VS 2017 RC asp.net核心system.net.http衝突問題

我一直在研究.net核心web應用程序大約3個月。隨着VS2017的發佈，我認爲我會在本週末試用它的自動遷移以及新的環境。當我這樣做的時候，除了System.Net.Http引用之外，一切都進展順利。VS 2017 RC asp.net核心system.net.http衝突問題

我收到一個錯誤，指出;

1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(1956,5): warning MSB3243: No way to resolve conflict between "System.Net.Http, Version=4.1.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Net.Http, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". Choosing "System.Net.Http, Version=4.1.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" arbitrarily. 
1>Consider app.config remapping of assembly "System.Net.Http, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" from Version "1.5.0.0" [C:\Users\reamj\.nuget\packages\microsoft.net.http\2.2.22\lib\portable-net40+sl4+win8+wp71+wpa81\System.Net.Http.dll] to Version "4.1.1.0" [C:\Users\reamj\.nuget\packages\system.net.http\4.3.0\ref\netstandard1.3\System.Net.Http.dll] to solve conflict and get rid of warning.

因爲這是在DLL中，我真的不知道如何解決這個問題。這將是很好的解決這個利用VS17。任何幫助是極大的讚賞！下面是我的csproj（不再是project.json）配置。

在與此namespa相關的corefx GitHub repo上搜索問題ce，你應該知道什麼是解決方案。 –

嘗試...

（1）刪除<PackageReference Include="Microsoft.AspNet.WebApi.Client" Version="5.2.3" /> （你不應該需要這個包在.NET內核上運行的WebAPI。）

（2 ）將SendGrid更改爲<PackageReference Include="Sendgrid" Version="9.0.12" />
