orchardcms - 重新初始化 Orchard Core 数据库

问题描述

到目前为止，为了重新初始化 Orchard CMS，我删除了导致 Orchard 显示设置页面的 app_data/Site 文件夹。由于某种原因，这不再起作用，我收到以下错误

System.NullReferenceException: Object reference not set to an instance of an object.

如果我只是删除 settings.txt 文件，也会发生这种情况

我的问题是强制果园显示设置页面的最佳方法是什么。我正在运行 1.0.0-beta3-70136

解决方案

该错误是由我注入 Orchard ISiteService 类引起的。不知道为什么，但我删除了 DI 并且错误消失了
