Question

在我的.NET 4.7.2类库项目中，我添加了“ Oracle.ManagedDataAccess.EntityFramework” nuget包。访问DbContext时

using (var ctx = new BdeDbContext())

我正在获取“在ADO的应用程序配置文件中注册的实体框架提供程序类型'Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices，Oracle.ManagedDataAccess.EntityFramework，Version = 6.122.18.3，Culture = neutral，PublicKeyToken = 89b483f429c47342'无法加载具有不变名称'Oracle.ManagedDataAccess.Client'的.NET提供程序。请确保使用了程序集限定名称，并且该程序集可用于正在运行的应用程序。”

在看了类似的文章之后，我还添加了“ Visual Studio 2017的ODAC”和“ odp.net.x64”，但这没有帮助。有人有类似的问题吗？

我的app.config如下所示。
