CodeDom and ClickOnce not compatible?


M

Mark Evans

Hi Gurus

I have a windows application that is deployed via ClickOnce (No Touch
Deployment). It uses the CodeDom to create an assembly on the fly. The
problem is that this assembly can't find it's referenced assemblies
(IPSTypes.dll in the example below). It works fine when run locally
but fails when run using clickOnce. I was hoping that
"IO.Directory.GetCurrentDirectory()" would return the path to the
dependent assembly but it actually returns the path to the desktop!!
Any help gratefully appreciated.

Hey Mark

If IPSTypes.dll is placed in the same directory as the assembly building the new assembly using the CodeDom, you can use AppDomain.BaseDirectory or Assembly.GetExecutingAssembly().Location
