在WCF服务上使用LoaderOptimizationAttribute [英] Using the LoaderOptimizationAttribute on a WCF service

问题描述

我有一个wcf服务，该服务使用.net System.AddIns框架将程序集加载到单独的进程和应用程序域中.为了提高性能，我想启用跨域FastPath.

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.

根据文档，我需要将LoaderOptimizationAttribute属性添加到主机应用程序的main方法中.但是，由于我正在使用服务，因此没有主要方法.

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.

那么可以使用该属性吗?如果没有，那么如何确保外接程序程序集以域中性方式加载?

So is it possible to use the attribute? If not then how can I ensure that the addin assemblies are loaded as domain neutral?

谢谢.

推荐答案

如果您在IIS中托管，则应默认应用"LoaderOptimization(LoaderOptimization.MultiDomainHost)"，似乎没有办法更改此设置我可以找到.如果您想要应用其他功能，则可能需要滚动自己的主机(对于WCF来说并不难，但是肯定不如IIS托管方便或功能丰富).

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).

但是，这应该以与域无关的方式加载所有程序集-因此它可能已经是您想要的.确保您没有使用Assembly.LoadFrom()，因为这会使应用程序域无法共享JIT代码.

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.
