"Error reading key file" when compiling VS.NET web app

[CRogers]

Follow-up: The <Assembly: AssemblyKeyFile("...")> property in my AssemblyInfo.vb file had been using a relative pathname to the key file. I just discovered that if I use an absolute pathname, the build can handle it. However, this isn't an ideal solution, as it removes some amount of location-independence from my project.
