使用aspnet_merge構建VSTS會導致錯誤「元素'buildProviders'無法在應用程序級別下定義」

Question

當我使用aspnetcompilemerge在VSTS中使用msbuild參數或發佈配置文件構建asp.net應用程序時，出現以下錯誤：

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'. 

我相信這是在參考了web.config中的這一部分：

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

但有兩件事是奇怪這一點 -

1）我對這個錯誤信息的網絡研究顯示了部署或運行​​網站的問題，但我沒有部署，只是建設。

2）構建似乎成功。我可以下載工件並將其部署到本地Web服務器上，並且輸出似乎按照我的發佈配置文件中的定義進行了合併。

任何想法如何解決這個問題？

編輯 - 我能夠在新的MVC項目中重現這種情況。

發佈配置：

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 
    <PropertyGroup> 
    <WebPublishMethod>FileSystem</WebPublishMethod> 
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration> 
    <LastUsedPlatform>Any CPU</LastUsedPlatform> 
    <SiteUrlToLaunchAfterPublish /> 
    <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish> 
    <PrecompileBeforePublish>True</PrecompileBeforePublish> 
    <EnableUpdateable>False</EnableUpdateable> 
    <DebugSymbols>False</DebugSymbols> 
    <WDPMergeOption>MergeAllOutputsToASingleAssembly</WDPMergeOption> 
    <UseMerge>True</UseMerge> 
    <SingleAssemblyName>buildprovidertest.PublishedOutput</SingleAssemblyName> 
    <DeleteAppCodeCompiledFiles>True</DeleteAppCodeCompiledFiles> 
    <ExcludeApp_Data>False</ExcludeApp_Data> 
    <publishUrl>C:\Publish\buildprovidertest</publishUrl> 
    <DeleteExistingFiles>True</DeleteExistingFiles> 
    </PropertyGroup> 
</Project> 

我可以縮小它在的csproj文件<MvcBuildViews>節點。當這是true，我收到此錯誤消息。如果我將它設置爲false，則構建成功。

發佈整個生成日誌超出了計算器的字符的限制，但這裏的結尾：

Answer 1

通過該設置，你不能發佈通過VS 2015年了。

添加該代碼項目文件（xx.csproj）：

<Target Name="MvcBuildViews" AfterTargets="AfterBuild" Condition="'$(MvcBuildViews)'=='true'"> 
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" /> 
    </Target> 
    <Target Name="AfterBuild"> 
    <RemoveDir Directories="$(BaseIntermediateOutputPath)" /> 
    </Target>
