	184 objects (plus 21 "4k" versions **)	163 objects (plus 10 "4k" versions **)
	347 total objects (plus 31 total "4k" versions **)

** "4k" versions: Quite a few of the String and RegEx functions that have NVARCHAR(MAX) input parameters, and/or output parameters, and/or return types have a second T-SQL wrapper object, pointing to the same .NET method, but that does not use any MAX type, instead using NVARCHAR(4000). The problem with NVARCHAR(MAX) is that if there is even one of them in the object's signature, then there is a noticable performance hit. If the function you are using has a "4k" version and the parameters, return type, or result set fields are guaranteed to never hold more than 4000 characters (or more accurately: 8000 bytes worth of characters since Supplementary Characters are 4 bytes each), then use the "4k" version as it will perform better.

What can SQL# do?

SQL# gives you the easiest access to the power of the CLR!
-- Over 340 Procs and Functions, 11 User-Defined Aggregates, 3 User-Defined Types, and more being added!
SQL# installs easily and in moments!
-- download one small install sql script, execute it, and enjoy the power of the CLR!
SQL# is backed up and restored with the database along with all other objects and data!
-- no need to worry about separate DLLs as with COM Extended Stored Procedures
SQL# has the PDF manual embedded in it!
-- if you ever lose the documention and aren't connected to the Internet, the worst off you are is one procedure call away from extracting the manual to disk!
SQL# saves countless hours learning CLR and .NET, not to mention the time spent testing and fixing (repreat several times)!
-- time is money and you have work to do so why stop and learn yet another language, especially when you might need to purchase additional software just to compile a basic function!
SQL# lets you focus on SQL programming without sacrificing the power of the CLR!
-- again, there is only so much time in the day so do you want to spend it NOT being productive?
