[Mono-devel-list] Trouble reloading DLLs with XSP!

[Martin Honermeyer]

Hello,

I am using Maverick.NET, a .NET MVC-framework for web apps. This works great
with mod_mono. It utilizes it's own http-handler, like this (web.config):

<httpHandlers>
        <add verb="*" path="*.htm" type="Maverick.Dispatcher, Maverick" />
</httpHandlers>

I have controller code in dll's in the bin-directory. This means, every time
the controller code gets changed, I have to recompile the DLL and put it
into /bin.

After doing that, the next page reload looks like this:


Server error in '/mavnet' application



Description: Error processing request. 

Error Message: HTTP 500. 


Stack Trace:

I have to do
/etc/init.d/apache2 stop && killall mono && /etc/init.d/apache2 start
for the application to work again! 

I suppose this has something to do with DLL caching?
