Hello, I am reading the documentation suggested and it isn't required to run under profiler since you can read and add new MetaData elements starting from an instance of IMetaDataDispenser.
Thanks, Pierre
This is a very bad solution under most circumstances - NORMALLY you would want your program not to run under the profiler. I face similar limitations in other situations (the need to replace a method's bytecode at load time), and I found having the profiler running during program run not to be acceptable.

You can write an unmanaged profiler that adds the attribute at load time. Have a look at Profiling.doc and Metadata Unmanaged.doc/Assembly Metadata Unmanaged.doc in your FrameworkSDK\Tool Developers Guide\Docs folder.
You will have to: Write a COM component implementing ICorProfilerCallback Intercept the ModuleLoadFinished or ClassLoadFinished events Get the IMetaDataAssemblyEmit and IMetaDataEmit interfaces for the module you want to manipulate Add a MemberRef to the attribute's constructor (and probably an AssemblyRef and TypeRef as well) Finally add the custom attribute
This is just a rough outline, so be sure to read the documents I mentioned.

Hello, I have an assembly containing a Type and I need to add an attribute to a method of that type at run-time. I tryied to look inside System.Reflection.Emit but I didn't found the way of adding the custom attribute of an already created type.
Someone suggested that there are some unmanaged APIs to do that but I didn't found any document talking about them.
Thanks for any help, Pierre
