The second exception complains about mapping column used for condition to a property. Once you use any column for condition you cannot have it mapped to property (except the situation when the condition is IsNull=False). The column is already used to map entity type and no column can be used in mapping twice. share|improve this answer answered Jun 21 '12 at 10:39 Ladislav Mrnka 283k43521582 Sory but can you guide me where i am doing mapping twice? –user1387147 Jun 21 '12

I've created a new project in VS2015 - a 'ASP.NEt 5 Preview Template' Web API. Then I used the Package Manager Console to add Entity Framework (Install-Package EntityFramework) Then I tried creating a context class that inherits from DbContext. I'm getting errors on my 'using System.Data.Entity' line. When I mouse over it, it tells me that it is available for DNX 4.5.1 but not DNX Core 5.0 Resharper also identifies the entity framework error line as invalid. 'The type or namespace name 'Data' does not exist in the namespace 'System' (are you missing an assembly reference?) BuildWatcherAPI.DNX Core 5.0 I've tried manually adding references to System.Data/System.Data.Entity but that doesn't seem to do the trick. Clearly I'm doing something very wrong - can anyone point me in the right direction? What's extra strange is that I've done this from scratch again, and that solution seems to build fine. So I must have done something else, inadvertently, but I'm having trouble seeing any differences between the two solutions and I'd like to understand what went wrong. c# asp.net entity-framework asp.net-web-api share|improve this question asked Sep 10 '15 at 2:23 Rob P. 8,86694885 Have you tried to delete bin and obj folder, then clean+rebuild the solution again? –Fabio Luz Sep 10 '15 at 2:44 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted You have to either remove the "dnxcore50" line from your project.json because EF6 doesn't support .Net Core or upgrade to EF7. This answer gives more details. share|improve this answer answered Sep 10 '15 at 10:13 Julien Lebot 2,6241227 add a comment| up vote 0 down vote Which framework version are you using? I'd say that you may change your framwork version to 4.5 and rebuild your project.
