title: .Net Core 2.0 Warning NU1603 during dotnet restore, problems with NuGet packages
body: <p>(world!)</p>
  
  <p>I am writing application APS .Net Core 2.0. In Test project after adding some NuGet packages to .csproj I meet some troubles. At the command <code>dotnet restore</code> an error pops up:</p>
  
  <blockquote>
    <p>D:\01_Toci\100_GIT\Passenger\Passenger.Tests\Passenger.Tests.csproj :
    warning NU1603: Castle.Core 4.0.0 depends on
    System.ComponentModel.TypeConverter (>= 4.0.1) but
    System.ComponentModel.TypeConverter 4.0.1 was not found. An
    approximate best match of System.ComponentModel.TypeConverter 4.1.0
    was resolved.</p>
  </blockquote>
  
  <p>There is my .csproj code:</p>
  
  <pre><code>&lt;Project Sdk="Microsoft.NET.Sdk"&gt;
  
    &lt;PropertyGroup&gt;
      &lt;TargetFramework&gt;netcoreapp1.1&lt;/TargetFramework&gt;
      &lt;AssemblyName&gt;Passenger.Tests&lt;/AssemblyName&gt;
      &lt;PackageId&gt;Passenger.Tests&lt;/PackageId&gt;
      &lt;GenerateRuntimeConfigurationFiles&gt;true&lt;/GenerateRuntimeConfigurationFiles&gt;
      &lt;PackageTargetFallback&gt;$(PackageTargetFallback);dnxcore50&lt;/PackageTargetFallback&gt;
      &lt;RuntimeFrameworkVersion&gt;1.1.1&lt;/RuntimeFrameworkVersion&gt;
    &lt;/PropertyGroup&gt;
  
    &lt;ItemGroup&gt;
      &lt;ProjectReference Include="../Passenger.Core/Passenger.Core.csproj" /&gt;
      &lt;ProjectReference Include="../Passenger.Infrastructure/Passenger.Infrastructure.csproj" /&gt;
    &lt;/ItemGroup&gt;
  
    &lt;ItemGroup&gt;
      &lt;PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" /&gt;
      &lt;PackageReference Include="xunit" Version="2.2.0" /&gt;
      &lt;PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" /&gt;
      &lt;PackageReference Include="FluentAssertions" Version="4.19.0" /&gt;
      &lt;PackageReference Include="Moq" Version="4.7.8" /&gt;
      &lt;PackageReference Include="dotnet-test-nunit" Version="3.4.0-beta-3" /&gt;
    &lt;/ItemGroup&gt;
  
  &lt;/Project&gt;
  </code></pre>
  
  <p>and <a href="https://pastebin.com/1MszQsMe" rel="nofollow noreferrer">project.assert.json</a> (it's too long, so i decide to use pastebin)</p>
  
  <p>I tried to change versions in the json file, </p>
  
  <pre><code>"System.ComponentModel.TypeConverter": "4.1.0",
  </code></pre>
  
  <p>and many other options, but nothing has been done...I was stuck. I got mixed up with these nuggets and I do not know how to get out of it.</p>
  
  <p>Please help me.</p>
