Hi I am using WinAppSDK WinUI 3 framework. I created a Service Based-Database and in it I created a table. Now when I run the app I am getting this:
System.Data.SqlClient.SqlException: 'An attempt to attach an auto-named database for file "X" failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.'
Hi @HemanthB-9452,
Any update for this thread? Did the reply(s) could help you? If the response helped, do "Accept Answer". If you have further question, please feel free to let us know.
But in your connection string you use "AttachDbFilename" for a SQL Server User-Instance; not service based DB: it should be "Initial Catalog" or "Database" parameter instead.I created a Service Based-Database
And the error is raised, because the database (file) already exists in SQL Server.
See https://www.connectionstrings.com/sqlconnection/
Hi @HemanthB-9452,
According to your error message, please just to be sure check again your database server as it might already contain a database with the same name. Or please check if the file location of this database is correct.
In addition, please check if the parameters of your connection string is right. Please check below blog to get more.
An attempt to attach an auto-named database for file ....database1.mdf failed
