推荐答案

有相当多的谷歌搜索结果有可能修复。这是你必须要解决的问题，因为不仅有一个修复。



但是，我建议从这篇文章开始： http://stackoverflow.com/questions/6553935/ef-code-first- invalid-column-name-discriminator-but-no-inheritance [ ^ ]

There are quite a few google results that have potential fixes. It's something you'll have to troubleshoot on your end since there is not just one fix.

However, I suggest starting with this article: http://stackoverflow.com/questions/6553935/ef-code-first-invalid-column-name-discriminator-but-no-inheritance[^]

这不是一个简单的主题，在解决我自己的问题时，我出现了以下文章解释了各种可能的类型映射。它可能有助于诊断找到此页面的人的不同场景和可能的修复：

This is not a simple subject and while troubleshooting my own issue, I came up with the article below, which explains the various possible type mappings. It may help to diagnose the different scenarios and possible fixes for people who find this page:
