我刚从.Net Core 1.0升级到.NET Core 1.1 我已经有了使用.Net Core 1.0的项目 我如何成功迁移。 因为我尝试过使用

dotnet migrate

迁移它是成功的，但是当我尝试运行时

dotnet restore

我显示了很长的错误，如下所示

我该怎么办？

是的，我已经解决了 运行后

days == 87.97

运行

else

哦，我差点忘了

编辑webprojectfile.csproj文件

而不是

dotnet migrate

更新文件以反映netcore最新版本 如下图所示

dotnet restore

这是改变这一行

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>
    <DebugType>portable</DebugType>
    <PreserveCompilationContext>true</PreserveCompilationContext>
    <AssemblyName>webproj</AssemblyName>
    <OutputType>Exe</OutputType>
    <PackageId>webproj</PackageId>
    <UserSecretsId>aspnet-WebApplication-0799fe3e-6eaf-4c5f-b40e-7c6bfd5dfa9a</UserSecretsId>
    <RuntimeFrameworkVersion>1.0.4</RuntimeFrameworkVersion>
    <PackageTargetFallback>$(PackageTargetFallback);dotnet5.6;dnxcore50;portable-net45+win8</PackageTargetFallback>
  </PropertyGroup>

  <ItemGroup>
    <None Update="wwwroot\**\*;Views\**\*">
      <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
    </None>
  </ItemGroup>

到

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
    <DebugType>portable</DebugType>
    <PreserveCompilationContext>true</PreserveCompilationContext>
    <AssemblyName>webproj</AssemblyName>
    <OutputType>Exe</OutputType>
    <PackageId>webproj</PackageId>
    <UserSecretsId>aspnet-WebApplication-0799fe3e-6eaf-4c5f-b40e-7c6bfd5dfa9a</UserSecretsId>
    <RuntimeFrameworkVersion>1.1.0</RuntimeFrameworkVersion>
    <PackageTargetFallback>$(PackageTargetFallback);dotnet5.6;dnxcore50;portable-net45+win8</PackageTargetFallback>
  </PropertyGroup>

  <ItemGroup>
    <None Update="wwwroot\**\*;Views\**\*">
      <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
    </None>
  </ItemGroup>

和

<TargetFramework>netcoreapp1.0</TargetFramework>

到

<TargetFramework>netcoreapp1.1</TargetFramework>

编辑：请勿删除或重命名

＆＃34; appsettings.json＆＃34;文件

保留appsettings.json，因为它充当环境文件设置或PHP中的.env。 ：）

同样在Startup.cs文件中

<RuntimeFrameworkVersion>1.0.4</RuntimeFrameworkVersion>

然后你现在可以重新运行以下

<RuntimeFrameworkVersion>1.1.0</RuntimeFrameworkVersion>

然后

if (env.IsDevelopment())
            {
                // comment this line 
                // builder.AddUserSecrets();
                // Use this instead   
               builder.AddUserSecrets("myusersecretAddUserSecrets"); // where myusersecretAddUserSecrets is your secret key or ID 
            }

然后

dotnet restore

您的应用程序应该正常运行现在！希望。 ：）
