Configuring the .NET Connector

Please see the following environment-specific sections for information about configuring the .NET Connector:

Referencing the Library Files

To reference library files with Microsoft Visual Studio:

  1. Select the project in the Solution Explorer.
  2. Select Add Reference from the Project menu.
  3. When the Add Reference dialog box opens, browse to select the appropriate library files.

Optionally, the library files can be copied to the specified location.

Before you can use an EDB .NET class, you must import the namespace into your program. Importing a namespace makes the compiler aware of the classes available within the namespace. The namespace is:

EnterpriseDB.EDBClient

If you are using Entity Framework 6, the following additional namespace is required:

EntityFramework6.EntepriseDB.EDBClient

The method you use to include the namespace varies by the type of application you are writing. For example, the following command imports a namespace into an ASP.NET page:

<% import namespace="EnterpriseDB.EDBClient" %>

To import a namespace into a C# application, write:

using EnterpriseDB.EDBClient;

Add the <DbProviderFactories> entries for the ADO.NET driver for Postgres to the app.config file. Add the following entries:

<add name="EnterpriseDB.EDBClient"
  invariant="EnterpriseDB.EDBClient"
  description=".NET Data Provider for EnterpriseDB PostgreSQL”
  type="EnterpriseDB.EDBClient.EDBFactory, EnterpriseDB.EDBClient, Version=4.1.6.1, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7"
  support="FF"/>

In the project’s app.config file add the following entry for provider services under the EntityFramework/providers tag:

<provider invariantName="EnterpriseDB.EDBClient"
  type="EnterpriseDB.EDBClient.EDBServices, EntityFramework6.EnterpriseDB.EDBClient">
</provider>

The following is an example of the app.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
  </configSections>

    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>

 <entityFramework>
   <providers>
     <provider invariantName="EnterpriseDB.EDBClient" type="EnterpriseDB.EDBClient.EDBServices, EntityFramework6.EnterpriseDB.EDBClient"></provider>
   </providers>
 </entityFramework>

 <system.data>
   <DbProviderFactories>
     <remove invariant="EnterpriseDB.EDBClient"/>
     <add name="EnterpriseDB Data Provider" invariant="EnterpriseDB.EDBClient" support="FF" description=".Net Framework Data Provider for Postgresql" type="EnterpriseDB.EDBClient.EDBFactory, EnterpriseDB.EDBClient"/>
   </DbProviderFactories>
 </system.data>

</configuration>
Note

The same entries for <providers> and <DbProviderFactories> are valid for the web.config file and the app.config file.

Depending upon the type of application you are using, you may be required to import the namespace into the source code (see Referencing the Library Files).

For usage information about Entity Framework, refer to the Microsoft documentation.

EDB VSIX for Visual Studio 2015/2017/2019

The EDB Data Designer Extensibility Provider (EDB VSIX) is a component that integrates Advanced Server database access into Visual Studio, thus providing Visual Studio integrated features.

EDB VSIX allows you to connect to Advanced Server from within Visual Studio's Server Explorer and create a model from an existing database. Therefore, if Visual Studio features are desired, then EDB VSIX must be utilized.

EDB VSIX files are located in the following directory:

C:\Program Files\edb\dotnet\vsix

The files available at the above location are:

edb_logo.ico EnterpriseDB.vsix SSDLToPgSQL.tt System.ValueTuple.dll

Installation and Configuration for Visual Studio 2015/2017/2019

Use the following steps to install and configure EDB VSIX.

Step 1: Install EDB VSIX to the desired version of Visual Studio with the EnterpriseDB.vsix installer.

If you already have an earlier version of the VSIX installed, we highly recommended that you uninstall it to avoid conflicts.

It is no longer necessary or recommended to have EnterpriseDB.EDBClient in your global assembly cache (GAC).

Step 2: Relaunch Visual Studio and verify from the Tools > Extensions and Updates… menu that the EDB extension is installed.

Step 3: Use the gacutil utility at the Visual Studio Developers Command Line to add following libraries to the global assembly cache (GAC):

System.ValueTuple.dll System.Threading.Tasks.Extensions.dll System.Runtime.CompilerServices.Unsafe.dll System.Memory.dll Microsoft.Bcl.AsyncInterfaces.dll System.Text.Json.dll

For example:

> gacutil.exe /i System.ValueTuple.dll

Step 4: From the Server Explorer, right-click on Data Connections, click Add Connection, and verify that the Enterprisedb Postgres Database data source is available.

Model First and Database First Usage

Step 1: Add the <DbProviderFactories> entries for the ADO.NET driver to the machine.config file. Include the following entries:

<add name="EnterpriseDB.EDBClient"
  invariant="EnterpriseDB.EDBClient"
  description=".NET Data Provider for EnterpriseDB PostgreSQL"
  type="EnterpriseDB.EDBClient.EDBFactory, EnterpriseDB.EDBClient, Version=4.1.6.1, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7"
  support="FF"/>

For the attribute-value pairs, the double-quoted strings should not contain excess white space characters, but be configured on a single line. The examples shown in this section may be split on multiple lines for clarity, but should actually be configured within a single line such as the following:

description=".NET Data Provider for EnterpriseDB PostgreSQL"

For 64-bit Windows, the machine.config file is in the following location:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config

For 32-bit Windows, the machine.config file is in the following location:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config

Step 2: Place the DDL generation template SSDLToPgSQL.tt in the Visual Studio EntityFramework Tools\DBGen\ folder as shown in the following example:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\EntityFramework Tools\DBGen\
Note

Select this template SSDLToPgSQL.tt in your EDMX file properties.

Step 3: Add the EnterpriseDB.EDBClient.dll and EntityFramework6.EnterpriseDB.EDBClient.dll files to project references. see Referencing the Library Files for information about referencing library files.

Step 4: Configure your Entity Framework application in either of following two ways:

  • Code-based
  • Config-based.

Code-based

Define a class that inherits from DbConfiguration in the same assembly as your class inheriting DbContext. Ensure that you configure provider services, a provider factory, and a default connection factory as shown below:

using EnterpriseDB.EDBClient;
using System.Data.Entity;

class EDBConfiguration : DbConfiguration
{
  public EDBConfiguration()
  {

      var name = "EnterpriseDB.EDBClient";

      SetProviderFactory(providerInvariantName: name,
      providerFactory: EnterpriseDB.EDBClient.EDBFactory.Instance);

      SetProviderServices(providerInvariantName: name,
      provider: EnterpriseDB.EDBClient.EDBServices.Instance);

      SetDefaultConnectionFactory(connectionFactory: new EnterpriseDB.EDBClient.EDBConnectionFactory());
  }
}

Config-based

In the project’s app.config file, add the following entry for provider services under the EntityFramework/providers tag:

<provider invariantName="EnterpriseDB.EDBClient"
  type="EnterpriseDB.EDBClient.EDBServices, EntityFramework6.EnterpriseDB.EDBClient">
</provider>

The following is an example of the app.config file.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
  </configSections>

    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>

  <entityFramework>
    <providers>
      <provider invariantName="EnterpriseDB.EDBClient" type="EnterpriseDB.EDBClient.EDBServices, EntityFramework6.EnterpriseDB.EDBClient"></provider>
    </providers>
  </entityFramework>

  <system.data>
    <DbProviderFactories>
      <remove invariant="EnterpriseDB.EDBClient"/>
      <add name="EnterpriseDB Data Provider" invariant="EnterpriseDB.EDBClient" support="FF" description=".Net Framework Data Provider for EDB Postgres" type="EnterpriseDB.EDBClient.EDBFactory, EnterpriseDB.EDBClient"/>
    </DbProviderFactories>
  </system.data>

</configuration>
