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:
- I deployed to c:\temp by running dnu publish manually
- Copied the files from c:\temp to C:\Users\Christopher\AppData\Local\Temp\PublishTemp
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.
- Open your target
.pubxmlin.\Properties\PublishProfilesfrom a text editor. - Change or add an element called
PublishOutputPathNoTrailingSlashunderPropertyGroupand 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.
