Microsoft.Security.CodeIntegrity

Microsoft.Security.CodeIntegrity provides APIs for reading, validating, and converting Windows App Control for Business policy data. The package targets .NET Framework 4.6.2, .NET 8, and .NET 9.

Breaking change in version 3

Version 3.0.0 moved the ConfigCI implementation from the inbox Microsoft.ConfigCI.Commands.dll assembly into this package. Types previously exposed from the Microsoft.SecureBoot.UserConfig namespace now use Microsoft.Security.CodeIntegrity or Microsoft.Security.CodeIntegrity.ConfigCi. Please check MIGRATION.md for more info.

This affects compiled applications and PowerShell scripts that explicitly reference the old CLR type names. PowerShell scripts that invoke ConfigCI cmdlets without explicitly naming their implementation types are generally unaffected.

Common replacements:

Old type New type
Microsoft.SecureBoot.UserConfig.Rule Microsoft.Security.CodeIntegrity.ConfigCi.Rule
Microsoft.SecureBoot.UserConfig.DriverFile Microsoft.Security.CodeIntegrity.ConfigCi.DriverFile
Microsoft.SecureBoot.UserConfig.Eku Microsoft.Security.CodeIntegrity.ConfigCi.Eku
Microsoft.SecureBoot.UserConfig.CIPolicyException Microsoft.Security.CodeIntegrity.CIPolicyException
global::SiPolicy Microsoft.Security.CodeIntegrity.SiPolicy

The old DriverFile(AppxPackage) constructor is not available. Use DriverFile(packageFamilyName, packageVersion) or the New-CIPolicyRule -Package PowerShell parameter.

The package also contains MIGRATION.md with the complete migration guidance.

Package usage

<PackageReference Include="Microsoft.Security.CodeIntegrity" Version="3.1.4" />

Example:

using Microsoft.Security.CodeIntegrity;
using System.IO;

using FileStream xmlInput = File.OpenRead(xmlPolicyPath);
using var binaryOutput = new MemoryStream();

Policy.ConvertFromCodeIntegrityPolicy(xmlInput, binaryOutput);
File.WriteAllBytes(binaryPolicyPath, binaryOutput.ToArray());

Standalone XML schemas

The package includes these files for schema inspection of the underlying policy XML:

schemas\cipolicy.xsd
schemas\ApplicationManifest.xsd

Build and test

Build the library:

dotnet build Microsoft.Security.CodeIntegrity\Microsoft.Security.CodeIntegrity.csproj -c Release

Run the tests:

dotnet test LibTests\LibTests.csproj -c Release

BREAKING CHANGE introduced in 3.0.0: ConfigCI implementation types moved from
       Microsoft.ConfigCI.Commands.dll and the Microsoft.SecureBoot.UserConfig namespace
       to Microsoft.Security.CodeIntegrity.dll. Rule, DriverFile, Eku, and related types
       are now under Microsoft.Security.CodeIntegrity.ConfigCi. CIPolicyException is under
       Microsoft.Security.CodeIntegrity. No CLR type-forwarding compatibility layer is provided.
       PowerShell scripts that invoke ConfigCI cmdlets without explicitly naming CLR types are
       generally unaffected. See MIGRATION.md in the package for migration guidance.
