It's a simple web store project with a few products listed and shopping cart added. The web site works, I can see products, details, pictures and add to shopping cart.

这是一个简单的网上商店项目，列出了一些产品和购物车添加。网站工作，我可以看到产品，细节，图片和添加到购物车。

But when I try to add a Razor view of any object of any type (create, edit, list), I get this error:

但是，当我尝试添加任何类型(创建、编辑、列表)的任何对象的Razor视图时，我收到以下错误：

No code generators found with the name 'view'

at Microsoft.VisualStudio.Web.CodeGeneration.CodeGeneratorsLocator.GetCodeGenerator(String codeGeneratorName)

at Microsoft.VisualStudio.Web.CodeGeneration.CodeGenCommand.Execute(String[] args)

Project file has all references correct with correct versions:

项目文件的所有引用都是正确的，版本正确：

I have latest packages installed, uninstalled and reinstalled and still get same error.

我安装、卸载并重新安装了最新的程序包，但仍然出现相同的错误。

Checking available code generators shows that they are all installed:

检查可用的代码生成器显示它们都已安装：

I suspect it could be related to the Microsoft.AspNetCore.Identity.EntityFrameworkCore package, but I'm not sure how to get around it without it, since it's needed for the project.

我怀疑它可能与Microsoft.AspNetCore.Identity.EntityFrameworkCore包有关，但我不确定如何在没有它的情况下绕过它，因为它是项目所需的。

I spent the last 2 days googling, but could not find a solution.

我花了两天时间在谷歌上搜索，但找不到解决方案。

Can someone help?

有人能帮帮忙吗？

Thank you.

谢谢。

trying to create view from terminal i get this error ''' " Could not
load file or assembly 'Microsoft.EntityFrameworkCore,
Version=6.0.21.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

Try to add package Microsoft.EntityFrameworkCore.Design 6.0.21

尝试添加包Microsoft.EntityFrameworkCore.Design 6.0.21

Change the Version to 6.0.21 like below:

将版本更改为6.0.21，如下所示：

 <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="6.0.21">

I ended up creating new project, and building everything from 0.
Installed all latest packages. I think the problem was related to DBcontext declaration, its declaration in program.cs, and connection string in appsettings.json. But still not sure why, because when i tried to fix everything in existing project to match new project - it did not work.. maybe some internal bug.

我最终创建了新项目，并从0开始构建所有内容。已安装所有最新程序包。我认为这个问题与DBContext声明、它在Program.cs中的声明以及appsettings.json中的连接字符串有关。但仍然不确定为什么，因为当我试图修复现有项目中的所有内容以匹配新项目时-它不起作用。可能是内部的缺陷。
