在一个新创建的asp项目中 在：Generate Databases from Model...中选择数据库连接后，单击“下一步”后，将显示异常： image

我想我有the provider is registered in the 'entityFramework' section of the application config

我安装了Oracle.ManagedDataAccess和Oracle.ManagedDataAccess。通过从nuget安装Oracle.ManagedDataAccess.EntityFramework。

  <package id="Oracle.ManagedDataAccess" version="12.1.2400" targetFramework="net452" />
  <package id="Oracle.ManagedDataAccess.EntityFramework" version="12.1.2400" targetFramework="net452" />

这是我的web.config：

您是否将模型ddl生成从MS Sql更改为Mysql？
如果没有，请转到：
型号＆gt;属性＆gt;数据库脚本生成＆gt;
