c# - ASP.Net 无法找到 .Net Framework 提供程序

Question

在将网站上传到 Godaddy 服务器的过程中，使用 MySql 的数据网格引发了问题。错误与 Web 配置一起输出如下。问题似乎是服务器没有正确安装的要求，例如我的 Web 配置中的 MySql.Data，但我不确定该怎么办。 .Net MySql 连接器安装在本地系统上并且运行良好。这是输出的错误。

Answer 1

您可能需要对数据提供程序进行 bin 部署。 This来自 GoDaddy 的链接描述了如何 bin 部署 ASP.NET MVC dll，但对于包含数据提供程序的 MySQL DLL，该过程应该类似(即 copy-local 应设置为 true)。

抱歉，如果我没有走上正轨。
