@voronoipotato构建 .csproj 文件，而不是解决方案文件。解决方案似乎包含 Mac 项目，并且始终无法在 Linux 上构建。

注意：不建议这样做，因为某些功能缺失或无法在 net core 上运行，例如 WebView。 @cra0zy可以告诉你更多。

不......一切都适用于 .NET Core，包括 WebView。

感谢您报告问题。但是，您需要使用msbuild而不是dotnet build 。

cwensley 于 2018-04-06

那行得通。当我为 F# 尝试同样的事情时
dotnet new etoapp -g -sln -lang F#
然后我得到

与 msbuild。

我们可能应该将不能使用 dotnet build 的内容添加到快速入门指南中。

voronoipotato 于 2018-04-06

@voronoipotato nuget restore 。
NuGet 命令应该与 mono-complete 一起安装，但如果不是，您可以单独安装它。

如果您只需要支持 Linux 平台，您可以使用Eto.Platform.Gtk nuget 并以 netcoreapp2.0 为目标，您将能够使用dotnet build构建

这是我的 csproj 的示例：

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Eto.Platform.Gtk" Version="2.4.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Eto.Desktop\Eto.Desktop.csproj" />
  </ItemGroup>

</Project>

注意：不建议这样做，因为某些功能缺失或无法在网络核心上运行，例如WebView 。

实际上，这是不正确的。 mac 项目不再使用已弃用的 MonoMac 项目类型，而是使用 sdk 样式的 csproj。 Eto 的 nuget 包现在包含 .targets 文件，这些文件将在 Windows 或 Linux 上为您构建 .app 包。但是，可选的 Xamarin.Mac 项目仍将仅在 Mac 上构建。

cwensley 于 2018-04-06

完毕！我在示例中添加了nuget restore和msbuild以将人们指向正确的方向。

cwensley 于 2018-04-06

啊，我以为他正在生成每个平台的解决方案，还没有真正尝试过新的模板。

harry-cpp 于 2018-04-06

@voronoipotato现在使用 nuget/msbuild 对你有用吗？

我还创建了#1080 来移植 .targets 文件以在将来支持dotnet build 。

cwensley 于 2018-04-12

我也无法建立一个微不足道的案例。

该错误已经告诉您出了什么问题...“运行 NuGet 包还原以生成此文件。”，不，这并不意味着运行nuget restore ，该命令不能那样工作。最简单的解决方案是运行dotnet restore 。

harry-cpp 于 2018-04-13

根据Package Restore 上的文档，它也由nuget restore触发。无论如何，运行dotnet restore会导致部分错误：

[…]/eto-test/eto-test.Desktop/eto-test.Desktop.fsproj(57,3): error MSB4020: The value "" of the "Project" attribute in element <Import> is invalid.
[…]/eto-test/eto-test.Desktop/eto-test.Desktop.fsproj : warning NU1503: Skipping restore for project '[…]/eto-test/eto-test.Desktop/eto-test.Desktop.fsproj'. The project file may be invalid or missing targets required for restore. [[…]/eto-test/eto-test.sln]
[…]

这似乎在运行msbuild时会导致问题：

根据包还原的文档，它也由 nuget restore 触发。

nuget restore需要用于恢复目录和项目文件的参数才能工作，这就是我所说的，没有它们你不能运行它（除非它被任何机会改变）。

harry-cpp 于 2018-04-13

看起来我的问题是$(FSharpTargetsPath)是空的。这并不奇怪，因为.fsproj文件在设置此变量时似乎假设已安装 Visual Studio：

<Choose>
  <When Condition="'$(VisualStudioVersion)' == '11.0'">
    <PropertyGroup Condition=" '$(FSharpTargetsPath)' == '' AND Exists('$(MSBuildExtensionsPath32)\..\Microsoft SDKs\F#\3.0\Framework\v4.0\Microsoft.FSharp.Targets') ">
      <FSharpTargetsPath>$(MSBuildExtensionsPath32)\..\Microsoft SDKs\F#\3.0\Framework\v4.0\Microsoft.FSharp.Targets</FSharpTargetsPath>
    </PropertyGroup>
  </When>
  <Otherwise>
    <PropertyGroup Condition=" '$(FSharpTargetsPath)' == '' AND Exists('$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\FSharp\Microsoft.FSharp.Targets') ">

是的，作为一个测试用例，在具有 dotnet 核心和单声道的干净 vm 上运行以查看构建它真正需要的东西可能是一个好主意。

voronoipotato 于 2018-04-16

@cra0zy dotnet restore不支持 F# 模板所需的 packages.config。但是，我刚刚意识到 nuget 上的模板尚未更新到 2.4.1（它们是 2.4.0），我删除了 packages.config 要求，因为 F# 工具现在可以正确支持它。
