How to build locally

Step 1: Install Tools

winget install --id Microsoft.Powershell --source winget
winget install --id Git.Git --source winget

For using WDK NuGet feed based build additionally:

winget install --id Microsoft.NuGet --source winget

Step 2: Optional: Disable Strong Name Validation

When: This step is only required if you will be using pre-release versions of the WDK.

As per https://learn.microsoft.com/en-us/windows-hardware/drivers/installing-preview-versions-wdk :

Run the following commands from an elevated command prompt to disable strong name validation:

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\StrongName\Verification\*,31bf3856ad364e35 /v TestPublicKey /t REG_SZ /d 00240000048000009400000006020000002400005253413100040000010001003f8c902c8fe7ac83af7401b14c1bd103973b26dfafb2b77eda478a2539b979b56ce47f36336741b4ec52bbc51fecd51ba23810cec47070f3e29a2261a2d1d08e4b2b4b457beaa91460055f78cc89f21cd028377af0cc5e6c04699b6856a1e49d5fad3ef16d3c3d6010f40df0a7d6cc2ee11744b5cfb42e0f19a52b8a29dc31b0 /f

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\StrongName\Verification\*,31bf3856ad364e35 /v TestPublicKey /t REG_SZ /d 00240000048000009400000006020000002400005253413100040000010001003f8c902c8fe7ac83af7401b14c1bd103973b26dfafb2b77eda478a2539b979b56ce47f36336741b4ec52bbc51fecd51ba23810cec47070f3e29a2261a2d1d08e4b2b4b457beaa91460055f78cc89f21cd028377af0cc5e6c04699b6856a1e49d5fad3ef16d3c3d6010f40df0a7d6cc2ee11744b5cfb42e0f19a52b8a29dc31b0 /f

Step 3: Optional: Install Microsoft .NET Framework 4.7.2 Targeting Pack and Microsoft .NET Framework 4.8.1 SDK

When: This step is only required to build sample usb\usbview .

Option A: Install VS Components

Easy: If you will install Visual Studio (see later) you may at that point select to add both of following individual components:

  • .NET Framework 4.7.2 targeting pack
  • .NET Framework 4.8.1 SDK

Option B: Use EWDK

Easy: If you use EWDK, then all necessary prequisites are included.

Option C: Install Developer Pack

Hardest: Install from https://aka.ms/msbuild/developerpacks -> '.NET Framework' -> 'Supported versions' both of following packages:

  • .NET Framework 4.7.2 -> Developer Pack
  • .NET Framework 4.8.1 -> Developer Pack

This will install following Apps:

  • Microsoft .NET Framework 4.7.2 SDK
  • Microsoft .NET Framework 4.7.2 Targeting Pack
  • Microsoft .NET Framework 4.7.2 Targeting Pack (ENU)
  • Microsoft .NET Framework 4.8.1 SDK
  • Microsoft .NET Framework 4.8.1 Targeting Pack
  • Microsoft .NET Framework 4.8.1 Targeting Pack (ENU)

Step 4: Clone Windows Driver Samples and checkout relevant branch

cd "path\to\your\repos"
git clone --recurse-submodules "https://github.com/microsoft/Windows-driver-samples.git"
cd ".\Windows-driver-samples"

If you are planning to use in-market WDK, then you would typically want to use the 'main' branch:

git checkout main

If you are planning to use a WDK Preview or WDK EEAP release, then you would typically want to use the 'develop' branch:

git checkout develop

Step 5: Create a "driver build environment"

To build the Windows Driver Samples you need a "driver build environment". In essence an environment that consist of following prerequisites:

  • Visual Studio Build Tools including tools such as for example cl.exe and link.exe .
  • The Windows Software Development Kit.
  • The Windows Driver Kit.

Option A: Use WDK NuGet Packages

  • See Download the Windows Driver Kit (WDK) for instructions on how to install Visual Studio, but only complete Step 1. You do not need to install the SDK or the WDK.
  • Launch a "Developer Command Prompt for VS 2022".
  • Restore WDK packages from feed :
cd "path\to\your\repos\Windows-driver-samples"
nuget restore -PackagesDirectory ".\packages"
  • When this is done you should have a .\packages folder that looks like example below:
cd "path\to\your\repos\Windows-driver-samples"
dir /b packages
Microsoft.Windows.SDK.CPP.10.0.26000.1
Microsoft.Windows.SDK.CPP.x64.10.0.26000.1
Microsoft.Windows.SDK.CPP.arm64.10.0.26000.1
Microsoft.Windows.WDK.x64.10.0.26000.1
Microsoft.Windows.WDK.arm64.10.0.26000.1

Option B: Use the Windows Driver Kit

  • Here you will install each of above prerequisites one at a time.
  • See Download the Windows Driver Kit (WDK) for instructions on how to install Visual Studio, SDK, and WDK.
  • Launch a "Developer Command Prompt for VS 2022".

Option C: Use an Enterprise WDK

  • You can also simply use the Enterprise WDK (EWDK), a standalone, self-contained command-line environment for building drivers that contains all prerequisites in one combined ISO.
  • See Download the Windows Driver Kit (WDK) for instructions on how to download the EWDK.
  • Mount ISO image
  • Open a terminal
  • .\LaunchBuildEnv

Step 6: Check all samples builds with expected results for all flavors

pwsh
.\Build-AllSamples

Above builds all samples for all configurations and platforms.

You can refine what exact samples to build, what configurations, and platforms to build. build Here are a few examples:

# Get Help:
Get-Help .\Build-AllSamples

# Build all solutions for all flavors with builds running in parallel:
.\Build-AllSamples

# Build with Verbose output (print start and finish of each sample):
.\Build-AllSamples -Verbose

# Build without massive parallism (slow, but good debugging):
.\Build-AllSamples -ThrottleLimit 1

# Build the solutions in the tools folder for all flavors:
.\Build-AllSamples -Samples '^tools.' -Configurations 'Debug','Release' -Platforms 'x64','arm64'

# Build the solutions in the tools folder for only 'Debug|x64':
.\Build-AllSamples -Samples '^tools.' -Configurations 'Debug' -Platforms 'x64'

Example of expected output:

T: Combinations
B: Built
R: Build is running currently
P: Build is pending an available build slot

S: Built and result was 'Succeeded'
E: Built and result was 'Excluded'
U: Built and result was 'Unsupported' (Platform and Configuration combination)
F: Built and result was 'Failed'
O: Built and result was 'Sporadic'

Building all combinations...

7: NuGet - Additional Notes

To restore a specific version of our WDK NuGet packages:

Follow these steps before running "nuget restore" command:

  • Open the .\packages.config file and update the full version (including the branch if required) in all three entries.
  • Open the .\Directory.build.props file and update the version and build of the package with the same values as in previous step.
  • Open .\Build-SampleSet and change the NuGet build number (used by .\exclusions.csv and for determining infverif flags)
  • Now you can run "nuget restore"

A few examples of how to interact with nuget:

# To add an alternative online NuGet source:
nuget sources add -Name "MyNuGetFeed" -Source "https://nugetserver.com/_packaging/feedname/nuget/v3/index.json"

# To add an alternative local NuGet source:
nuget sources add -Name "MyNuGetFeed" -Source "\\path\to\mylocalrepo"

# To remove an alternative NuGet source:
nuget sources remove -Name "MyNuGetFeed"

# To enumerate NuGet locals:
nuget locals all -list

# To clear NuGet locals:
nuget locals all -clear
