You have to load the PDB before modifying the assembly and save it to
disc with the assembly after modifying. The code should look something
like this:
AssemblyDefinition cecilAssembly =
AssemblyFactory.GetAssembly(assemblyName);
cecilAssembly.MainModule.LoadSymbols(); // this involves Cecil.Pdb.dll
or Cecil.Mdb.dll, base on what system you'r running it
// modify the assembly
cecilAssembly.MainModule.SaveSymbols();
AssemblyFactory.SaveAssembly(cecilAssembly, assemblyName);
Or at least it works for me like that. I've had some problems with
writing to the files becaue they're locked, though...
The code looks a bit strange as you don't have a direct reference to
Cecil.Pdb.dll or Cecil.Mdb.dll: they are loaded dynamically by Cecil.dll
based on the current system (MS.NET/Mono) to have portable code. The two
assemblies must be put at a place where they can be found by the .NET
runtime.
