UMDF 2 driver INF file error: 'The third-party INF does not contain digital signature information'

Question

I'm developing a UMDF 2 driver and having trouble with the INF file. The Microsoft documentation is hard to understand, and I'm getting an error when I try to install my driver.

Here is my INF file:

[Version]
Signature="$Windows NT$"
Class=System
ClassGuid={4d36e97d-e325-11ce-bfc1-08002be10318}
Provider=%ManufacturerName%
CatalogFile=User.cat
DriverVer=06/01/2024,1.0.0.0
PnpLockdown=1

[Manufacturer]
%ManufacturerName% = Standard,NT$ARCH$.10.0...22000

[Standard.NT$ARCH$.10.0...22000]
%DeviceName% = hdigya, Root\User

[SourceDisksFiles]
User.dll=1

[SourceDisksNames]
1 = %DiskName%

; =================== UMDF Device ==================================

[hdigya.NT]
CopyFiles=UMDriverCopy
Include=wudfrd.inf
Needs=WUDFRD.NT

[hdigya.NT.hw]
Include=wudfrd.inf
Needs=WUDFRD.NT.HW

[hdigya.NT.Services]
Include=wudfrd.inf
Needs=WUDFRD.NT.Services

[hdigya.NT.Wdf]
UmdfService=User,User_Install
UmdfServiceOrder=User

[User_Install]
UmdfLibraryVersion=$UMDFVERSION$
ServiceBinary=%13%\User.dll

[DestinationDirs]
UMDriverCopy=13

[UMDriverCopy]
User.dll

; =================== Generic ==================================

[Strings]
ManufacturerName="how-do-i-get-your-attention.com"
DiskName="User Installation Disk"
DeviceName="User Device"

I have run the following commands to disable driver signature enforcement:

bcdedit /set testsigning on 
bcdedit /set nointegritychecks on 
bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

I have also installed the self-signed code signing certificate many times.

However, when I try to install the driver using pnputil, I get the following error:

pnputil /add-driver user.inf /install
Microsoft PnP Utility

Adding driver package:  User.inf
Failed to add driver package: The third-party INF does not contain digital signature information.

Total driver packages:  1
Added driver packages:  0	

I'm confused about what I'm missing. Can anyone help me understand why this error is occurring and how to fix it?

HAPPY CODING.

Sorry, I posted this under Visual Studio but I couldn't find tags for UMDF and C.
