C＃windows应用程序 - 希望将我的业务和数据层保存在单独的机器中并使用WCF访问它

Question

I am working on a windows application already splitted up into layers(UI, Business and Data Layers). I want to keep my business and data layer in a seperate machine, so that user need to have the UI layer installed in his machine. Is it a good idea to use the WCF web service and access my business layer and data layer through it?

Answer 1

Actually it depends...

If it is only thin UI layer you want to move to a user machine and then call your services with each user action then I think it is a really bad idea. Because in this case a user has a windows application which in fact responses like a web application (of course if you think of communicating via internet not local network). So if I were you I would better create a multi-tenant web application which uses all your already implemented business logic. Also this would prevent you from having a lot of versioning issues because you have full control of you UI application unlike with windows application when you have to deal with multiple versions of your solution or at least to implement some error handling logic to make all users upgrade to a newer version to proceed working.

However, if your application mostly work offline and there is only some logic which really needs to be common for all users then your choice should be WCF. It provides you with all the tools for securing and configuring the communication channel on the configuration level without even rebuilding your application. There are also a lot of built-in options for binding and behavior configuration.

Hope it helps.

使用wcf是一个很好的主意，它可以很好地工作但是维护软件并在多台机器上保持最新状态将成为一个问题，因为客户数量不断增长.....如果你在本地网络工作也许您应该考虑在终端服务器上安装应用程序并通过rdp会话连接，或者您可以创建UI的Web版本
