dnu problem when running dev HelloMvc and HelloWeb on Mono 3.12.1

[witterlee]

Ubuntu 12.04 LTS

apt-get install mono-complete (3.12.1)
runtime: dnx-mono.1.0.0-beta5-11400

dnx . run , Console sample is ok.

when dnx . kestrel has a message like:

root@ubuntu:~/Home/samples/HelloWeb# dnx . kestrel
System.InvalidOperationException: Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1':
   Kestrel 1.0.0-beta3

Searched Locations:
  /root/Home/samples/{name}/project.json
  /usr/lib/mono/4.5/{name}.dll
  /usr/lib/mono/4.5/Facades/{name}.dll

Try running 'dnu restore'.

  at Microsoft.Framework.ApplicationHost.Program.Main (System.String[] args) [0x00000] in <filename unknown>:0 

After run "dnu restore",only give more information that
/root/.dnx/packages/{name}/{version}/{name}.nuspec

Obviously you haven't read "Tip #1" from the blog post. I suggest doing that.

I use dnvm upgrade get the newest dnx and git clone the newest code from https://github.com/aspnet/Home, then use dnu restore to get the project.json nuget package.
anything wrong,guy?

Use the dev branch for samples that work with beta4/5
