c# - 如何在不重启的情况下生成服务模型元数据

Question

我有简单的 WCF 服务应用程序(基于本教程:Getting Started)。我的问题是，当我向我的应用程序添加一个函数并想使用以下命令重新生成 Proxy.cs 文件时:

C:\kod>svcutil.exe/language:cs/out:Proxy.cs/config:app.config http://localhos
t:8000/PBMB

我得到以下结果。我知道重新生成这些文件的唯一解决方案是重新启动我的计算机。但是每次我改变任何东西时都这样做是令人沮丧的。谁能帮忙？

结果:

Microsoft (R) Service Model Metadata Tool [Microsoft (R) Windows (R) Communication Foundation, Version 4.0.30319.1] Copyright (c) Microsoft Corporation. All rights reserved.

Attempting to download metadata from 'http://localhost:8000/PBMB' using WS-Metad ata Exchange or DISCO.

Generating files... Warning: No code was generated. If you were trying to generate a client, this could be because the metadata docu ments did not contain any valid contracts or services or because all contracts/services were discovered to exist in /reference assembl ies. Verify that you passed all the metadata documents to the tool.

Warning: If you would like to generate data contracts from schemas make sure to use the /dataContractOnly option.

(免责声明，我绝不是这方面的专家，但我很感兴趣并在谷歌上搜索了一下)

当您对服务进行更改并重新启动时，运行服务的帐户是否可能发生变化？就像当您启动计算机时默认情况下它在 IIS 下运行，但是当您修改它时，您会在 Cassini 或类似的东西下启动它？

我问的原因是因为根据this blog post WCF 服务需要对临时文件夹具有写入权限，因为它执行一些动态代码生成并需要一些地方来存储它。

只是一个值得考虑的想法。
