Pre-release Versions of System.Data.SQLite packages?
[On user-defined function addition]

The BindFunction() function in System.Data.SQLite relies on the same SQLite library feature as is used by the CLI .load meta-command, where the function set usable via SQL is extended, as is documented at [Application-Defined SQL Functions](https://sqlite.org/appfunc.html).

If you had read the [command-line shell doc](https://sqlite.org/cli.html), you would have found section 13 and avoided that particular puzzlement.

The documentation for SQLite is quite excellent. I suggest that, instead of using Google and sifting through much irrelevant stuff, you use the [Permutated Title Index](https://sqlite.org/sitemap.html#pindex).  You would learn a lot about the existence of capability just looking at those index entries.

FWIW, I second Ryan's sentiment that you would do better by studying the docs than by bringing every little question (already answered there) to this forum.
