[英]How do you solve the error “could not load file or assembly 'microsoft aspnetcore razor runtime 3.1 1”,
I've posted this question before but being new I wanted to learn how to write a "proper" question (in case you've tried to help me and I didn't get back immediately, wanted to get it mostly right if not all hopefully I've got the hang of it)我之前已经发布过这个问题,但是作为新手,我想学习如何写一个“正确”的问题(以防你试图帮助我而我没有立即回复,如果不是全部的话,我想把它做对希望我已经掌握了窍门)
This is just registration/login code whose purpose is self explanatory, the error am getting (could not load file or assembly 'microsoft aspnetcore razor runtime 3.1 1) happens in a service registration class in the AddControllers() method, I've tried adding the package specified in the error but it didn't work, I tried a few other similar packages but the result has been the same, when I build I get no errors or warnings but when the app runs I get the error, hope this is enough data to work with.这只是注册/登录代码,其目的是不言自明的,出现错误(无法加载文件或程序集 'microsoft aspnetcore razor 运行时 3.1 1)发生在 AddControllers() 方法中的服务注册 class 中,我尝试添加错误中指定的 package 但它不起作用,我尝试了其他一些类似的包但结果相同,当我构建时我没有收到错误或警告但是当应用程序运行时我收到错误,希望这是足够的数据来处理。

Ciao, I tried to search Microsoft.AspNetCore.Razor.Runtime v. 3.1.1
on NuGet but I found only 2.2.0. Ciao,我试图在 NuGet 上搜索Microsoft.AspNetCore.Razor.Runtime v. 3.1.1
但我只找到了 2.2.0。 I didn't found any reference to 3.1.1.我没有找到对 3.1.1 的任何引用。 Anyway, downgrading Microsoft.AspNetCore.Identity.UI to 3.1.0
should solve your problem as mentioned here无论如何,将Microsoft.AspNetCore.Identity.UI to 3.1.0
应该可以解决这里提到的问题
