Hello Manikandan,

Answer to your first question : Yes,

Please follow below steps,

Step-1: Install Entity Framework Core Tools:

dotnet tool install --global dotnet-ef

Step-2: Install EF Core Design Package:

dotnet add package Microsoft.EntityFrameworkCore.Design

Step-3: Create a Database Context: If you have existing then verify with this one

public class YourDbContext : DbContext
{
    public YourDbContext(DbContextOptions options)
        : base(options)
    {
    }

    // DbSet properties for your entities
}

Step-4: Scaffold the Stored Procedure:

dotnet ef dbcontext scaffold "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer -o Models -t YourStoredProcedureName

Step-5: Use the Stored Procedure in Code:

var result = dbContext.YourStoredProcedureName(parameter1, parameter2);

Hope this will clear your both questions.

Hello,

Yes, it is possible to scaffold existing stored procedures in Entity Framework Core 6 using the Database First approach. Here are the steps to scaffold a stored procedure:
1. Open the command prompt or terminal and navigate to the project directory.
2. Run the following command to scaffold the stored procedure:
```
dotnet ef dbcontext scaffold "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer --context-dir Context --context YourDbContext --no-onconfiguring --no-pluralize --no-views --no-functions --no-stored-procedures --stored-procedures
```
Replace "YourConnectionString" with the connection string to your database and "YourDbContext" with the name of your DbContext class.

This command will scaffold all the stored procedures in your database and generate the necessary code in the specified DbContext class.

To scaffold only specific tables and stored procedures, you can modify the command as follows:
```
dotnet ef dbcontext scaffold "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer --context-dir Context --context YourDbContext --no-onconfiguring --no-pluralize --no-views --no-functions --no-stored-procedures --tables Table1 Table2 --stored-procedures StoredProcedure1 StoredProcedure2
```
Replace "Table1", "Table2", "StoredProcedure1", and "StoredProcedure2" with the names of the specific tables and stored procedures you want to scaffold.

By specifying the tables and stored procedures in the command, only those entities will be scaffolded in the generated code.
