在 Linux 上的 ASP.NET Core MVC 項目中構建身份腳手架后運行項目時出現問題

Question

我試過添加

<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，與錯誤不符。 重建應用程序后錯誤仍然相同。

項目.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>

Startup.cs 的第 36 行：

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

解決了！ 我按照以下順序分別卸載了 dotnet 包：dotnet-sdk-bin (AUR) dotnet-runtime-bin (AUR) dotnet-host-bin (AUR)

然后我以相反的順序構建了這些相同的包。 現在它們都在 3.1.1.sdk101-2 到今天，我的項目再次運行。

Answer 1

我注意到了同樣的事情，請查看框架的 ms 更新，幾天前有一個更新，預計已安裝較新的 nuget 軟件包。

您遇到的問題是 nuget 軟件包與您的 SDk 不匹配，至少我是這樣。 在進行 Windows 更新並安裝新的 Core Runtime 后，Version=3.1.1.0 一切正常

Answer 2

我通過重新安裝解決了這個問題：.Net Core SDK 3.1.101 和 ASP.NET Core Runtime 3.1.1

https://dotnet.microsoft.com/download/dotnet-core/3.1

Answer 3

問題出在 ASP.NET Core 標識包的最新 3.1.1 版本中。 當我恢復到以前的穩定 3.1.0 版本時，它工作正常。 見下面的快照：

對我來說，安裝最新的 SDK 和 Core Runtime 並沒有解決這個問題。
