Oracle Data Provider for .NET 升级后不支持 Oracle 19.0.48.0.0
我有一个在Asp.net中构建的应用程序，我们将oracle数据库升级到19c“我们在oracle 11g上工作”，首先给我们以下错误：
无法安装包“Oracle.ManagedDataAccess 21.5.0”。您正在尝试将此包安装到面向“.NETFramework，Version=v4.5”的项目中，但该包不包含任何与该框架兼容的程序集引用或内容文件。如需了解更多信息，请联系软件包作者。
搜索后，我发现Oracle.ManagedDataAccess 21.5.0需要.NET Framework版本5。
无论如何，我将所有项目的目标框架从4.5升级到4.7。 2 然后这个问题就不再出现了。
之后，我尝试安装 Oracle.ManagedDataAccess 19.13.0 并且安装成功，但是当我尝试登录“需要连接到数据库”时，它给我错误消息：
Oracle Data Provider for .NET 不支持 Oracle 19.0.48.0.0
我尝试清理解决方案并重建它，但它没有解决问题。
I have an application built in Asp.net, we upgraded the oracle database to 19c "where we were working on oracle 11g", first give us the below error:
Could not install package 'Oracle.ManagedDataAccess 21.5.0'. You are trying to install this package into a project that targets '.NETFramework, Version=v4.5', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
After searching I found the Oracle.ManagedDataAccess 21.5.0 requires .NET Framework version 5.
Anyway, I upgrade the target framework for all projects from 4.5 to 4.7.2 and that issue didn't appear anymore.
After that, I tried to install Oracle.ManagedDataAccess 19.13.0 and it was installed successfully but when I try to login "need to connect to the database" it give me the error message:
Oracle Data Provider for .NET does not support Oracle 19.0.48.0.0
I tried to clean the solution and rebuild it, but it didn't fix the problem.

通常，

将目标框架升级到 .NET Framework 4.6.2 或更高版本即可解决此问题。无需使用旧版本的包。

Upgrading your target framework to .NET Framework 4.6.2 or later is the fix. No need to use an old version of the package.
