Publishing issue Microsoft.NET.Sdk.Razor.StaticWebAssets.targets(593,5) MSB3026

I am facing a strange issue while publishing a site. The site is already published and I am just trying to update it. I am using the same publishing profile which worked perfectly well so far just 2 days back.

Initially it is a warning like this :

00:24:28:161    C:\Program Files\dotnet\sdk\7.0.100\Sdks\Microsoft.NET.Sdk.Razor\targets\Microsoft.NET.Sdk.Razor.StaticWebAssets.targets(593,5): Warning MSB3026: Could not copy

"C:\Users\user\Desktop\ASP.NET projects\AuthSystem-Login - Version17_WIPExcelChart_testingLocalNuget\wwwroot\obj\Release\net6.0\PubTmp\Out\wwwroot\DataFile\ABCD.xlsx" to "C:\Users\user\Desktop\ASP.NET projects\AuthSystem-Login - Version17_WIPExcelChart_testingLocalNuget\obj\Release\net6.0\PubTmp\Out\wwwroot\obj\Release\net6.0\PubTmp\Out\wwwroot\DataFile\ABCD.xlsx". Beginning retry 10 in 1000ms. Could not find a part of the path 'C:\Users\user\Desktop\ASP.NET projects\AuthSystem-Login - Version17_WIPExcelChart_testingLocalNuget\obj\Release\net6.0\PubTmp\Out\wwwroot\obj\Release\net6.0\PubTmp\Out\wwwroot\DataFile\ABCD.xlsx'.

After some time, this warning becomes an error message :

Error MSB3021: Unable to copy file

"C:\Users\user\Desktop\ASP.NET projects\AuthSystem-Login - Version17_WIPExcelChart_testingLocalNuget\wwwroot\obj\Release
net6.0\PubTmp\Out\wwwroot\DataFile\ABCD.xlsx" to "C:\Users\user\Desktop\ASP.NET projects\AuthSystem-Login - Version17_WIPExcelChart_testingLocalNuget\obj\Release\net6.0\PubTmp\Out\wwwroot\obj\Release\net6.0\PubTmp\Out\wwwroot\DataFile\ABCD.xlsx".

This happens for all the files in Datafile folder.

What I tried :

  1. I removed the files in \wwwroot\DataFile folder since those were just some output files and not needed. But publishing even after that did not solve the problem.
  2. I cleaned the solution as well.

As far as I remember, I did not change any settings from the last time (when it worked fine). Is there any option where I explicitly tell not to copy the files inside DataFile folder? May be that will solve this issue.

Solution

  • In my case, I did a couple of things after a lot of trial and error and it's working now.

    1. Changing the path (shortening it). I copied the entire project to some new folder having a short path (e.g. C:/user/admin/tmp). Earlier it was longer.

    2. But the same path was working 2 days back and as I mentioned I was just updating the project. Therefore my guess was that there was some other setting which got changed (how I don't know). Since I had installed a couple of memory profiler in the last 2 days, I assumed it might had some impact. I uninstalled those.

    Honestly I am not sure of this behavior but it's working now.
