title: Is there any IL editor to change the bytecode of an assembly?
body: <p>I've detected some defects on legacy third party assemblies that we're using on our code decompilind them. I would like to fix them but as I don't have the source code I need to directly modify the bytecode. The changes are really simple (changing an AND for an OR and NOPing some lines).</p>
  
  <p>Is there an editor to do this kind of things? Doing the work with an hex editor would be the last option, I would preffer to have a hint of what instructions I have around the cursor ...</p>
