How exactly does a WSP deploy a dll internally

Question

i am facing a problem with deploying dlls with a WSP. After deploying the first version of the dll using a WSP, if I want to change the dll and redeploy after retracting, it is still referring to the old assembly, even though it is no longer there in GAC. Is there any caching feature in Sharepoint that is not very obvious?

Thanks in advance!

Answer 1

If you are deploying to the GAC, you need to make sure that IIS or the application pool is getting reset after you make any change. The DLL definitely gets cached.
