c# - 在 Linux 上的 ASP.NET Core MVC 项目中使用身份脚手架后运行项目时出现问题

Question

我尝试添加

<PackageReference Include="Microsoft.AspNetCore.Razor.Runtime" Version="2.2.0" />

但是2.2.0是目前可用的最新版本，与错误不匹配。重建应用程序后错误仍然相同。

项目.csproj:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RuntimeIdentifier>linux-x64</RuntimeIdentifier>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.1.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.1" />

    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.1">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>

    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.1" />

    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.1">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>

    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.0" />

    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="3.1.0" />
  </ItemGroup>
</Project>

完整错误:

Startup.cs第36行:

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<AppDbContext>();

解决了!我按以下顺序单独卸载了 dotnet 软件包:dotnet-sdk-bin (AUR)dotnet-运行时-bin (AUR)dotnet-host-bin (AUR)

然后我以相反的顺序构建了这些相同的包。现在，从今天开始，它们都在 3.1.1.sdk101-2，我的项目再次运行。

我也注意到了同样的事情，请查看框架的 ms 更新，几天前有一个更新，预计已安装较新的 nuget 软件包。

您遇到的问题是 nuget 软件包与您的 SDK 不匹配，至少我是这样。在进行 Windows 更新并安装新的 Core Runtime 后，Version=3.1.1.0 一切正常
