Hi Senthil,
For referencing assemblies in GAC you must to have same version of the
assemblies in another folder, so you will reference this assembly, and in
runtime CLR will check GAC and use the same version from GAC if it can find
it.

Hi Daniel,
Thanks for the comments.
Then y we need the concept can GAC.We can just place different versions in
different folders and access it from that specific folder.
To my understanding GAC is a common place where we can place different
verions of DLLs and access the appropriate version when we want.

Hi Senthil,

Basically you are right, but every strongnamed assembly is signed. When you
put that assembly in GAC, runtime checks the assembly and when you latter
use this assembly from GAC this check is not performed, so referencing
assembly from GAC improves performance. The GAC is complex structure of
subfolders in which you can have many files with same name "myassembly.dll"
for example, which protects us from so-called "dllhell" when one software
vendor put "myassembly.dll" in \windows\system32 folder and another vendor
put own "myassembly.dll" in \windows\system32 folder which overwrites first
file and spoil the application from first vendor.

Regards,
Daniel

Hi,

I would say that one way to force the use of a particular version of you
assembly in the gag is to specifeid the version you want to used by
specifying the corresponding redirection entry in application config file
