ASP.NET Core 2.0 Entityfarmework Core错误Ubuntu

Question

Iam about to publish my ASP.NET Core 2.0 Web-Api on my Raspberry pie. Running my application local on my Windows 10 machine works great, but when I deploy it to the Raspberry (ubuntu.16.04-arm), I have problems with entity-framework.

As soon as a databaseoperation is executed, Iam getting the following error:

fail: Microsoft.EntityFrameworkCore.Query[100100] An exception occurred in the database while iterating the results of a query for context type 'NFCDataRESTApi.SQLiteDataBase.DataBase'.

The intersting part probably is:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.DllNotFoundException: Unable to load DLL 'e_sqlite3': The specified module or one of its dependencies could not be found.

Iam using entity framework core

Any advices?

Edit:

My csproj:

  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />
    <PackageReference Include="SQLitePCL.raw" Version="0.9.4-pre1" />
    <PackageReference Include="Swashbuckle.AspNetCore" Version="1.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="2.0.0" />
 </ItemGroup>

if dotnet restore didn't work: possibly you need local/linux libraries on which the nuget package depends on?

You can install sqllite through app-get. Allthough i don't think this would be necessary. But I had http/ssl issues before on dotnet docker image, i had to install extra linux libraries.
