Keep in mind, handling errors is a vast design subject.

i recommend reading the official documentation first.  It you still have question after reading the documentation then share those questions here and explain exactly what you are trying to do.

if the error happens in database then you need to use RAISEERROR IN sql Server to pass that error to ASP.NET Core

If an error occurred in some library and need to pass this to UI, you can use Throw an exception

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/exceptions/creating-and-throwing-exceptions

You can use Try catch block with code specific errors and handle error exception

For handling all unhandled exceptions globally you can use the Application_Error event in global.asax
