ResiLab AssemblyPatcher

The AssemblyPatcher is under active development. The aim is to create a tool, which allows easy .NET assembly modification without IL code struggling.

Write a query with some easy macro instructions to target the method or field, which should be replaced, deleted or add a whole new method to an existing type with plain C# which is compiled by Roslyn.

At the moment only an early version of the .NET library exists, which is the core for the later macro tool. At the moment it could help your to weaving .NET assemblys without purchasing expensive tools for this job ;-)

Example

Here we replace the Main method of an assembly with some new code:

var inspector = new AssemblyInspector("HelloWorld.exe");
  
inspector.Method(x => x.FindMethod("HelloWorld.Program", "Main"))
        .Replace("System.Console.WriteLine(\"This is a patched Hello World!\");");
  
inspector.SaveAs("HelloWorld.Patched.exe");

Here we delete a method from an assembly:

var inspector = new AssemblyInspector("HelloWorld.exe");

inspector.Method(x => x.FindMethod("HelloWorld.Program", "GenerateHelloWorld")).Remove();

inspector.SaveAs("HelloWorld.Patched.exe");
