For a site we have we sometimes (not always) get an error like this after done a deploy with web deploy:

Exception information:

We do not have deployment retail = true as the messages suggest, but we do have the release-mode on it.

Strange. Do you have any code in App_Code folder?

It should be compiled to App_Code.r4nd0mch4r.dll, instead of App_Code.dll ...

Hi,

Did you try to delete the dll? Did it work?

What are settings for your IIS app pool? Start automatically. We came across the same issue time to time. Does not happend after every deploy. Switched to not-auto-start app pool - seems that this may solve the issue. It's not a solution, just a workaround.

I do a IIS reset and that solves the problem but is not fun to do :(

Just ran into this exact same error, and resetting IIS worked for me. Was this a recurring issue for you, or just once?
