为什么我可以在visual studio 2015中生成但不发布我的.net webapp？我可以在昨天发表

直到昨天，我还可以发布我的.net web应用程序

但我开始收到错误：C:\Program Files（x86）\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Publishing.targets（149,5）：错误：访问被拒绝

这是编译和发布活动的日志，即编译works文件。 当我在Visual Studio 2015中单击“IIS Express”时，我可以运行该web应用程序，但我无法发布它

“错误”选项卡中有2个错误

Severity    Code    Description Project File    Line    Suppression State

Error       Access is denied    [MyProjectName]     0   

Error       Invalid path    [MyProjectName] C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Common.Targets  262 

“Microsoft.DotNet.Common.Target文件”的第262行为

<Dnx
      RuntimeExe="$(SDKToolingExe)"
      Condition="'$(_DesignTimeHostBuild)' != 'true'"
      ProjectFolder="$(MSBuildProjectDirectory)"
      Arguments="$(_BuildArguments)"
      />

我错过了什么

编辑：

我设法编辑了Microsoft.DotNet.Common.Targets以删除第262行

第二个错误消失了，但第一个错误仍然存在。 C:\Program Files（x86）\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Publishing.targets（149,5）：错误：访问被拒绝

Microsoft.DotNet.Publishing.targets的第149行是：

 <Publish
      RuntimeToolingDirectory ="$(SDKToolingDirectory)"
      ProjectFolder="$(MSBuildProjectDirectory)"
      Project="$(KPackWorkingDirectory)"

朋友，请尝试使用“以管理员身份运行”选项打开VS2015。很抱歉，这无法解决问题。我总是以管理员身份打开我的解决方案。为了确保我在administrator中打开了VS 2015，然后打开了解决方案。。。同样的错误。嗨，我的朋友。您可以尝试创建一个新的配置文件，然后再次发布。我尝试创建一个新的发布配置文件，但出现了相同的错误。我设法编辑了Microsoft.DotNet.Common.Targets以删除第262行。错误消失了，但第一个错误仍然存在。但现在我有了比“拒绝访问”更好的描述C:\Program Files（x86）\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Publishing.targets（149,5）：错误：拒绝访问
