Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

In this post I will show you how to solved the Issue. Here I am using VS Code.
Previously I had shown

• The entity type '' requires a primary key to be defined.

To solve this problem I had generated certificates as described in the error message as shown below.
    To generate a developer certificate run 'dotnet dev-certs https'.
    To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'.
    But no use.

Don't worry there is a solution.

Steps for solution:

Close all browsers, so that they do not cache the certificate because that will cause other issues.
In the command line run

dotnet dev-certs https --clean

Now to trust the Certificates run below command in the Command Prompt

dotnet dev-certs https -t

Now You can then check the certificate with below Command.

dotnet dev-certs https --check

Now run the project. Problem solved.
