从数据库使用EntityFramework C＃代码优先-如何在没有主键的情况下映射表

Question

I am building an Ntier application with EntityFramework c#. I am adding an Entity Data Model in my Data Access Layer with code-first approach from existing database.

Some of the tables of my db weren't included because they don't have primary key. I have seen some ways to work around this problem, modifying EntityFramework's edmx to force the mapping to the database, disguising some field like a key. But I am not using the .edmx, since I can't use automatic migrations with it. I only generate POCOs from my existing database and then go on with code first migrations.

Is there a way to force Entity Framework to generate a POCO for those tables without primary key ? Some only have one entry and really don't need PrimaryKey

Answer 1

In the end, I just wrote my own POCOs for the tables that weren't included.

I used an attribute [KEY] above the property i wanted to act like key. I added DbSet lines in the DataModel and EF did recognize them in my database.

I didn't want to generate primary keys because my boss didn't want, and thats a reason good enough. :) Hope the best for you thx for answer
