我无法编译标准的“WCF 服务库"；x86 格式 [英] I can't compile a standard "WCF Service Library" in x86 format

问题描述

如果我启动 Microsoft Visual Studio，创建一个标准的WCF 服务库"并编译它，它会完美运行.

If I start up Microsoft Visual Studio, create a standard "WCF Service Library", and compile it, it works perfectly.

但是，如果我进入 Properties..Build 并将平台目标"设置为x86"，它将无法编译.我需要x86"，因为我需要引用一些 .dll，如果我选择所有平台"，这些 .dll 将无法正常工作.

However, if I go into Properties..Build and set the "Platform Target" to "x86", it won't compile. I need "x86" because I need to reference some .dll's that simply won't work if I choose "All Platforms".

推荐答案

我找到了两个很好的方法来解决这个问题:

I found two good methods to solve this:

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，因此它在调用 32 位程序集时不会抛出异常.此解决方案运行良好.
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".尽管您不能在 32 位模式下构建和运行WCF 服务库"(它仅支持 64 位)，但您可以在 32 位模式下构建和运行WCF 服务应用程序".

1. Installing the 64-bit version of Matlab means you can compile 64-bit .dll's which are compatible with the 64-bit WCF Service Library. This removes the need to compile in 32-bit mode so it doesn't throw exceptions when it calls the 32-bit assembly. This solution works well.
2. There are two types of projects you can generate in MSVS 2010: "WCF Service Library" and "WCF Service Application". Although you cannot build and run a "WCF Service Library" in 32-bit mode (it only supports 64-bit), you can build and run a "WCF Service Application" in 32-bit mode.
