 May be i am wrong but i think that you do not need to Download the assembly with a downloader before loading it with Assembly.Load. Well, when i noticed that the assembly must be in the project folder, i had some doubt that the loader is getting the assembly directly from the project directory and not because it was downloaded. I tried to test that in a new project where i putted my DLL in the project directory then i tried to load it directly with Assembly.Load and i added it to the main Canvas and this work fine.

I'm affraid that what i said is wrong because in all the article and codes (including Pete and Damoxc codes) i found that the loading is done after downloading the DLL, so could you check out please.

I'm not quite sure I understand what you're saying.

If you mean that an assembly can be downloaded and used without using the downloader object, I assume in that instance, you had a reference to it at compile time and/or you didn't clear your browser cache. If not, I will test this in my own code and see what happens, however I don't believe anything useful happens without using the downloader to first snag the DLL.
