When doing k web:

I'm getting what I think is the same error when trying to invoke the Design Time Host

/Users/jason/.kre/packages/KRE-Mono.1.0.0-beta2-10755/bin/klr /Users/jason/.kre/packages/KRE-Mono.1.0.0-beta2-10755/bin/lib/Microsoft.Framework.DesignTimeHost/Microsoft.Framework.DesignTimeHost.dll 1334 17475 36dae6ce-a6ab-4cd8-82db-b5b6c4724766

(36dae6ce-a6ab-4cd8-82db-b5b6c4724766, Error, 0) -> {
  "Message": "Argument cannot be null.\nParameter name: path1"
}

Builds 10755 and 10756 are broken for me.
