Visual Studio上Winexe应用被引用编译时自动转为library

发表于

起因

WinFormsApp1和WinFormsApp2都是Windows应用程序(WinExe)，WinFormsApp2引用了WinFormsApp1。当发布WinFormsApp2时，会提示“未能找到元数据文件”xxxx\xxxx\WinFormsApp1.dll””。如果在项目属性中将WinFormsApp1输出类型改为类库(Library)则WinFormsApp2可以正确发布。缺点是每次发布或者调试WinFormsApp1都需要将输出类型改回WinExe。

方案

编辑WinFormsApp1.csproj，创建BuildAsLibrary属性，并配置OutputType在BuildAsLibrary=true时输出Library,在BuildAsLibrary=false时输出WinExe

WinFormsApp1.csproj

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

  <PropertyGroup>
    <!-- <OutputType>WinExe</OutputType> -->
    <BuildAsLibrary>false</BuildAsLibrary>
    <OutputType Condition="'$(BuildAsLibrary)' == 'true'">Library</OutputType>
    <OutputType Condition="'$(BuildAsLibrary)' != 'true'">WinExe</OutputType>
    <TargetFramework>net8.0-windows</TargetFramework>
    <Nullable>enable</Nullable>
    <UseWindowsForms>true</UseWindowsForms>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

</Project>

编辑WinFormsApp2.csproj，修改WinformsApp1的ProjectReference，设置BuildAsLibrary=true

    <UseWindowsForms>true</UseWindowsForms>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <ProjectReference Include="..\WinFormsApp1\WinFormsApp1.csproj" Properties="BuildAsLibrary=true" />
  </ItemGroup>

</Project>

至此，WinFormsApp1和WinFormsApp2可以各自发布成对应的WinExe程序!问题解决!~
