As I am not able to write any code i

Answer 1

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)

// Shared Product Version Header${line.separator}
// Automatically Generated: ${version.generated.time}${line.separator}
// ReSharper disable CheckNamespace${line.separator}
// ReSharper disable InconsistentNaming${line.separator}
internal struct VersionInfo${line.separator}
{${line.separator}
  public const string Company = @"${product.company}";${line.separator}
  public const string Copyright = @"${product.copyright}";${line.separator}
 
}${line.separator}

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!)

BTW, my version scheme is: major.minor.revision.build which isn't what the AssemblyInfo.cs file specifies.
