Some additional ones I haven't seen mentioned so far:

* FluentValidation: excellent validation library, keeps validation rules grouped together and easy to keep track of - https://github.com/JeremySkinner/FluentValidation

* AutoFixture: great for the "Arrange" phase of unit tests. Populates object graphs with test data, highly customizable. There's a bit of a learning curve. Pairs nicely with xUnit but can be used with any TDD library - https://github.com/AutoFixture/AutoFixture

* Shouldly: a different approach to unit test assertions using "Should" that I find more readable. Also had friendlier error messages when assertions failed - https://github.com/shouldly/shouldly

Shameless plug of my own library:

* Regextra: aims to solve some common regex related scenarios. Features a Passphrase Regex Builder to generate a pattern for passphrase criteria, and also supports named templates and a few utility methods - https://github.com/amageed/Regextra

LINQ isn't SQL-specific and does apply generally. It can be used against the standard .NET framework objects and collections. There are different LINQ focuses or flavors, and there are 2 ways to write queries. There's LINQ to Objects, LINQ to XML, LINQ to SQL (no longer actively maintained; nowadays Entity Framework is the Microsoft alternative), and you can write your own LINQ providers to target other purposes.

As for syntax, there's the fluent syntax (chained methods), and there's the query syntax which is syntactic sugar that gets compiled to the methods. The query syntax is probably the biggest reason people mistake LINQ for being SQL specific since it resembles SQL.

E.g.,

  var results = SomeCollection.Where(c => c.SomeProperty < 10)
                              .Select(c => new { c.SomeProperty, c.OtherProperty });

The same thing in query syntax:

  var results = from c in SomeCollection
                where c.SomeProperty < 10
                select new { c.SomeProperty, c.OtherProperty };

Then you can iterate over both the same way:

  foreach (var result in results)
  {
      Console.WriteLine(result);
  }

If you're interested in something similar for .NET / C#, check out my Regextra library, specifically the Passphrase Regex Builder: https://github.com/amageed/Regextra

As the name suggests though, the focus was on passphrase criteria and it wasn't to produce a DSL for general regex building. The library also supports named templates and a few utility methods.
