>我刚刚安装了VS2017,并将我的.NET核心项目从project.json格式单向迁移到新的csproj格式。我想要的是针对多个框架,以便我可以使用较小的占用空间构建框架设计部署和独立部署。我遵循了 MS 文档中的说明,但是当我在 TargetFramework 中包含 netstandard1.6 或 netstandard2.0 时,当我尝试构建项目时,我会得到一大堆Predefined type System.Object is not defined
和The type of namespace System could not be found
等等。当它使用 project.json 文件时,这有效。我的csproj是
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<VersionPrefix>1.0.0.0</VersionPrefix>
<TargetFrameworks>netcoreapp1.2;netstandard2.0</TargetFrameworks>
<AssemblyName>App</AssemblyName>
<OutputType>Exe</OutputType>
<PackageId>App</PackageId>
<RuntimeFrameworkVersion Condition=" '$(TargetFramework)' == 'netcoreapp1.2' ">1.1.1</RuntimeFrameworkVersion>-->
<NetStandardImplicitPackageVersion Condition=" '$(TargetFramework)' == 'netstandard2.0' ">1.6.1</NetStandardImplicitPackageVersion>
<RuntimeIdentifiers>win10-x64;android.21;android21-arm64;osx.10.12;rhel7.4;centos.7-x64;debian8-x64;ubuntu16.10-x64;fedora.26-x64;opensuse.42.1-x64</RuntimeIdentifiers>
<GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute>
<GenerateAssemblyCompanyAttribute>false</GenerateAssemblyCompanyAttribute>
<GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute
</PropertyGroup>
<ItemGroup>
<None Remove="App.csproj.vspscc" />
</ItemGroup>
<ItemGroup Condition=" '$(TargetFramework)' == 'netstandard2.0' ">
<PackageReference Include="System.Threading.Thread" Version="4.3.0" />
<PackageReference Include="Microsoft.NETCore.Runtime.CoreCLR" Version="1.1.0" />
</ItemGroup>
</Project>
我的原始项目.json
{
"version": "1.0.0.0",
"buildOptions": {
"emitEntryPoint": true
},
"frameworks": {
"netcoreapp1.2": {
"dependencies": {
"Microsoft.NETCore.App": {
"type": "platform",
"version": "1.1.0"
}
}
},
"netstandard2.0": {
"dependencies": {
"NETStandard.Library": {
"version": "1.6.1"
},
"System.Threading.Thread": "4.3.0",
"Microsoft.NETCore.Runtime.CoreCLR": "1.1.0"
}
}
},
"runtimes": {
"win10-x64": {}
"ubuntu.16.10-x64": {},
"centos.7-x64": {},
"debian.8-x64": {},
"fedora.24-x64": {},
"opensuse.42.1-x64": {},
"osx10.12-x64" : {}
}
}
不知道问题是什么。我是否正在尝试做一些不受支持的事情?如果我只有netcoreapp1.2,当我做dotnet publish -c Release -r win10-x64时,我仍然得到FDD输出,而不是独立的可执行文件。我觉得使用 json 文件这更容易......我做错了什么?
当Nuget包未还原时,我收到相同的错误消息。是否已确保包已正确还原,并且在运行"dotnet 还原"时不会出现任何错误?
