You are developing an e-commerce application and want to handle exceptions such that any database-related exception shows a "Service temporarily unavailable" message to the user. How would you achieve this in ASP.NET Core?

In ASP.NET Core, you can achieve this by using global exception handling middleware. You can create a custom middleware that catches exceptions, checks if they are database-related, and then returns a "Service temporarily unavailable" response to the user. This approach centralizes exception handling and avoids the need for try-catch blocks in every database operation.
