我无法编译x86格式的标准"WCF服务库"

Question

如果我启动Microsoft Visual Studio,创建一个标准的"WCF服务库",并编译它,它完美地工作.

但是,如果我进入Properties..Build并将"Platform Target"设置为"x86",它将无法编译.我需要"x86",因为我需要引用一些.dll,如果选择"所有平台",它将无法工作.

Answer 1

您的问题实际上是WCF测试客户端抱怨您的WCF服务库是32位.这是因为默认情况下,WCF测试客户端始终以64位模式运行.

我没有花时间更改为WCF服务应用程序以便进行调试,而是在此博客上找到了以下步骤,使WCF测试客户端以32位模式运行 - 因此您不会看到已发布的错误.

1. 将WcfSvcHost.exe和WcfTestClient.exe从C:\ program files(x86)\ Microsoft Visual Studio 10.0\Common7\IDE复制到本地目录.当然,请保留此文件的备份副本.
2. 启动Visual Studio 2010命令提示符(开始菜单中的一个链接 - > Visaul Studio 2010)

3. "cd"到您的WcfSvcHost副本所在的目录.

4. 执行命令"corflags/32BIT +/FORCE WcfSvcHost.exe"

5. 执行命令"corflags/32BIT +/FORCE WcfTestClient"

6. 将文件复制回您找到的位置.

现在您的WcfSvcHost和WcfTestClient将以32位模式运行,您可以调试!

我找到了两种解决这个问题的好方法:

1. 安装64位版本的Matlab意味着您可以编译与64位WCF服务库兼容的64位.dll.这消除了在32位模式下编译的需要,因此在调用32位程序集时不会抛出异常.此解决方案效果很好.
2. 您可以在MSVS 2010中生成两种类型的项目:"WCF服务库"和"WCF服务应用程序".虽然您无法在32位模式下构建和运行"WCF服务库"(它只支持64位),但您可以在32位模式下构建和运行"WCF服务应用程序".
