將Firebird Net提供程序集成到應用程序中

Question

在我的項目中，我使用Entity Framework 6通過嵌入式服務器類型連接到Firebird。 在安裝了Firebird Net Provider的計算機上，我的應用程序運行正常，但在沒有安裝Firebird Net Provider的計算機上，應用程序崩潰並出現錯誤：

具有不變名稱“ FirebirdSql.Data.FirebirdClient”的ADO.NET提供程序未在計算機或應用程序配置文件中注冊

如何在配置文件中注冊ADO.NET提供程序以避免此錯誤？ 這是我的app.config：

  <?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" />

        <providers>
          <provider invariantName="FirebirdSql.Data.FirebirdClient" type="FirebirdSql.Data.EntityFramework6.FbProviderServices, EntityFramework.Firebird" />
        </providers>
      </entityFramework>

        </assemblyBinding>
      </runtime>
    </configuration>

將此添加到您的[app|web|machine].config ：

<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>
</system.data>
