一、EF Core8  数据库连接字符串报错

A connection was successfully established with the server, but then an error occurred during

解决方案：

连接字符串增加标识

TrustServerCertificate=True

或者加（Encrypt=True;TrustServerCertificate=True;）即可：

"ConnectionStrings": {

"DefaultConnection": "Data Source=LAPTOP;Initial Catalog=DB;persist security info=True;User ID=sa;Pwd=XXXXX;Encrypt=True;TrustServerCertificate=True;"

},

字符串格式2：

 "SqlServer": "data source=xxx;initial catalog=QL.Back.Template6;uid=xxx;pwd=xxxx;TrustServerCertificate=True;"
