[victorhurdugaci]

Run this on a project:

dnu install Microsoft.AspNet.Hosting 1.0.0-beta5 --source "https://www.myget.org/F/aspnetvnext/api/v2" --source "https://nuget.org/api/v2/" --no-cache

Result:

@ChengTian any ideas?

[ChengTian]

Looks like a regression. Investigating.

[ChengTian]

This regression makes dnu install unusable, should be fixed ASAP.

Agreed
