asp.net mvc - Exception when run Aspnet Mvc app on OS X -

i'm trying run samples aspnet 5 on os x: git clone https://github.com/shirhatti/home.git

when build project hellomvc -- 'kpm build' -- it's ok. run app using 'k kestrel' , see next error:

there no exact problem in google. tried reinstall kvm, delete , checkout nuget deps.

updated: similar behavior on windows when seek run same project 'k web':

seems problem in 1 (or more) of referenced in microsoft.aspnet.mvc.* assemblies. disassemble of defaultassemblyprovider microsoft.aspnet.mvc.core. guess problem in ilibrarymanager's implementations getreferencinglibraries() method. can't find implementation.

i had similar problem on windows , found wrong kre active.

executing kvm list shows list of kre. in case 1.0.0-alpha4 version active instead of more recent beta version.

switching default kvm utilize default sorted out me.
