First try after upgrading from 2.6. Using Postgres. Not sure what I might be missing. Tried to poke around for npgsql.dll and in the .config. Couldn't find the former and the latter seemed fine

Exception information.

LLBLGen Pro version: v3.5. Build: January 17th, 2013

Exception details:

Message: Failed to find or load the registered .Net Framework Data Provider. Source: System.Data Stack trace: at System.Data.Common.DbProviderFactories.GetFactory(DataRow providerRow) at System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName) at SD.LLBLGen.Pro.DBDriverCore.DBDriverBase.GetDbProviderFactory() at SD.LLBLGen.Pro.DBDriverCore.DBDriverBase.CreateConnection() at SD.LLBLGen.Pro.Gui.Controls.WizardPages.MetaDataRetrievalWizard_Step_ConnectionData.TestConnectionData(Boolean showSuccess)

Inner exception: <null>

You should add the DBProviderFactory manually on you .config file. Please read this...

I copied that Factory from LLBLGenPro.exe.config to my .configs to make them work, so I'd hope it was correct to start with. Perhaps you missed the subject line?

Now I'm wondering where npgsql.dll v 2.0.4.0 even is.

Just get the latest npgsql.dll from the postgresql foundry website. http://npgsql.projects.pgfoundry.org/

If you're installing the .net 4.0 version, be sure to run the v3 designer on .net 4 as well with the .net 4 runner (available in windows menu)

Thanks, that worked.

So, am I the first person to use postgres on 3.x, did I miss something in the documentation, or do other people install npgsql somewhere on their system?

I just put it in my path of my software I write.

No, you are not the first one (i.e: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=19590)

Mostly the reason is the way .net tries to found the db provider factory and the version you have registered on your machine.

Indeed, it's not uncommon, it's just a bit cumbersome to get started with npgsql.
