发布ASP .NET Web项目后项目的dll丢失

Question

I have updated my Visual Studio 2017 two weeks ago, but I found the Project`s dll's are missing after publishing my asp .net web project. I remember it was always there before. So I want to know if this is an expected behavior or a issue?

Besides, publish type is file system publish.

Update:

Below is my Publish Profile:

<?xml version="1.0" encoding="utf-8"?>
  <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
    <WebPublishMethod>FileSystem</WebPublishMethod>
    <PublishProvider>FileSystem</PublishProvider>
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
    <LastUsedPlatform>Any CPU</LastUsedPlatform>
    <SiteUrlToLaunchAfterPublish />
    <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
    <ExcludeApp_Data>False</ExcludeApp_Data>
    <publishUrl>bin\Release\PublishOutput</publishUrl>
    <DeleteExistingFiles>False</DeleteExistingFiles>
 </PropertyGroup>

I`ma new user for SO, if I have any incorrect operation, please let me know. Thanks in advance.

So I want to know if this is an expected behavior or a issue?

I have encountered the similar issue on MSDN . I could reproduce this issue as you description on the Visual Studio 2017 15.3.0 and later.

When we build the ASP.NET web project, for example, the project name is WebApplicationTest , after build this project. The WebApplicationTest.dll will generated at WebApplicationTest\\bin folder.

However, this WebApplicationTest.dll will be deleted after you publish this web project. I test this on the previous version 15.2 and Visual Studio 2015, it works fine, that dll file still exists after publish.

So I have already submit this issue to the Visual Studio Developer Community (This issue is still under investigation), you can follow with your comments and check the feedback of this issue.
