COM DLL caching problem

[sanndeb]

Hi guys hope you all are fine :)

I have built a com visible dll in .Net 3.5. As i wanted to call it from classic asp & I registered it in the following way.

gacutil /i COMCallFromASP.dll
 
regasm /tlb COMCallFromASP.dll
 

and my asp code is like

<%
    Dim obj
    Set obj = Server.CreateObject("COMCallFromASP.HelloWorld")
    Dim str
    obj.SayHello "San", str 
    response.write str 
%>
 

My output is simply "Hello San"

Now I made a change in the function body (not in the parameter or return type) to return like "Hi there San" & the I re-registered the dll by Uninstalling & installing the dll again...

regasm /u COMCallFromASP.dll
gacutil /f /u COMCallFromASP
 
gacutil /i COMCallFromASP.dll
regasm /tlb COMCallFromASP.dll
 

The surprisingly when i browse the asp page I still get the same old "Hello San" instead of "Hi There San".
When I restart the machine & then only I get the desired result. Guess there's a problem in dll caching.

Pls help how to do it without restarting the machine. I also checked the folder %SystemRoot%\System32\DllCache but theres no sign of my dll there at any time.

Also after the first call to the page i find dllhost.exe is running in the taskmanager & though I unregister the dll I can't delete the .tlb file as its locked by dllhost. Why dllhost is not unloading after the call?
