The description of the phxsoftware SQlite connectivity layer has this:
User-Defined Functions & Collating Sequences
Full support for user-defined functions and collating sequences means that in many cases if SQLite doesn't have a feature, you can write it yourself in your favorite .NET language. Writing UDF's and collating sequences has never been easier.
Could someone give a bare-bones example of the steps involved in writing UDFs for SQLite "in your favorite .NET language", or provide a link where this is described in detail?
Thanks
