打破微软封印面向未来创建.NET Framework4.8工程

摘要：

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。
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？
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：

创建新项目，【WPF 应用程序】

选择框架【.NET 8.0（长期支持）】

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>

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

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>
