NET Core 2.1開始Identity UI被包進Razor Class Library

NET Core 2.1開始Identity UI被包進Razor Class Library

如果需要Identity Core的cshtml修改可以參考

https://stackoverflow.com/questions/50802781/where-are-the-login-and-register-pages-in-an-aspnet-core-scaffolded-app

指令產生

https://docs.microsoft.com/zh-tw/aspnet/core/fundamentals/tools/dotnet-aspnet-codegenerator?view=aspnetcore-3.1 

先安裝ASP.NET Core scaffolding engine

指令dotnet tool install -g dotnet-aspnet-codegenerator

https://devblogs.microsoft.com/aspnet/aspnetcore-2-1-identity-ui/ 

指令dotnet aspnet-codegenerator identity 

需要先用NuGet安裝以下套件(用Visual Studio的Scaffolding Item會自動安裝)

Microsoft.VisualStudio.Web.CodeGeneration.Design 

Microsoft.AspNetCore.Identity.UI

Microsoft.EntityFrameworkCore.Design

Microsoft.EntityFrameworkCore.SqlServer

error CS0234: 命名空間 'Microsoft.AspNetCore.Identity' 中沒有類型或命名空間名稱 'UI' (是否遺漏了組件參考?)

因為Microsoft.AspNetCore.Identity.UI 3.1.4 只支援.NET Core 3.1以上
https://www.nuget.org/packages/Microsoft.AspNetCore.Identity.UI
所以要把專案升級到.NET Core 3.1以上


obj\Debug\netcoreapp3.0\SkillTreeRazorPageBlogSample.AssemblyInfo.cs(14,42): error CS0234: 命名空間 'Microsoft.AspNetCore.Identity' 中沒有類型或命名空間名稱 'UI' (是否遺漏了組件參考?) [D:\temptest\SkillTreeRazorPageBlogSample.csproj]

TagMode.StartTagAndEndTag

https://docs.microsoft.com/zh-tw/aspnet/core/mvc/views/tag-helpers/authoring?view=aspnetcore-3.1

You can use the following markup with a closing tag and remove the line with TagMode.StartTagAndEndTag in the tag helper:

<website-information info="webContext" >
</website-information>




https://whosnailaspnetcoredocs.readthedocs.io/ko/latest/mvc/views/tag-helpers/authoring.html

[HtmlTargetElement("email", TagStructure = TagStructure.WithoutEndTag)] 
public class EmailVoidTagHelper : TagHelper
{
    private const string EmailDomain = "contoso.com";
    // Code removed for brevity

InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Mvc.Infrastructure.IActionContextAccessor' while attempting to activate

 寫.NET Core遇到Unable to resolve service for type通常是忘記註冊物件給DI容器

 Startup.cs的ConfigureServices(IServiceCollection services)加入以下這一行
            //TagsHelper使用
            services.AddSingleton<IActionContextAccessor, ActionContextAccessor>();


錯誤訊息:
InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Mvc.Infrastructure.IActionContextAccessor' while attempting to activate

IList和IEnumerable的比較

自己通常使用IEnumerable<T>
但還是會有需要用到IList<T>的時候
