I recommend you to take a look at our Entity Framework Query Samples.
They describe how to use several storage models with one conceptual model.
Take a look at this blog article as well.
Hope these links describe the scenario you are interested in.

We have already considered the situation with Enumeration support in Entity Framework here in our blog.
There was an Enumeration support added in the Entity Framework 4.2 June 2011 CTP, but it supports only Enums of integer type, while in PostgreSQL Enums are of literal type.
Could you please specify what Enum type are you interested in?

We have added the design time support for the Tinyint(1) as Boolean only in Devart Entity models (.edml) at the moment.
I recommend you to use Devart Entity models in your project instead of Microsoft Entity model. We have more control over the metadata in our models, and a more convenient designer - Entity Developer.

We don't provide this functionality at the moment.
If you are interested in it, you can add a suggestion on our Entity Developer User Voice.

There is a peculiarity in the handling of escape symbols in PostgreSQL, it differs from the SQL Standard a bit. First, you can turn on the standard_conforming_strings option on your server, in this case the
query will work correctly.
Please note, that this PostgreSQL behaviour will probably be changed for SQL Standard compatibility.
However, this setting will not change the Like behaviour. It is associated with the fact that EF provider works in the disconnected mode, and it doesn't have an opportunity to know server settings before the generated query is executed.
So, we recommend you to use the parameters instead of the literals in your query, like in the following example:
Code: Select all
var filteredSites = sites.Where(o => o.Host == "\").ToList();

I recommend you to create a new C# or Visual Basic class library, add a new or existing Devart Entity model or Devart LinqConnect model, and then simply reference this assembly in your projects.
If you are interested in implementing some business logic over the generated code, I recommend you to take a look at this article, for example. It deals with Entity Framework, if you are interested in LinqConnect, take a look at this LINQ to SQL article, our LinqConnect is LINQ to SQL-compatible.
