首先创建ADO.NET实体数据模型-生成DB Firebird .NET提供程序

Question

I have a problem with creating a Firebird DB from Entity Data Model (Model first, Database first all same mistake).

Setup:

• MS Visual Studio 2013 Pro
• Entity Framework 6.0.2
• FirebirdClient 4.1.0.0
• .NET4.5

I've created a Data connection to empty Firebird DB (all works fine). I created a blank ADO.NET Entity Data Model, created the model (3 tables with associations) and I want to create the Firebird DB from the model and it throws provider unsupported:

Your project references the latest version of Entity Framework; however, an EF database provider compatible with version could not be found for your data connection...

But I think, I use the correct one.

App.config code:

<system.data>
<DbProviderFactories>
  <add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient"/>
</DbProviderFactories>

<providers>
  <provider invariantName="FirebirdSql.Data.FirebirdClient" type="FirebirdSql.Data.FirebirdClient.FbProviderServices, FirebirdSql.Data.FirebirdClient"/>
  <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>

Any idea what's wrong?

Did you install the EF6 provider form Nuget:

install-package FirebirdSql.Data.FirebirdClient-EF6
