title: ADO.NET Data provider for Firebird in Visual Studio 2015
body: <p>I am struggling creating a Firebird connection in Visual Studio 2015. I have a C# class library with which I would like to connect to a Firebird database.
  I installed these plugins from NuGet:</p>

  <p>But when I try to add a new Item "ADO.NET Entity Data Model" with "EF Designer from database", the Firebird connection is not listed:
  <a href="https://i.stack.imgur.com/0o6np.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0o6np.png" alt="enter image description here"></a></p>
  
  <p>Reading articles on the internet showed that an entry in machine.config should have been made. But this didn't happen. There is no Firebird entry in that config file.</p>
  
  <p>The "FirebirdSql.Data.FirebirdClient" reference exists in the Visual Studio project.</p>
  
  <p>The entry in the App.config file is:</p>
  
  <pre><code>&lt;DbProviderFactories&gt;
        &lt;remove invariant="FirebirdSql.Data.FirebirdClient" /&gt;
        &lt;add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient" /&gt;
  &lt;/DbProviderFactories&gt;
  </code></pre>
  
  <p>I as well installed the SQLite plugins just to see if this provider behaves the same. And indeed it wasn't listed either in the "Choose Data Source" dialog. I guess I make a general mistake.</p>
  
  <p>Can anybody help me with this issue? How can I create a database connection to my Firebird database?</p>
