Assembly loading

[Kjetil Kristoffer Solberg]

I have a question regarding assembly loading.Basically I am asking whether
or not the
assembly loader can load multiple versions of the same assembly if:

1. The assemblies are strongly named and lies in the GAC

2. The assemblies are strongly named and lies outside the GAC

3. The assemblies are not signed and loaded using the Load method with a
partial qualified reference(incomplete four-part name).

4. The assemblies are not signed and loaded using the Load method with a
fully qualified reference(complete four-part name).

If it can load multiple versions of the same assembly how does the CLR
differ between types in one version of the assembly
and types in another version? Also this question applies to both statically
bound assemblies as dynamically bound assemblies.

4. The assemblies are not signed and loaded using the Load method with a

I believe the answer is yes for 1 and 2, and no for 3 and 4. But I
suggest you test it yourself to verify.

If it can load multiple versions of the same assembly how does the CLR
differ between types in one version of the assembly
and types in another version?

Type identity is scoped by the full assembly name. So type Foo in
assembly Bar v1.0 is different from Foo in Bar v2.0.
