4.1 Begin with INF file

The following is an example of the INF file of an application named SampleApplication. For UEFI Application, the MODULE_TYPE entry should be UEFI_APPLICATION. The difference compared to Pei/Dxe/Uefi driver is that UEFI_APPLICATON has no dependency relationship section.

[Defines]
  INF_VERSION                = 0x00010005
  BASE_NAME                  = SampleApplication
  FILE_GUID                  = XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
  MODULE_TYPE                = UEFI_APPLICATION
  ENTRY_POINT                = SampleApplicationEntryPoint
  UEFI_SPECIFICATION_VERSION = 0x0002001E

[Sources]
  Sample.c

[Packages]
  MdePkg/MdePkg.dec

[LibraryClasses]
  UefiApplicationEntryPoint
  DebugLib

[protocol]
  gSampleProtocolGuid

[Guids] gSampleGuid

Note: If a module is dependent on the new definitions or features in

EFI_BOOT_SERVICES or UEFI_RUNTIME_SERVICES-defined in UEFI specifications from version 2.1 forward-the hex version needs to be given in INF file [Defines] section's UEFI_SPECFIICATION_VERSION field.
