Asp.net 使用aspnet生成VSTS“U合并导致错误”；元素'；建筑供应商'；无法在应用程序级别下定义“；

当我在VSTS中使用aspnetcompiler在msbuild参数或发布配置文件中生成asp.net应用程序时，会出现以下错误：

MyProject\obj\release\aspnetcompilemerge\source\web.config(129,0): Error ASPCONFIG: The element 'buildProviders' cannot be defined below the application level.
Process 'msbuild.exe' exited with code '1'.

我相信这是指web.config的这一部分：

<buildProviders>
    <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
</buildProviders>

---

使用该设置，您也无法通过VS 2015发布它

将此代码添加到项目文件（xx.csproj）：

我无法在MVC 4和Web表单项目（VS2015）中重现此问题。（将该buildProvider添加到system.web>编译部分）。你的项目是什么类型的？发布配置文件的详细代码是什么？你能用一个新项目重现这个问题吗？你能在这里分享详细的构建日志吗？@starain MSFT谢谢你的时间。我在问题中添加了更多信息。我创建了一个新项目来处理设置，它似乎与
csproj设置有关。谢谢。我可以发誓我的配置在本地工作，但显然不行。
