.NET: How to efficiently check for uniqueness in a List of 50,000 items?

Question

In some library code, I have a List that can contain 50,000 items or more.

Callers of the library can invoke methods that result in strings being added to the list. Ho

Possibly off-topic, but if you want to scale very large unique sets of strings (millions+) in a language-independent way, you might check out Bloom Filters.
