Hi,
I'm relatively at Visual Studio and their stuff...
Until some monhts ago, another developer care of this, but, at moment, I'm the responsible for this, and I have no one to help me with this...

I convert my application to postgres, but, I cant do it work...
Then, for sure, I create a new application, put the correct dependences, but, the same error occour

at time:
- vs2008 version 9.0.30279.1 SP
- .NET Framework version 3.5 SP1
- dotConnect for PostgreSQL 4.55.39 Standard

I follow theese steps:
- Create a new project (smart device) - It's a pocket application





- Then I click on 'Project' > 'Add Reference...'
- Clicked on 'Browse' tab, select my devart instalation folder and selected this DLLs: 'Devart.Data.dll' and 'Devart.Data.PostgreSql.dll'



- It's my code with error... What I'm doing wrong ? I already try a lot of things, read a lot of forums, but nothin solve my problem...



Note: If I click on the error, the vs don't fix it to me

Please, help-me.

Please make sure that you are using dotConnect for PostgreSQL Mobile Edition, not the desktop version.

I have bought this dotConnect:

on Key Features have this:

- .NET Compact Framework support


this is the correct, isn't ?

Yes, it is correct.
