我正在开发.net核心Web应用程序.我在同一解决方案中有两个Web应用程序.我将appsettins文件从正在运行的Web应用程序移至出现问题的应用程序，情况仍然相同.无法找出我所缺少的东西

推荐答案

我遇到了同样的问题.就我而言，我将开始实施应用程序的机密，但半途而废.我的 secrets.json 文件被保留链接，但使用无效的JSON.

I came across the same problem. In my case, I'd started implementing app secrets but left it halfway through. My secrets.json file was left linked but with invalid JSON.

检查您的 .csproj 以查看是否在< PropertyGroup> 下设置了< UserSecretId> 属性.如果已设置，则 BuildWebHost()将浏览'％APPDATA％\ Microsoft \ UserSecrets \ {secretId}'中的 secrets.json 文件，以及您的 appsettings.json 文件.任何一个文件中的错误都会导致该方法失败，但不会告诉您该文件是哪个文件.

Check your .csproj to see if a <UserSecretId> property is set under <PropertyGroup>. If it's set, BuildWebHost() will look through your secrets.json file in '%APPDATA%\Microsoft\UserSecrets\{secretId}', in addition to your appsettings.json file. An error in either file will cause the method to fail, but it won't tell you which file it is.

我的解决方案是删除< UserSecretId> 属性或

The solutions in my case were either to remove the <UserSecretId> property or
