In SQL Server 2014, you can compile the tables and stored procedures to native code. This concept is called Native Compilation.
Native Compilation:
Native Compilation is a new concept introduced in SQL Server 2014. Native compilation allows the tables and the stored procedures accessing them to be loaded on the memory. The tables and stored procedures loaded on the memory tends to be faster than the regular tables and stored procedures. The output of native compilation is DLL. These dlls are loaded to the SQL Server Process.
This dll creation process happens during the creation of memory optimized tables and memory optimized stored procedures. So there is no additional step for creating the dlls. This will be handled during the memory optimized object creation.
These memory optimized objects are re-compiled to dll, every time the sql server restarts.
Native Compilation of Tables:
The table is natively compiled when they are created using the table option memory_optimized=on. This option is used for creating the table optimized for In-Memory OLTP. On executing the create table script, the SQL Server Engine, compiles the script to native code and outputs a dll file. This dll file will be loaded to the memory for faster data access. For creating a memory optimized table, read the article Creating Table Optimized for In-Memory OLTP.
This resulting native compiled dll files are not stored in the database. Instead they are stored in the physical file system in the hard disk. You can see the location of the files using the dynamic management view dm_os_loaded_modules.

This dmv gives you the location of the files created for the memory optimized table, including the native compiled dll. If you go to the folder you can see several files with the same object id. One of the file will be “C” native code file and another is the resultant dll.
If you open the file with c extension, you can see the code written in c, so as to be compiled to a dll. Below is the sample c code. The table creation script is converted to c code and then compiled to a dll file. The natively compiled files for the table starts with the extension xtp_t_.

Native Compilation of Stored procedures:
The stored procedure is natively compiled when they are created using the option NATIVE_COMPILATION. This option is used for creating the stored procedure optimized for In-Memory OLTP. On executing the create procedure script, the SQL Server Engine, compiles the script to native code and outputs a dll file. This dll file will be loaded to the memory for faster data access. For creating memory optimized stored procedure, read the article Natively Compiled Stored Procedure.
Just like the memory native compilation of tables, the resulting native compiled dll files for stored procedures are stored in the physical file system in the hard disk. You can see them in the same folder where you saw the compiled files for tables. You can also see the location of the files using the dynamic management view dm_os_loaded_modules.

Below is the sample c code created during the compilation of stored procedure. Just like the memory optimized tables the memory optimized stored procedure creation script is converted to c code and then compiled to a dll file. The natively compiled files for the table starts with the extension xtp_p_.
