Can you please provide a link to the learning project you were following along?
Also provide information about the basic setup you have. Is the connection string to the database correct, are all the pre-requisites installed and available?

Side note: please keep in mind that this repo here is for development of ASP.NET Core, so you may get better advices / help when asking questions like this one on https://stackoverflow.com/ and similar sites.

Sorry that i didn't make it clear. here's the link of the project i am following "https://learn.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?source=recommendations&view=aspnetcore-7.0&tabs=visual-studio ".
it seems that i forgot to use Entity Framework Core to deal with the database.
thank you for answering my question. It's so kind of you. I'll take your advice to ask questions on stackoverflow.
By the way. SIr, i'm wondering if you could give me some advice about learning C# in developing website.
may you have a good day

I'm glad you could solve that problem.

give me some advice about learning C# in developing website.

In regards to learning it depends on you learning style. Some people prefer the docs, others blogs, and others watching videos.
For docs a good starting point is Tutorial: Get started with ASP.NET Core.
So depending on your learning style try searching for "ASP.NET Core" maybe together with "tutorial", "basics", etc. I'm pretty sure you'll find enough information to get started. Good luck and enjoy your journey with ASP.NET Core.

I'm really appreciate with your advice sir. I started this project with google "how to build a website with C#". So actually i have no ideal on where to start.
About the learning material, both docs and videos are suitablt for me. Now i'll start my learning from the docs.
Wish you good luck Sir
and with my best regards.
