Visual Studio 2022 - Getting 'The operation has timed out' handling When Connecting to Local SQL Server Database
I'm maintaining legacy code that I've searched everywhere and can't find a clear answer..... After trying multiple solutions online, I still can't figure this out. I'm working with a frustrating scenario when trying to connect my C# application to a local SQL Server database using Visual Studio 2022. I've set up the connection string in my `appsettings.json` file like this: ```json { "ConnectionStrings": { "DefaultConnection": "Server=localhost;Database=MyDatabase;Trusted_Connection=True;" } } ``` However, when I attempt to run the application, I get the following exception: ``` System.Data.SqlClient.SqlException: 'The operation has timed out.' ``` I’ve confirmed that SQL Server is running and I can connect to the database using SQL Server Management Studio (SSMS) without any issues. I've also tried the following steps to resolve the question: 1. Verified that the SQL Server instance name is correct and matches the one in the connection string. 2. Changed the connection type to `tcp` by modifying the connection string: ```json "Server=tcp:localhost;Database=MyDatabase;Trusted_Connection=True;" ``` 3. Increased the timeout value in the connection string to 30 seconds: ```json "Server=localhost;Database=MyDatabase;Trusted_Connection=True;Connection Timeout=30;" ``` 4. Checked the SQL Server Configuration Manager to ensure that TCP/IP protocol is enabled. 5. Ensured that the firewall settings on my local machine allow connections to SQL Server. Despite trying all of these steps, I still get the timeout behavior. Is there anything else I could be missing, or any additional configurations I should check? Any help would be greatly appreciated! For context: I'm using C# on macOS. Am I missing something obvious? For context: I'm using C# on Ubuntu. This is part of a larger REST API I'm building.
