Bug running HelloWorld

[Sandman83]

Trying the HelloWorld starting example from
http://dotnet.github.io/core/getting-started/
An error occurs running the last command dnx . run
The output is

System.InvalidOperationException: Unable to load application or execute command '.'. Available commands: me.
   at Microsoft.Dnx.ApplicationHost.Program.ThrowEntryPointNotfoundException(DefaultHost host, String applicationName, Exception innerException)
   at Microsoft.Dnx.ApplicationHost.Program.ExecuteMain(DefaultHost host, String applicationName, String[] args)
   at Microsoft.Dnx.ApplicationHost.Program.Main(String[] args)

   at Microsoft.Dnx.Host.RuntimeBootstrapper.Execute(String[] args, FrameworkName targetFramework)
Trace/BPT trap: 5

The used configuration is

Active Version              Runtime Arch OperatingSystem Alias
------ -------              ------- ---- --------------- -----
       1.0.0-beta6          mono         linux/darwin    default
  *    1.0.0-beta7-12356    coreclr x64  darwin          
       1.0.0-beta7-12356    mono         linux/darwin    

However, using the beta6 mono runtime seems to give right results.

dnx . run

Think the sugar syntax has changed. Try dnx run, or expand it to the full (type dnx for help).

dnx run

gives

dnx run gives System.IndexOutOfRangeException

Yeah, thats another story. The latest bits are obv shaky from day to day, but with dnx run you are at least past the initial, reported problem (which was caused by the errornous command-line).

Sorry I can't help you with this next one too.

[moozzyk]

@Sandman83 - looks like you hit this #2442.
/cc @BrennanConroy

[BrennanConroy]

Ya, latest X-Plat CoreCLR bits are not usable, sorry.

[trotyl]

The same System.IndexOutOfRangeException: Index was outside the bounds of the array. problem as above with the exact procedure in https://github.com/dotnet/coreclr/blob/master/Documentation/install/get-dotnetcore-dnx-osx.md
With dnvm 1.0.0-beta7-10410, dnx coreclr 1.0.0-beta7-12364.

[BrennanConroy]

This should be fixed with the latest dnx's

[BrennanConroy]

beta8-15138 or beta7-15131
