问题:

This seems to be a common problem and I found several Stack Overflow questions, but they all seem to pertain to MSBuild.

I'm trying to publish by right-clicking on my asp.net 5 rc1 project in Visual Studio and invoking a file system-based publish profile.

Its settings look like this:

<?xml version="1.0" encoding="utf-8"?>
<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>
        <ExcludeApp_Data>False</ExcludeApp_Data>
        <CompileSource>False</CompileSource>
        <_DefaultDNXVersion>dnx-clr-win-x86.1.0.0-rc1-final</_DefaultDNXVersion>
        <UsePowerShell>True</UsePowerShell>
        <IISCommand>web</IISCommand>
        <WebRoot>wwwroot</WebRoot>
        <WwwRootOut>wwwroot</WwwRootOut>
        <IncludeSymbols>False</IncludeSymbols>
        <Native>False</Native>
        <IgnoreDNXRuntime>False</IgnoreDNXRuntime>
        <publishUrl>C:\Source\CCollections\artifacts\bin\CCollections.Client.Web.Angular\Release\PublishOutput</publishUrl>
        <DeleteExistingFiles>False</DeleteExistingFiles>
    </PropertyGroup>
</Project>

This yields this output:

C:\Source\CCollections\src\CCollections.Client.Web.Angular>

I think my problem is here: C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\

I need to use a shorter path, like C:\Temp.

I've tried some of the suggestions in other stack overflow answers.

Adding <AspnetCompileMergeIntermediateOutputPath>c:\shortPath\</AspnetCompileMergeIntermediateOutputPath> to the profile doesn't appear to help.

Adding <IntermediateOutputPath>..\Temp</IntermediateOutputPath> doesn't seem to work either.

I'm guessing it's because these settings get picked up by MSBuild, but not dnu publish.

So how to I tell dnu publish to build the package in C:\Temp instead of my appdata directory?

Update: Finding the culprits: I think the files that exceed the path limit are not in the above log, and that only the successful copies are logged. To test this hypothesis:

  1. I deployed to c:\temp by running dnu publish manually
  2. Copied the files from c:\temp to C:\Users\Christopher\AppData\Local\Temp\PublishTemp

  3. Ran a script to iterate all files recursively and output path lengths that exceed 248 characters. Results:

    C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\net451\Microsoft.Extensions.Configuration.FileProviderExtensions.dll

    File path long: 249 chars

    C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\netcore50\Microsoft.Extensions.Configuration.FileProviderExtensions.dll

    File path long: 252 chars

The biggest folder is 191 characters, and with the file it's 252 characters, so that's not exceeding 240 and 260 characters, respectively.

Regardless of all this, how do I tell Visual Studio 2015 to use "C:\temp" as its temp directory, instead of my profile's temp directory?

回答1:

Change the temp output to a path with a shorter path name.

  1. Open your target .pubxml in .\Properties\PublishProfiles from a text editor.
  2. Change or add an element called PublishOutputPathNoTrailingSlash under PropertyGroup and set the value to your desired path.
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <PublishOutputPathNoTrailingSlash>C:\Temp\Publish</PublishOutputPathNoTrailingSlash>
  </PropertyGroup>
</Project>


回答2:

For new asp.net mvc 6 in project.json use

"exclude": [ "wwwroot", "node_modules" ],`
"publishExclude": [ "**.user",  "**.vspscc" ]


回答3:

I think this is what you're looking for:

When you go into the "Publish Web' dialog, you'll need to change the 'Target Location' within the "Connection" tab. (Hit the Square Box with ...) and then browse to C:\Temp and your files go there...

The dialog won't allow you to create C:\Temp on the fly, so if you haven't created it already , you'll need to do so beforehand.

I do hope this does it.
