I actually did. Cecil 0.6 has a ConstructorParameters collection that was renamed in 0.9, hence the confusion. CustomAttribute.Constructor.Parameters actually point to the parameters of the constructors. You don't want to modify that unless you want to modify the constructor of say, AttachDataAttribute. > I'm not trying to add a new Attribute, I'm trying to modify an > existing attribute in the assembly (as per example). The principle is the same, instead of creating a new one, you can just modify an existing one. You can add a CustomAttributeNamedArgument in the Properties, and if everything is correct, it will be serialized at Write time. > Further to previous question, I get the type by resolving the > module.TypeSystem.CorLib to an AssemblyDefinition and using GetType on > the MainModule, this guarantees I get the type from the right > framework library and avoid creating a dependency on the Type in the > framework currently being used.

It shouldn't be a problem to modify an existing one. Jb -- -- mono-cecil
