Asp.Net Core Full Framework compile error

I created ASP.NET Core .Net Web Application (.Net Framework) and reference Data library

In Data library, i added Microsoft.EntityFrameworkCore.Sqlite from Nuget Package Manager

When i build, i got error "Failed to make the following project runnable: SiteApp (.NETFramework,Version=v4.5.2) reason: The process cannot access the file '\packages\sqlite.3.13.0\runtimes\win7-x64\native\sqlite3.dll' because it is being used by another process.".

If i remove Data library, add all class to site app and added Microsoft.EntityFrameworkCore.Sqlite it works 

How i seperate to Data library?
