Since updating my workstation with windows 7 ultimate (from XP), I experience a delay of about 40 seconds to after calling Open() on an instantiated ServiceHost.
When I run the exe with the same config on the host windows server it opens immediately. Any ideas about this behavior on my workstation?
Running Visual Studio 2010 Ultimate, Windows 7 Ultimate x64, 8gig RAM.
Update.... I found that removing the 1. service mex endpoint (leaving a single net.tcp endpoint) 2. service host http base address 3. service behavior httpGetEnabled
resolves the issue. If I change the net.tcp endpoint to use basicHttpBinding, Open takes 40 seconds. But why is there a 40 second delay to set up the endpoint with the http endpoint (mex or service-contract)?
