DynamicMSBuilder

The DynamicVars project contains a custom MSBuild task, UpdateAssemblyInfoTask, which updates the AssemblyInfo.cs file of a .NET project. The task generates new GUIDs and random strings for various assembly attributes, ensuring that each build of the project has unique metadata.

It is essentially a Dynamic MSBuild task to help with minor obfuscation of C# Binaries to evade static signatures on each compilation.

Features

• Update GUID: Generates a new GUID for the assembly.
• Update Assembly Attributes: Randomize values for AssemblyTitle, AssemblyDescription, AssemblyCompany, and AssemblyProduct.
• Update Copyright Year: Randomize the year in the copyright statement.

How To Use and Build

Add the Task to Your Project

• Ensure the DynmaicVars project is built and the DLL is accessible.
• Reference this DLL in your project.

Modify Your Project File (.csproj)

• Open your .csproj file in a text editor.
• Compile DynmaicVars.cs to a Class Library, then include the DLL in the csproj to help with compilation, add it at the end just before the </project> tag:

<Project Sdk="Microsoft.NET.Sdk">

  <!-- rest of .csproj file -->

  <UsingTask TaskName="UpdateAssemblyInfoTask" AssemblyFile="$(OutputPath)DynmaicVars.dll"/>

  <Target Name="BeforeBuild">
    <UpdateAssemblyInfoTask FileToUpdate="Properties/AssemblyInfo.cs"/>
  </Target>

</Project>

Build Your Project

• When you build your project, the BeforeBuild target triggers the UpdateAssemblyInfoTask, updating the AssemblyInfo.cs file.
• In Visual Studio locate the Solution Explorer, right click on "References" and select "Add Reference". You'll need the following:
  • Microsoft.Build.Framework
  • Microsoft.Build.Utilities
