问题
I have a wcf service that uses the .net System.AddIns framework to load assemblies into a seperate process and app domain. To improve performance I want to enable the Cross-Domain FastPath.
According to the documentation I need to add the LoaderOptimizationAttribute attribute to the main method of my host application. However I do not have a main method as I am using a service.
So is it possible to use the attribute? If not then how can I ensure that the addin assemblies are loaded as domain neutral?
Thanks.
回答1:
If you are hosting in IIS, you should be gettng "LoaderOptimization(LoaderOptimization.MultiDomainHost)" applied by default, and there seems to be no way to change this that I can find. If you want something else applied, you may need to roll your own host (not that hard for WCF, but certainly not as convenient or feature-rich as IIS hosting).
However, this should load all assemblies as domain-neutral - so it is probably what you want already. Make sure you are not using Assembly.LoadFrom(), as this makes it impossible for appdomains to share the JITed code.
