我制作了一个基于 docker 容器microsoft/dotnet:1.0-sdk。按照指南，我执行了dotnet new console并得到一个文件dotnet.csproj. dotnet restore and dotnet run worked.
现在我想添加我的真实代码，这取决于 YamlDotNet。所以我像这样编辑了项目文件：
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp1.1</TargetFramework>
<EnableDefaultCompileItems>false</EnableDefaultCompileItems>
</PropertyGroup>
<ItemGroup>
<Compile Include="Yaml2Events.cs"/>
</ItemGroup>
<Import Project="..\..\YamlDotNet\YamlDotNet\YamlDotNet.csproj"/>
</Project>
..\..\YamlDotNet是 YamlDotNet 签出的路径。请不要评论使用 NuGet 包或其他东西，我want以获得最新版本。
现在当我尝试dotnet run，我收到此错误：
/usr/share/dotnet/sdk/1.0.1/Sdks/Microsoft.NET.Sdk/Sdk/Sdk.targets(40,3): warning MSB4011: "/usr/share/dotnet/sdk/1.0.1/Microsoft.CSharp.targets" cannot be imported again. It was already im

I guess发生这种情况是因为在YamlDotNet.csproj，有这一行：
<TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
根据错误，我猜这个版本不可用，所以我需要修补该文件。我只是删除了该行，这使得错误更改为：
/usr/share/dotnet/sdk/1.0.1/Sdks/Microsoft.NET.Sdk/Sdk/Sdk.targets(40,3): warning MSB4011: "/usr/share/dotnet/sdk/1.0.1/Microsoft.CSharp.targets" cannot be imported again. It was already im

现在我不知所措了。不知道参考在哪里".NETFramework,Version=v4.0"来自，我没有找到它YamlDotNet.csproj。另外，我感觉我正在做一些根本错误的事情，因为我不需要修改另一个项目文件就可以导入它，对吧？
那么，导入现有项目以使用 .NET Core 工具进行挖矿的正确方法是什么？
