c# - 升级到 .net 5 程序集缺少框架版本

Question

我正在将项目升级到 .net 5，但在构建时遇到了最奇怪的错误。

 <ResolvePackageAssets 
  ProjectAssetsFile="$(ProjectAssetsFile)"
  ProjectAssetsCacheFile="$(ProjectAssetsCacheFile)"
  ProjectPath="$(MSBuildProjectFullPath)"
  ProjectLanguage="$(Language)"
  EmitAssetsLogMessages="$(EmitAssetsLogMessages)"
  TargetFramework="$(TargetFramework)"
  RuntimeIdentifier="$(RuntimeIdentifier)"
  PlatformLibraryName="$(MicrosoftNETPlatformLibrary)"
  RuntimeFrameworks="@(RuntimeFramework)"
  IsSelfContained="$(SelfContained)"
  MarkPackageReferencesAsExternallyResolved="$(MarkPackageReferencesAsExternallyResolved)"
  DisablePackageAssetsCache="$(DisablePackageAssetsCache)"
  DisableFrameworkAssemblies="$(DisableLockFileFrameworks)"
  CopyLocalRuntimeTargetAssets="$(CopyLocalRuntimeTargetAssets)"
  DisableTransitiveProjectReferences="$(DisableTransitiveProjectReferences)"
  DisableTransitiveFrameworkReferences="$(DisableTransitiveFrameworkReferences)"
  DotNetAppHostExecutableNameWithoutExtension="$(_DotNetAppHostExecutableNameWithoutExtension)"
  ShimRuntimeIdentifiers="@(_PackAsToolShimRuntimeIdentifiers)"
  EnsureRuntimePackageDependencies="$(EnsureRuntimePackageDependencies)"
  VerifyMatchingImplicitPackageVersion="$(VerifyMatchingImplicitPackageVersion)"
  ExpectedPlatformPackages="@(ExpectedPlatformPackages)"
  SatelliteResourceLanguages="$(SatelliteResourceLanguages)"
  DesignTimeBuild="$(DesignTimeBuild)"
  ContinueOnError="$(ContinueOnError)"
  PackageReferences="@(PackageReference)">

我正在使用 SimplyCommerce 中的包来创建模块化网站，但收到此错误。

Severity    Code    Description Project File    Line    Suppression State
Error   MSB4044 The "ResolvePackageAssets" task was not given a value for the required parameter "TargetFramework". SimplCommerce.Module.PaymentPaypalExpress   C:\Program Files\dotnet\sdk\5.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets    241 

当我查看程序集详细信息时，我已将其重命名为仓库 crm，但当我查看目标框架时，它显示为空白。尽管我之前已经设置过，但 .net 5 是运行最新 Visual Studio 的工具中的一个错误，当我双击该错误时，它会将我带到此文件

C:\Program Files\dotnet\sdk\5.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets

在您询问之前，.net 5 已安装在目标计算机上。

这是有问题的库的 csproj 文件，您将看到它们不是框架版本，因为它是 razor sdk 库

<Project Sdk="Microsoft.NET.Sdk.Razor">
 
  <PropertyGroup>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
  </PropertyGroup>
 
  <ItemGroup>
    <Content Remove="bundleconfig.json" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="bundleconfig.json" />
  </ItemGroup>

  <ItemGroup>
    <Folder Include="Areas\PaymentPaypalExpress\Components\" />
    <Folder Include="Areas\PaymentPaypalExpress\Views\Shared\Components\" />
    <Folder Include="Data\" />
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Warehouse.Infrastructure\Warehouse.Infrastructure\Warehouse.Infrastructure\Warehouse.Infrastructure.csproj" />
  </ItemGroup>

</Project>

Answer 1

在 .csproj 文件中添加目标框架将解决该问题。

对于.NET 5

<PropertyGroup>
        <TargetFramework>net5.0</TargetFramework>
</PropertyGroup>

对于.NET 6

<PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
</PropertyGroup>

所有其他版本，另请参阅MSDN - frameworks
