I decided to put the example in the remarks of the type, because I think it's the most visible place.
| static string myTransform(ref FileSystemEntry entry) => | ||
| entry.ToFullPath(); | ||
|
|
||
| static bool myPredicate(ref FileSystemEntry entry) => | ||
| !entry.IsDirectory && | ||
| Path.GetExtension(entry.ToFullPath()).Equals(".txt", StringComparison.InvariantCultureIgnoreCase); |

I tried to write the same example in Visual Basic but the predicate and the transform were giving me headaches. I know there are no local methods in VB, but I couldn't figure out the syntax for the delegate with a ByRef argument. I'll give it another try soon.
Also, I was getting a build failure when trying to use ByRef FileSystemEntry:
FileSystemEntry' is obsolete: 'Types with embedded references are not supported in this version of your compiler.
I'll ask someone in my team why this is happening.

I noticed this class has no examples, so I added one with basic filtering options. Whenever I get a chance, I'll write additional examples with more advanced filters.
