Earlier debugging / more detailed dependency error info.

[Ben Harper]

I'm trying to load an assembly of mine from a C# webforms page, but IIS
fails to load the page because of failed dependencies. My problem is that I
cannot for the life of me discover the dependency that is causing the
failure. I have verified that the assembly in question is loadable by a
small test EXE. Is there any way that I can debug the process at an earlier
stage, or retrieve more helpful error information that simple "The assembly
could not be loaded..."? Any help would be appreciated.. I'm really at a
dead end here.

Thanks,
Ben

Look at dependencies for the assembly in question and not the assembly
itself. Also, look at the permissions on the ASP.NET temporary directory.
Make sure that IUSR (WIndows XP -) or Network Service (Windows 2003) has
access.

A Visual Studio command prompt run of

aspnet_regiis /i

may help, but check perms as well.

Thanks. I've checked what you mentioned, but to no avail. Like I said- a
standalone app which uses the assembly runs fine. It's very odd-- if I
create a mixed-mode dll with a custom entry point, then I get the same
thing. That same mixed-mode dll with the default entry point works ok.
