问题
Does anyone know if it is possible to setup a WCF service running on IIS 7.5 so it would start automatically (and not waiting for the first request to come in), without the installation of AppFabric?
回答1:
You can achieve this by using the module IIS 8.0 Application Initialization, which is compatible with IIS 7.5:
IIS 8.0 Application Initialization
Here's the download link for IIS 7.5: Application Initialization Module for IIS 7.5
An alternative would be to write a small app which calls your service, you could then schedule that to run regularly or when your app pool is recycled.
