我遇到了同样的问题(我也在使用EF7和其他库)，但是我使用后，我已经解决了所有问题.EF核心也可以通过nuget获得

I have a solution where my main project is a uwp app, and two other projects referenced by the app :

1. UWP App ---> references 2.
2. Universal Class library ----> references 3.
3. PCL Library

2 --> uses EF7 and SQLight.

3 --> uses PCLCrypto

Now, everything works just fine and excellent when I'm on Debug mode x86 targeting local machine.

I want to compile the solution in release mode using .Net native tool chain, here's my config :

When I launch the compilation, it takes a remarkably long time, and too much memory is consumed by the .Net native tools :

After some time, everything stops with 2 errors on visual studio :

Here's what the output window says :

1>------ Build started: Project: ServerCommunication, Configuration: Release Any CPU ------ 1> ServerCommunication -> C:\Users\aymen\Documents\Visual Studio 2015\Projects\Applinova\Liberte\ServerCommunication\bin\Release\ServerCommunication.dll 2>------ Build started: Project: NewspaperDataLayer, Configuration: Release x86 ------ 2>C:\Users\aymen\Documents\Visual Studio 2015\Projects\Applinova\Liberte\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets(225,5): warning : All projects referencing ServerCommunication.csproj must install nuget package Microsoft.Bcl.Build.

3>------ Build started: Project: Liberte, Configuration: Release x86

--some warnings here that I just skipped

What would possibly be wrong with this please ??

I had the same problem (I am also using EF7 and other libraries) but I solved using Visual Studio 15 preview (it is not visual studio 2015 update 2, which I didn't try). They improved the .NET native tools so now you should not have any problem, even if using a lot of third party library.

UPDATE

I have solved all my issues after i have installed visual studio 2015 update 3 and switched from EF7 to EF core also available via nuget
