I have this Blazor Server Application, I deployed it to Windows 10 Pro. IIS 10 and SQL Express 2019 installed.
Here is my connection string:
"DefaultConnection": "Data Source=ABC\\SQLEXPRESS;Initial Catalog=InventoryManagement;Integrated Security=True",
Here is the error message:
SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL server is configured to allow remote connection(provider: SNI_PN11, error:26 - Error Locating Server/Instance Specified)
