Does anyone know how could I check if the email and password from EditForm exists in database? I'm using Blazor Server and SQL Server as database and I already have the models from database and the context. I know I should do a service class for user and then call it in the Login page, but I'm not sure how. Thanks!

If so, I think this document may help you, you can use
OnValidSubmithere to write your code.
