Platform not supported errors since update from 2.3.0-beta5 to 2.3.0-rc1

[axelheer]

Since upgrading to the newest version all integration tests using sql connections fail with:

System.NotSupportedException : The keyword 'integrated security' is not supported on this platform.

Repro:

using System;
using System.Data.SqlClient;
using Xunit;

namespace XUnitIssue
{
    public class UnitTest1
    {
        [Fact]
        public void Test1()
        {
            var connectionString = @"Data Source=(LocalDB)\MSSQLLocalDB; Initial Catalog=master; Integrated Security=true;";

            new SqlConnection(connectionString).Open();
        }
    }
}

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="System.Data.SqlClient" Version="4.3.1" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
    <PackageReference Include="xunit" Version="2.3.0-rc1-build3809" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.0-rc1-build3809" />
  </ItemGroup>

  <ItemGroup>
    <DotNetCliToolReference Include="dotnet-xunit" Version="2.3.0-rc1-build3809" />
  </ItemGroup>

</Project>

Notes:

• executing dotnet test succeeds, only dotnet xunit fails
• changing the version numbers back to 2.3.0-beta5-build3769 solves the problem

What target platform (OS, .NET SDK version #, etc.) are you running this on?

[axelheer]

Windows 7, .NET Core 1.1.4, .NET Core SDK 2.0.0

Found the bug... it was trying to use the unix version of the SqlClient assembly instead of the win version. Glad you caught this! Thanks!

Hmm, not quite finished yet:

System.DllNotFoundException : Unable to load DLL 'sni.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Finally got it figured out, once again due to the awesomeness of @natemcmaster. :) This will be fixed in RC 2.

Failing on appveyor too (with different message) https://ci.appveyor.com/project/andreabalducci/nstore/build/1.0.418

Working build (2.3.0 beta1)

@andreabalducci Please open an new issue with a repro project.

[bradwilson]

Also, your AppVeyor error is unrelated, and is actually this non-bug: #1573
