). Like with contextual keywords, you can prefix an identifier with ` to prevent it from being highlighted as a type name.

XML literals are supported, however the XML literals must be marked explicitly with with [xml][/xml]. For example, this would look like this with a simple XML literal: Dim xmlLiteral = [xml]<Foo />[/xml].

The [xml][/xml] tags will not be included in the output, and the contents of those tags will be formatted as XML literals. Embedded expressions in XML literals (which are delimited by <%= %> blocks) are also supported, and the contents of embedded expressions will be formatted as Visual Basic code. However, due to the limitations of regular expressions, having an XML literal inside an embedded expression in another XML literal is not supported.
