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，它使用 .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 属性添加到我的宿主应用程序的主要方法中.但是我没有主要方法，因为我正在使用服务.

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.

那么可以使用属性吗?如果不是，那么我如何确保加载程序集作为域中立加载?

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

如果你在 IIS 中托管，你应该默认应用 gettng "LoaderOptimization(LoaderOptimization.MultiDomainHost)"，而且似乎没有办法改变这个我能找到的.如果您想要应用其他东西，您可能需要推出自己的主机(对于 WCF 来说并不难，但肯定不如 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，这应该将所有程序集加载为域中立的 - 所以它可能已经是你想要的了.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.
