my C# application with .mdf database works fine in my development machine ..
but when I try to run the program an another machine I receive this error message..
an attempt to attach an auto-named database for file <my development machine .mdf path> failed.
a database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
this is my connection String
<add name="conn" connectionString="Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\mr-ho\source\repos\HighTopClinic\HighTopClinic\clincDB.mdf;Integrated Security=True"
I'm using SqL LocalDB 2019
