VS2010 Updating Service Reference *crazy* Slow (like 5 minutes)

Question

our team is starting to dread updating the service references in our solution because it's a 5+ minute investment. Everything is localhost inside Visual Studio's web server.

My question is - how can I debug what this problem is? It works fine once it is over, but the long delay is crazy. If I had a clue where to look, perhaps I could resolve this.

With VS2012, I ran into the same issue: it took me almost 10 minutes just to update one service reference. I just managed to fix this by re-adding the service in the following way:

• Delete the service reference.
• Right-click "Service References" and select "Add Service Reference".
• Click "Discover" (required in my case, might be different for others).
• Select the service that you want to add under "Services".
• Give the service a name (under "Namespace" at the bottom").
• Press "Advanced".
• Uncheck "Reuse types in referenced assemblies" and press "OK".
• Press "OK" to add the Service Reference.

For me, the reusage of types was the big issue: now that this is unchecked, new updates only take a few seconds. Since I couldn't find this solution anywhere else, I thought I'd just post it here in case others run into a similar issue.
