Question

Workstation.Current.GetLocalWorkspaceInfo(string)返回与给定本地目录关联的WorkspaceInfo对象。

所以，我编写了一个简单的程序，显示给定本地目录名称的工作区名称。它在我的机器上运行良好，但在另一台机器上不起作用。

两者的区别在于我的运行VS2012而另一个运行VS2013。对于我的生活，我无法理解。两个工作区都链接到同一个TFS服务器2010。

在阅读TFS API: GetLocalWorkspaceInfo always returns null之后，我将Microsoft.TeamFoundation.XXX引用替换为在第二台机器上找到的引用，它再次起作用。但是，当然，它停止在我的机器上工作。

这不是正确的方法。我一定是在做错事。

我希望单个可执行文件适用于两台计算机而无需借助反射。我的问题很简单 - 如何？

完整的源代码可以在这里找到 - https://bitbucket.org/markkharitonov/tfsinsanity/src。基本上，两个项目共享完全相同的源代码，但使用了一组不同的依赖项。

主要源代码是：

private static Workspace GetWorkspace(string wsRoot, string wsName, string wsOwner)
{
    var coll = new TfsTeamProjectCollection(new Uri("http://torsvtfs01:8080/tfs/DefaultCollection"));
    var vcs = (VersionControlServer)coll.GetService(typeof(VersionControlServer));
    WorkspaceInfo wsInfo;
    if (wsRoot == null)
    {
        Console.WriteLine(Workstation.Current.Name);
        wsInfo = Workstation.Current.GetLocalWorkspaceInfo(vcs, wsName, wsOwner);
        if (wsInfo == null)
        {
            throw new Exception(string.Format("Failed to identify the workspace {0};{1}", wsName, wsOwner));
        }
    }
    else
    {
        wsInfo = Workstation.Current.GetLocalWorkspaceInfo(wsRoot);
        if (wsInfo == null)
        {
            throw new Exception(string.Format("Failed to identify the workspace corresponding to \"{0}\"", wsRoot));
        }
    }
    return wsInfo.GetWorkspace(coll);
}

这是如何在我的机器上运行的（VS2012）：

Answer 1

在这种情况下，方法签名应该是相同的，您只需要担心首先引用正确的DLL。您应该能够链接到较新的DLL并使用绑定重定向为安装了VS 2012的用户加载DLL。

We used this method successfully in a previous product to provide TFS 2005 and 2008 compatibility.

简而言之，您创建了一个自定义程序集解析程序。在这里，当我们无法加载与之链接的VS 2013版本时，我们将尝试从VS 2012加载所有Microsoft.TeamFoundation.* DLL：

AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(ResolveAssembly);

public static Assembly ResolveAssembly(object sender, ResolveEventArgs args)
{
    String[] arguments = args.Name.Split(new string[] { ", ", "," }, 
        StringSplitOptions.RemoveEmptyEntries);
    String assemblyName = arguments[0];

    if(assemblyName.StartsWith("Microsoft.TeamFoundation.", StringComparison.CurrentCultureIgnoreCase))
    {
        return Assembly.Load(assemblyName + ", Version=11.0.0.0");
    }

    return null;
}

（请注意，您应该检查所请求的版本号并将文化信息传递给加载程序，如博客文章中所述，但此代码段应足以让您入门。）

通过将CopyLocal属性设置为Always，将项目引用的TFS程序集添加到可执行文件中。

如何调用Workstation.GetLocalWorkspaceInfo的方式适用于使用VS2012的用户以及使用VS2013而不使用反射的用户？
