Publish from VS 2015

Using Visual Studio 2015 Update 1, trying to publish an ASP.NET 5 web application to a local disk folder. Partway through the publish it stops and shows in the error panel "Data error (cyclic redundancy check)."

When reviewing the output this is the last couple of lines:

Copying to output path C:\Users\[username]\AppData\Local\Temp\PublishTemp\WebApplication1111
DNU(0,0): Error : Data error (cyclic redundancy check).

Any ideas how to get past this error?
