Question

为什么第三方应用程序在命令shell中启动时的行为与使用System.Diagnostics.Process.Start("ThirdPartyApp.exe");在C＃应用程序中启动时的行为不同？
有没有办法在C＃中启动一个应用程序，以便它在完全时表现得像从命令shell启动时那样？

详细信息： 我在我的PC上安装并运行了第三方.NET 4.0应用程序（没有可用的源代码）。它附带在IIS中运行的Web服务。我编写了一个C＃应用程序，它使用SOAP消息来调用这些Web服务。（两个应用程序都安装在同一台PC上运行。）如果第三方应用程序在启动我的应用程序之前运行，我就可以毫无问题地与它进行通信。如果第三方应用程序在启动我的应用程序之前未运行，我希望能够启动它。我尝试了以下代码：

if (!System.Diagnostics.Process.GetProcesses().Select(rec => rec.ProcessName).Contains("ThirdPartyApp"))
{
    System.Diagnostics.Process.Start("ThirdPartyApp.exe");
}

如果我尝试通过我的SOAP客户端访问Web服务：

using (var soapClient = new ThirdPartyAppSoapClient())
{
    soapClient.SomeWebService();
}

在调用SomeWebService时，第三方应用会抛出以下异常：

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\M
icrosoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure lo
gging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus

如果第三方应用程序在我启动应用程序之前已经运行，我可以正常调用SomeWebService，所以我发现很难相信缺少依赖项;但为了幽默这个第三方应用程序，我将丢失的文件复制到指定的文件夹中，看看是否能解决问题。有关缺少的依赖项的第一条错误消息随后更改为InvalidCastException，但第二条错误消息（System.ApplicationException: Object synchronization method was called from an unsynchronized block of code.）仍然显示并保持不变。

了解我做错了什么的帮助，以及我如何让这个第三方应用程序无论是从C＃应用程序内部还是外部启动都行为相同，我们将不胜感激！

它可能与运行应用程序的用户上下文有关，例如，如果您以管理员身份运行应用程序Process.Start将尝试在相同的上下文中启动该过程。

请发布InvalidCastException

从另一个.NET 4.0（C＃）应用程序启动时，.NET 4.0应用程序抛出ApplicationException
