IdentityServer4和ASP.NET Core 2.0

Question

我必须错过一些东西，但我看不到它。
我创建了一个新的“空” ASP.NET 2.0的核心项目
我加入EF核2.0和EF核2.0身份
然后我尝试添加IdentityServer4 2.0 RC1和我得到一个包以下错误消息恢复失败：发生在还原的NuGet包

错误：序列中含有较多的 超过一个匹配元素

有一个在这个项目中没有代码，所以我完全糊涂了。

这里是的csproj文件：

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

    <PropertyGroup> 
    <TargetFramework>netcoreapp2.0</TargetFramework> 
    </PropertyGroup> 

    <ItemGroup> 
    <Folder Include="wwwroot\" /> 
    </ItemGroup> 

    <ItemGroup> 
    <PackageReference Include="IdentityServer4" Version="2.0.0-rc1-update1" />

    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" /> 
    </ItemGroup> 
</Project> 

下面是从包管理器控制台我到NuGet.org电话：

Answer 1

以下是您将项目迁移到asp.net core 2.0的一些更改。 步骤1： 从以下链接下载适用于visual studio 2017的asp.net核心2.0 gx64x。 https://www.microsoft.com/net/download/core 第2步：从包装的NuGet或包管理器控制台 1 - 安装 - 包IdentityServer4 -Version 2.0.0 2，安装，包装IdentityServer4.AspNetIdentity -Version 2.0.0-RC1-UPDATE2

步骤 下载3： 在Csproj文件中更新一些代码。 之前： netcoreapp1.1 后： netcoreapp2.0

Before: 
<PackageReference Include="Microsoft.AspNetCore.Authentication.Cookies" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.2" /> 
<PackageReference Include="Microsoft.AspNetCore.Server.IISIntegration" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="1.1.1" /> 
<PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.1" /> 
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" /> 
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer.Design" Version="1.1.1" /> 
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0" /> 
<PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Configuration.UserSecrets" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Logging" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Logging.Console" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.1" /> 
<PackageReference Include="Microsoft.Extensions.Options.ConfigurationExtensions" Version="1.1.1" /> 
<PackageReference Include="Microsoft.VisualStudio.Web.BrowserLink" Version="1.1.0" /> 
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="1.1.0" /> 
After: 
<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" /> 

Before: 
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.0.0" /> 
<DotNetCliToolReference Include="Microsoft.Extensions.SecretManager.Tools" Version="1.0.0" /> 
<DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="1.0.0" /> 
  
After: 
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" /> 
<DotNetCliToolReference Include="Microsoft.Extensions.SecretManager.Tools" Version="2.0.0" /> 
<DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" /> 

步骤4：在Program.cs中类 更新之前： 公共静态无效的主要（字符串[]参数） { 变种宿主= new WebHostBuilder（） .UseKestrel（） .UseContentRoot（Directory.GetCurrentDirectory（）） .UseIISIntegration（） .UseStartup（） .Build（）; 东道主。跑（）; } After： public static void Main（string [] args） { BuildWebHost（args）.Run（）; } 公共静态IWebHost BuildWebHost（串[]参数）=> WebHost.CreateDefaultBuilder（参数） .UseStartup（） .Build（）; 步骤5： 更新在StartUp.cs

services.AddIdentityServer() 
        .AddDeveloperSigningCredential() 
        .AddInMemoryPersistedGrants() 
        .AddInMemoryIdentityResources(Config.GetIdentityResources()) 
        .AddInMemoryApiResources(Config.GetApiResources()) 
        .AddInMemoryClients(Config.GetClients()) 
        .AddAspNetIdentity<ApplicationUser>(); 

     Before: 
     app.UseIdentity(); 
     After: 
     app.UseAuthentication(); 

步骤6：变化管理登录视图模型

Before: 
public IList<AuthenticationDescription> OtherLogins { get; set; } 
  
After: 
public IList<AuthenticationScheme> OtherLogins { get; set; } 

步骤7： 变化管理器控制器

Before: 
var otherLogins = _signInManager 
                  .GetExternalAuthenticationSchemes() 
                  .Where(auth => userLogins 
                                 .All(ul => auth.AuthenticationScheme != ul.LoginProvider)) 
                  .ToList(); 
  
After: 
var otherLogins = (await _signInManager 
                   .GetExternalAuthenticationSchemesAsync()) 
                  .Where(auth => userLogins 
                                 .All(ul => auth.Name != ul.LoginProvider)) 
                  .ToList(); 

步骤8： 更改罪名Login.cshtml文件 之前： var loginP roviders = SignInManager.GetExternalAuthenticationSchemes（）。ToList（）; 之后： var loginProviders =（等待SignInManager.GetExternalAuthenticationSchemesAsync（））。ToList（）;

Before: 
<button type="submit" class="btn btn-default" 
        name="provider" value="@provider.AuthenticationScheme" 
        title="Log in using your @provider.DisplayName account"> 
    @provider.AuthenticationScheme 
</button> 
  
After: 
<button type="submit" class="btn btn-default" 
        name="provider" value="@provider.Name" 
        title="Log in using your @provider.DisplayName account"> 
    @provider.Name 
</button>
