Easy update assistance

We are writing simple architectured software in 开发者_JAVA技巧C# 3.5.

What I was searching for is for easy updating framework/application...

We don't have COM components, Servicdes to install or whatever, so basically what we need is xcopy stuff form one Server side directory to the client. So what the program should do is like a workflow:

1. Check some location \Server\Updates for manifest.xml
2. Check the local setup verison
3. Download all available DLLs (doesn't necessary all need for complete application, so kind of patch stuff) and substitude them with "old" ones.

I'm aware of ClickOnce, of App publishing, also our setup generator supports autoamtic updates (even if noone yet used it, and I don't want to use to not strongly couple ourselfs with that technology).

Do you know some app or technology, that I'm not aware (actually listed in question) which could better fit our needs. ?

Thank you in advance.

So, after the comment, the answer:

I would look at this SO post.

I looked wyWuild and the AutomaticUpdater controler some time ago. It really looked great.

EDIT

I just remembered that I chose to use AppLife Update in the end. It's more expensive but the features are extremely good
