umbraco 安装期间无法连接到数据库

Question

我有一个干净的项目，我正在尝试开始。我还创建了一个干净的数据库。

两者都运行在我的电脑上。

我可以使用 linqpad 连接到我的数据库，没有任何问题。但是当我尝试 "customize" 并设置微软 SQL 服务器时，它显示

Could not connect to database

在控制台中，我收到 500 内部服务器错误，时间：

:62164/install/api/PostValidateDatabaseConnection

我能做什么？

编辑尝试使用自定义连接字符串时，我得到了这个：

如果即使使用自定义连接字符串，您仍然收到 500 错误，我认为您的安装有问题，您应该尝试从头开始重新安装 Umbraco
