I'm using an ant based build system, and had a similar question about updating AssemblyInfo.cs.
My build system already generates version.h files that are included into other projects at build time. For C#, I decided to use the generated VersionInfo.cs for version info injection into AssemblyInfo.cs.
AssemblyInfo.cs (setup once specifying the VersionInfo constants)
using System.Reflection;
using System.Runtime.InteropServices;
[assembly: AssemblyCompany(VersionInfo.Company)]
[assembly: AssemblyProduct(VersionInfo.ProductName)]
[assembly: AssemblyCopyright(VersionInfo.Copyright)]
[assembly: Guid("12345678-1234-1234-1234-1234567890ab")]
[assembly: AssemblyVersion(VersionInfo.product.FileVersion)]
[assembly: AssemblyFileVersion(VersionInfo.sdk.FileVersion)]
VersionInfo.cs (dynamically generated by the ant build system)
// Shared Product Version Header
// Automatically Generated: Sat, 2 May 2015 15:09:09 EDT
// ReSharper disable CheckNamespace
// ReSharper disable InconsistentNaming
internal struct VersionInfo
{
public const string Company = @"My Company Corp";
public const string Copyright = @"Copyright (c) 2015 My Company Corp. All rights reserved.";
public const string ProductName = @"My Software Service";
public const string SpecialBuild = @"";
public const string ProductConfiguration = @"";
public const string ProductCode = @"MSS";
public const string ProductUrl = @"www.MyCompany.com";
public const string ProductEmail = @"support@MyCompany.com";
public const string ProductVendor = @"My Company Corp";
internal struct product
{
public const string FileVersion = @"1.5.0.240";
}
internal struct sdk
{
public const string FileVersion = @"1.4.5.222";
}
internal struct service
{
public const string FileVersion = @"1.3.2.142";
}
}
version.xml (ant import - snipped)

version.properties (ant properties file specifying product version info)
product.company=My Company Corp
product.copyright=Copyright (c) 2015 My Company Corp. All rights reserved.
product.website=www.MyCompany.com
product.email=support@MyCompany.com
product.vendor=My Company Corp
product=1.5.0.240
service=1.3.2.142
sdk=1.4.5.222
C# pre-build event (copies auto-generated VersionInfo.cs to project Properties directory)
@ECHO OFF
SETLOCAL
SET ARTDIR=$(ProjectDir)..\..\..\MySoftwareService\installer
SET VERCS=%ARTDIR%\VersionInfo.cs
ECHO Updating %VERCS%
xcopy /D /Y "%VERCS%" "$(ProjectDir)Properties"
MSBuild Extensions (none!)
<!-- none, not required -->
BTW, my version scheme is: major.minor.revision.build which isn't what the AssemblyInfo.cs file specifies.
