命令行MSBuild無法編譯代碼

Question

任何人都可以告訴我爲什麼命令行msbuild無法構建此代碼？

public SourceControlHandler(string sourceControlUser = null, string sourceControlPassword = null, string sourceControlDomain = null) 
     {  
      var client = new SvnClient(); 
      if (!string.IsNullOrEmpty(SourceControlUser) && !string.IsNullOrEmpty(SourceControlPassword)) 
      { 
       client.Authentication.Clear(); 
       client.Authenticatio​n.UserNameHandlers += delegate (object sender, Sv​nUserNameEventArgs e) 
       { 
        e.UserName = SourceControlUser; 
       }; 
      _svnClient = client; 
     } 

的錯誤是：

1) -> 
D:\DEV\EP.BuildAndDeploy\EP.BuildService\EP.BuildService.csproj" (default targ

的Visual Studio 2015年沒有問題，編譯它，代碼不拋出任何運行時錯誤。 列出的代碼從第38行開始。因此MSBuild/CSC正在抱怨 - 第一個錯誤 - 關於第二個點：client.Authenticatio n.UserNameHandlers;

想法？

在Authentication之間o和n之間有一個不可顯示的字符。 使用鍵盤上的箭頭鍵可以看到它。
