An assembly with the same simple name

[Matthieu GD]

Hello,

I got this exception sometimes (and since a few days only) when I
debug my application. If I rebuild, the exception goes away :

Spark.Compiler.CompilerException was unhandled by user code
Message="Dynamic view compilation failed.:
error CS1704: An assembly with the same simple name 'XXX.Web,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null has already been
imported. Try removing one of the references or sign them to enable
side-by-side

It's the assembly of my web project but it can be another assembly
from a project I just modified. I see the post about the same problem
when using NUnit Console but here I don't use any extermal programm.
