打破微软封印面向未来创建.NET Framework4.8工程

摘要：

1. 工程从.NET Framework 4.8升级到.NET 8.0，即使采用官方方案也是很繁琐的一件事情，而且容易出问题。
2. Windows 11内置了.NET Framework 4.8，所以当前的软件需要基于.NET Framework 4.8。但后续微软推出Windows 12，将内置更高版本的.NET版本，如何让软件跟随微软步伐快速平稳升级？
3. 本文叫你如何打破微软封印，在VS2022中如何高屋建瓴面向未来优雅地创建.NET Framework 4.8工程。

关键工作流程：

1. 创建新项目，【WPF 应用程序】

2. 选择框架【.NET 8.0（长期支持）】

3. 基于.NET 8.0的工程文件【HAPTICCAL.csproj】

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

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net8.0-windows</TargetFramework>
    <Nullable>enable</Nullable>
    <UseWPF>true</UseWPF>
    <RootNamespace>FirstSolver</RootNamespace>
    <ApplicationIcon>$(AssemblyName).ico</ApplicationIcon>
    <ProduceReferenceAssembly>False</ProduceReferenceAssembly>
    <Authors>秦建辉</Authors>
    <AssemblyVersion>4.3.0</AssemblyVersion>
    <FileVersion>$(AssemblyVersion)</FileVersion>
    <NeutralLanguage>zh-Hans</NeutralLanguage>
    <StartupObject>FirstSolver.Program</StartupObject>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="C2VColorEdit" Version="3.0.0" />
    <PackageReference Include="C2VLanguage" Version="3.0.0" />
    <PackageReference Include="HPSocket.Net" Version="5.9.3.1" />
    <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
    <PackageReference Include="NLogHelper" Version="3.0.0" />
    <PackageReference Include="NLogViewer" Version="3.0.0" />
    <PackageReference Include="TF_Communication_CS" Version="3.0.4" />
  </ItemGroup>

  <ItemGroup>
    <Resource Include="..\TF.png" Link="TF.png" />
    <Resource Include="$(AssemblyName).ico" />
  </ItemGroup>

  <ItemGroup>
    <None Update="Languages\en-US\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Languages\zh-Hans\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Languages\zh-Hant\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="$(AssemblyName)_Config.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="PowerShell.exe -ExecutionPolicy RemoteSigned -Command &quot;&amp;'$(ProjectDir)PostBuild.ps1' '$(TargetDir)' '$(ProjectPath)' '$(AssemblyName)'&quot;" />
  </Target>

</Project>

4. 如图所示更改工程文件【HAPTICCAL.csproj】，重点：TargetFramework改成TargetFrameworks

5. 新的工程文件【HAPTICCAL.csproj】

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

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFrameworks>net480</TargetFrameworks>
    <UseWPF>true</UseWPF>
    <RootNamespace>FirstSolver</RootNamespace>
    <ApplicationIcon>$(AssemblyName).ico</ApplicationIcon>
    <ProduceReferenceAssembly>False</ProduceReferenceAssembly>
    <Authors>秦建辉</Authors>
    <AssemblyVersion>4.3.0</AssemblyVersion>
    <FileVersion>$(AssemblyVersion)</FileVersion>
    <NeutralLanguage>zh-Hans</NeutralLanguage>
    <StartupObject>FirstSolver.Program</StartupObject>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="C2VColorEdit" Version="3.0.0" />
    <PackageReference Include="C2VLanguage" Version="3.0.0" />
    <PackageReference Include="HPSocket.Net" Version="5.9.3.1" />
    <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
    <PackageReference Include="NLogHelper" Version="3.0.0" />
    <PackageReference Include="NLogViewer" Version="3.0.0" />
    <PackageReference Include="TF_Communication_CS" Version="3.0.4" />
  </ItemGroup>

  <ItemGroup>
    <Resource Include="..\TF.png" Link="TF.png" />
    <Resource Include="$(AssemblyName).ico" />
  </ItemGroup>

  <ItemGroup>
    <None Update="Languages\en-US\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Languages\zh-Hans\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Languages\zh-Hant\$(AssemblyName).json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="$(AssemblyName)_Config.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="PowerShell.exe -ExecutionPolicy RemoteSigned -Command &quot;&amp;'$(ProjectDir)PostBuild.ps1' '$(TargetDir)' '$(ProjectPath)' '$(AssemblyName)'&quot;" />
  </Target>

</Project>

6. 出现异常，然后【卸载项目】，再【重新加载项目】。
7. 面向未来升级到.NET 8.0只需要修改"net480"，将"net480"改为"net8.0-windows"即可。
