Your application fails to connect to the database and tables are missing. I will review your connection string and database migrations. This ensures a stable connection and complete table structure. My approach directly addresses the reported launch failure and data access issues. This covers connection resolution and migration verification. I will promptly communicate any unexpected issues outside this scope. Recently, I restored database functionality for a similar .NET application experiencing migration inconsistencies. The application successfully accessed all required data afterward. Can you confirm the SQL Server instance is accessible and running before we begin?
