.NET Forum / .NET Framework / CLR / November 2005.NET Assemblies versions
What happens when on a .NET 2.0 application you reference a third party assembly that itself references the 1.0 versions of the .NET CL? (e.g. mscorlib 1.0, System.dll 1.0, etc.). Does the CLR automatically rebind those references to point to the 2.0 versions? I've tested this on a machine that doesn't have the 1.0 nor 1.1 versions installed and the application runs fine. Thanks, Juan >Does the CLR automatically rebind those references to point to the 2.0 >versions? Yes. Search for "assembly unification" in the docs for more details.

Reading the docs (http://msdn2.microsoft.com/en-us/library/db7849ey ) I see a note that states: "Version 1.0 .NET Framework assemblies are not unified. The only way to instruct the runtime to use a .NET Framework assembly that is not version 1.0 is to create a configuration file that contains the appliesTo attribute in the <assemblyBinding> element.", which I interpret to mean that assemblies compiled for .NET 1.0 do not get this treatment. So I'm guessing the referring assembly (the one that has a reference to an 1.0 assembly) needs to be compiled on 1.1 and up so it can be unified? And my main concern: supposing an assembly that has references to 1.0 .NET assemblies is unified to use the 2.0 framework assemblies, would this hurt performance in any way? I mean runtime performance, since I expect there's gonna be a slight performance hit at load time (I guess FUSION does the unification).
