我是从一个字preSS数据库，该数据库中的主键定义为十进制，我使用该项目的64位配置...

位我搜索我发现它的问题，但我无法找到一个解决方案。

我有什么做/下载到能够使用十进制作为主键？

如果你只从表中读取数据，你可以尝试创建蒙上领域为int的视图，那么你的实体映射到视图。

除此之外，我认为你是pretty的多倒霉。这是在实体框架中的错误;要么改变字段类型，从EF转走，或等待MS修复的bug。

I am retrieving data from a wordpress database which defines the primary key as decimal and I am using a x64 configuration on the project...

The bit I searched I found out that it is the problem, but I couldn't find a solution.

What do I have to do/download to be able to use decimal as a primary key?

If you're only reading data from the table you can try creating a view that casts the field to an int and then map your entity to the view.

Beyond that, I think you're pretty much out of luck. This is a bug in Entity Framework; either change the field type, switch away from EF, or wait for MS to fix the bug.
