DDEX 提供程序 3.0.1 for Firebird with Visual Studio Pro 2013

Question

我已经安装了 FirebirdSql.Data.FirebirdClient v4.6.4.0（来自 msi）然后是 DDEX 提供程序 3.0.1（来自 msi），可以通过 VS 进行数据操作。

我在位置 C:\Windows\Microsoft.NET\assembly\GAC_MSIL\FirebirdSql.Data.FirebirdClient\v4.0_4.6.4.0__3750abcc3150b00c 检查了 GAC 正如预期的那样 FirebirdSql.Data.FirebirdClient.dll。

不幸的是，我在服务器资源管理器中尝试设置新数据连接时遇到错误 "Unable to find the requested .NET Framework Data Provider. It may not be installed"。

我多次尝试安装和卸载提供商，但没有帮助。

以下是我的 machine.config 文件中的代码： C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config

<system.data>
    <DbProviderFactories><add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/><add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=4.6.4.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"/><add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=4.6.4.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"/></DbProviderFactories>
</system.data>

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

<system.data>
    <DbProviderFactories><add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/><add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=4.6.4.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"/><add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=4.6.4.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"/></DbProviderFactories>
</system.data>

任何帮助将不胜感激。

您收到错误 "Unable to find the requested .NET Framework Data Provider. It may not be installed"，因为您在 machine.config 中有第二个 firebird 条目。发生这种情况是由于 to a bug in the installer 仍未解决。

使用Firebird 3.0时出现"connection rejected by remote interface"错误，可能是因为3.0新的认证方式。在这里你必须降级到 2.5.4，enable the old legacy authentication 或等待 .Net 提供商的更新以完全支持 Firebird 3.0，包括新的身份验证。
