Oracle.ManagedDataAccess.Client could not be loaded.

Question

连接sqlserver的时候很正常，连接oracle就报错。

System.InvalidOperationException:“The Entity Framework provider type
'Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices,
Oracle.ManagedDataAccess.EntityFramework, Version=6.121.2.0,
Culture=neutral, PublicKeyToken=89b483f429c47342' registered in the
application config file for the ADO.NET provider with invariant name
'Oracle.ManagedDataAccess.Client' could not be loaded. Make sure that
the assembly-qualified name is used and that the assembly is available
to the running application. See
http://go.microsoft.com/fwlin... for more information.”

用了里面提到的方法依然不行。

据说是直接从 nuget 上面 down 下来的包不行，要直接到 oracle 官网上取下 ……

有遇到过这种问题吗？
