Hi Thomas,
 
You will need to set the DefaultConnectionFactory. We talk about this topic in the DevForce Resource Center.
 
Be sure to also write an implementation of IDbConnectionFactory. (as shown in the link above)

Connection string for model first:

connectionString="metadata=res://*/model.EBModel.csdl|res://*/model.EBModel.ssdl|res://*/model.EBModel.msl;provider=Devart.Data.PostgreSql;provider connection string="User Id=postgres;Host=localhost;Database=postgres;Persist Security Info=True;Schema='""ETERADEV""'"" providerName="System.Data.EntityClient"

And when I get the error I am using CodeFirst (ModelFirst is working).

I get the error when I compile the solution with an included .CF file (as I said, you can try it if you modify the demo WPF CodeFirst to use the devart provider instead of SqlServer)

Hi Thomas,
 
I'm confused. Are you using ModelFirst or CodeFirst?
 
When you create an edmx based on an existing PostgreSql DB, what does the connectionSting look like?

I tried to use your model first WPF tutorial application and when i changed the connection string to 

<add name="CodeFirstWalk" connectionString="User Id=postgres;Host=localhost;Database=postgres;Persist Security Info=True;Schema='&quot;ETERADEV&quot;'" providerName="Devart.Data.PostgreSql" />

I got 

An error occurred during metadata generation and a metadata file could not be created.  Error: Keyword not supported: 'host'. G:\Program Files (x86)\MSBuild\IdeaBlade\IdeaBlade.DevForce.Common.targets 110 5


If you want to try it out just install the Devart PostgreSql provider and change the string.
