Question

I have tried the below

Answer 1

In .Net core 3.0 or above version,Please use below code: Instead of System.Data.SqlClient.SqlParameter Use Microsoft.Data.SqlClient.SqlParameter

 int AuthourId = 3;
 Microsoft.Data.SqlClient.SqlParameter authorId = new Microsoft.Data.SqlClient.SqlParameter("@AuthorId", AuthourId);
 IEnumerable<Book> booksByAuthor = shopDbContext.Books
                                                .FromSqlRaw("Select * from Book where AuthorId=@AuthorId", authorId)
                                                .ToList();

Answer 2

InvalidCastException: The SqlParameterCollection only accepts non-null SqlParameter type objects, not SqlParameter objects.

For the above error, SqlParameter should be Microsoft.Data.SqlClient.SqlParameter not System.Data.SqlClient.SqlParameter
