Unable to load DLL 'webengine.dll'

Lewis Moten

Hello. We are having a problem here trying to compile C# applications. Only
one developer has a problem where they attempt to compile the application and
the compiler complains about being out of memory and unable to find a dll -
webengine.dll.

They have tried rebooting, gettling latest, and a few other things. We can
not determine what is at the heart of this problem. They have Visual
Studio.Net 2005 with .Net Framework 2.0 SP1.

The significant event today was that they installed ASP.NET AJAX Extensions
1.0. They had other issues during compilation that crashed the visual studio
environment all together. We removed ajax references from our web application
and the problem changed after they uninstalled the extensions.

The closest thing that I can find to this problem is perhaps
http://support.microsoft.com/kb/947461 with the mention of webengine.dll and
a memory issue. However, we are using the built-in web server for vs.net
rather then IIS. Also, a patch is not supplied.

In addition, we are uncertain why this problem is occuring on only one of
three developers machines with the same configurations. There development
environment is actually taking up a lot less memory then my own and they have
a lot more free space available in both memory and hard drive space.

The current problem results when they compile the solution (or individual
projects). They see the following errors.

I'd probably start with trying to build each project one at a time rather
than the whole solution, it might help locate the problem. Cleaning the
solution wouldn't hurt either just to get all the assemblies cleared out of
their respective bin folders. I can't see AJAX causing this, we had no
problems at all when we upgraded our sites. The stack trace shows that
MSBuild is having problems locating references for your application due to
the machine being out of memory. Check task manager when the problem is
happening to see what's taking up all their resources. Perhaps there's a
virus on the machine that's causing it.

If push comes to shove, just format and rebuild the machine with a fresh
copy of Windows. A little extreme yes, but it always works.

Hi!
Just got similar problem, however not connected with memory. In my case
solution was simple: playing with .NET framework 2.0 Configuration tool I
changed PermissionSet for My_Computer_Zone from 'FullTrust' to 'Everything'.
After this I got the error Unable to load DLL 'webengine.dll' when I tried to
build my web app in VS 2005. Changing the permission back to 'FullTrust'
solved the problem.

Maybe it helps also in your situation...
