asp.net 5 (vnext) build IConfiguration missing

Question

I try to get an asp.Net 5 mvc running under mono. For the first steps i try to run an Application Template from yo My Steps are :

yo aspnet <- choose WebApplication with name MyWeb

cd MyWeb

kpm restore --source https://www.myget.org/F/aspnetvnext/api/v2/ <- done without errors

kpm build

after that command i got the following errors:

Seems like something is wrong with Microsoft.Framework.ConfigurationModel but running out of ideas how to fix this. I hope someone can give me an hint to point me in the right direction!

Thanks a lot for reading! Regards Alex

Not sure about it, but in my VisualStudio MyGet address is "https://www.myget.org/F/aspnetvnext/". Try to use kpm restore with it.

Also, got same errors after VS CTP5->CTP6 update, restore packages from beta2->beta3 had help, so it seems to be wrong package version errors.

Added: If you would get migration error, replace those usings:

/*
using Microsoft.Data.Entity.Migrations; 
using Microsoft.Data.Entity.Migrations.Builders; 
using Microsoft.Data.Entity.Migrations.Infrastructure;
*/

using Microsoft.Data.Entity.Relational.Migrations; 
using Microsoft.Data.Entity.Relational.Migrations.Builders; 
using Microsoft.Data.Entity.Relational.Migrations.Infrastructure;

i tried it with https://www.myget.org/F/aspnetvnext/ but still produced the same error. If i chance the dependencies in project.json to beta2 i got this error ´home/dev/WORKSPACE/MyWeb/MyWeb/Migrations/000000000000000_CreateIdentitySchema.cs(4,40): error CS0234: The type or namespace name 'Migrations' does not exist in the namespace 'Microsoft.Data.Entity.Relational' (are you missing an assembly reference?) ............` – Alex Mar 02 '15 at 12:12
I fixed this my moving from beta2 to beta3 on all my packages. – Josh C Mar 03 '15 at 00:35
Ah, those kind of error would be fixed pretty simplier. Them change lib struct, so you need to change /*using Microsoft.Data.Entity.Migrations; using Microsoft.Data.Entity.Migrations.Builders; using Microsoft.Data.Entity.Migrations.Infrastructure;*/ -> using Microsoft.Data.Entity.Relational.Migrations; using Microsoft.Data.Entity.Relational.Migrations.Builders; using Microsoft.Data.Entity.Relational.Migrations.Infrastructure; Just use IDE, which would show potential fixes like VS. – user1981102 Mar 03 '15 at 09:15
Thanks all for your answers, i do still have troubles..i chanced my project.json to -* istead of -beta2 or 3 to get the newest packeges and after that i still got the error about the configuration mentioned in my question. ```The type or namespace name 'IConfiguration' could not be found (are you missing a using directive or an assembly reference?)``` but i have references to Microsoft.Framework.ConfigurationModel in my project.json. have no idea what i'm doing wrong. – Alex Mar 06 '15 at 08:07
Seems you still got wrong libs. Just do as you do before - set all libs to beta 2 and change usages as I had answer before. – user1981102 Mar 06 '15 at 12:10
