WPF App Using new csproj format
提问by Mark Olbert
I am experimenting with migrating a WPF project, defined using the old csproj format, to the new format under VS 2017.
我正在尝试将使用旧 csproj 格式定义的 WPF 项目迁移到 VS 2017 下的新格式。
I was able to get most of the way to a successful build using information I found at How-to migrate Wpf projects to the new VS2017 format.
我能够使用我在How-to migrate Wpf projects to the new VS2017 format 中找到的信息获得成功构建的大部分方式。
But I'm stuck at getting past this error:
但我坚持克服这个错误：
error CS5001: Program does not contain a static 'Main' method suitable for an entry point
错误 CS5001：程序不包含适合入口点的静态“Main”方法
My new-style csproj file is as follows:
我的新式csproj文件如下：
<Project Sdk="Microsoft.NET.Sdk">

How do I configure the csproj file so that entry point gets built?
如何配置 csproj 文件以便构建入口点？

Based on the tip about ApplicationDefinition I was able to get the project to compile. I could not set ApplicationDefinition in the BuildAction -- it was not one of the choices -- but had to edit the csproj file manually to include it. Here's the working version:
根据有关 ApplicationDefinition 的提示，我能够编译项目。我无法在 BuildAction 中设置 ApplicationDefinition——它不是选择之一——但必须手动编辑 csproj 文件以包含它。这是工作版本：
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<LanguageTargets>$(MSBuildExtensionsPath)$(VisualStudioVersion)\Bin\Microsoft.CSharp.targets</LanguageTargets>
<OutputType>winexe</OutputType>
<TargetFramework>net47</TargetFramework>
<ApplicationIcon />
<OutputTypeEx>winexe</OutputTypeEx>
<StartupObject />
</PropertyGroup>
<ItemGroup>
<EmbeddedResource Update="Properties\Resources.resx" Generator="ResXFileCodeGenerator" LastGenOutput="Resources.Designer.cs" />
<Compile Update="Properties\Resources.Designer.cs" DesignTime="True" AutoGen="True" DependentUpon="Resources.resx" />
<Compile Update="Settings.Designer.cs" AutoGen="True" DependentUpon="Settings.settings" />
<None Update="Settings.settings" LastGenOutput="Settings.Designer.cs" Generator="SettingsSingleFileGenerator" />
<Page Include="**\*.xaml" SubType="Designer" Generator="MSBuild:Compile" Exclude="App.xaml" />
<Compile Update="**\*.xaml.cs" SubType="Designer" DependentUpon="%(Filename)" />
<Resource Include="assets\*.*" />
<ApplicationDefinition Include="App.xaml">
<Generator>MsBuild:Compile</Generator>
<SubType>Designer</SubType>
</ApplicationDefinition>
</ItemGroup>
<ItemGroup>
<PackageReference Include="Autofac" Version="4.6.0" />
<PackageReference Include="Autofac.Extras.CommonServiceLocator" Version="4.0.0" />
<PackageReference Include="Extended.Wpf.Toolkit" Version="3.0.0" />
<PackageReference Include="Hardcodet.NotifyIcon.Wpf" Version="1.0.8" />
<PackageReference Include="MaterialDesignColors" Version="1.1.3" />
<PackageReference Include="MaterialDesignThemes" Version="2.3.0.823" />
<PackageReference Include="MvvmLightLibs" Version="5.3.0" />
<PackageReference Include="Serilog" Version="2.4.0" />
<PackageReference Include="Serilog.Sinks.RollingFile" Version="3.3.0" />
</ItemGroup>
<ItemGroup>
<ProjectReference Include="..\..\WPFUtilities\J4JUI\J4JUI.csproj" />
</ItemGroup>
<ItemGroup>
<Reference Include="System.ComponentModel.DataAnnotations" />
</ItemGroup>
<Import Project="$(MSBuildSDKExtrasTargets)" Condition="Exists('$(MSBuildSDKExtrasTargets)')" />
</Project>
Note also the Exclude filter on the directive. It's necessary to keep MSBuild from attempting to compile App.xaml.cs twice.
还要注意指令上的排除过滤器。有必要阻止 MSBuild 尝试编译 App.xaml.cs 两次。

You need to set the Build Action of App.xamlto ApplicationDefinition. The result is the following item in your csprojfile:
您需要将 Build Action 设置App.xaml为 ApplicationDefinition。结果是您的csproj文件中的以下项目：
<ApplicationDefinition Include="App.xaml">
<Generator>MSBuild:Compile</Generator>
<SubType>Designer</SubType>
</ApplicationDefinition>
