带有 dnx 项目的 EF 6

问题描述

I have a new ASP.net 5 dnx class library I am using for entity framework. I need to target EF 6 because some features I need are not in EF 7.

First the EF tools (like enable-migration) were not there. I added an old style class library and installed EF 6 and now the commands are there.

When I run enable migrations I get this error:

I have tried different options for enable-migration such as specifying a startup project or the contextTypeName.

Any ideas?

解决方案

Following this recommendation, EF6 data projects should use the existing .NET Framework class library csproj type.

Even after following the recommendations, I was still getting the same error. Unloading your ASP.NET Core project(s) and then invoking the Enable-Migrations command on the appropriate csproj should allow the command to execute. You can unload a project by right-clicking on the .NET Core project and choosing the 'Unload Project' option. It should also be noted that the Package Manager Console window has a 'Default project:' drop-down selection. You should choose the project with your DbContext.
