Re: [gentle-devel] Onto the subject of switching providers "on the fly", I just can't make a nice wrapper around it....

I have not. However, I have set up a simple "sample" with a mix of my =20=

code and the ideas I've heard so far.

The .zip file containing all the solution (including a db sample and =20
a nice readme) is at: http://www.dracula.com.ar/=20
ChangeMyProviderOhYay.zip

The file is 850k in length and it includes all (gentle and log4net) =20
compiled. The Gentle version is the "latest" from source. (I may have =20=

changed the version number, but bear in mind, it's the latest).

Any Help will be appreciated, since I cannot find the "tricky" part =20
of gentle that keeps me from doing this.

Thanks in advance,

P.S.: please if you're going to use the sample, read the readme.txt =20
file which explains what to do, althought I tried to make this as =20
automatic as possible, you will need to execute a couple of Database =20
Scripts and modify the app.config.
