Orleans: "Could not load type 'Orleans.PublicOrleansTaskExtentions'..." error

[ghost]

Hi guys,
I just started to explore Orleans and tried to run "Hello, world" sample when client and host are in separate executables. However, I'm getting an error on the client side when calling Console.WriteLine(hello.SayHello("First").Result);

Full error:
"Could not load type 'Orleans.PublicOrleansTaskExtentions' from assembly 'Orleans, Version=1.2.3.0, Culture=neutral, PublicKeyToken=null'.":"Orleans.PublicOrleansTaskExtentions"

I guess some runtime component maybe is missing, but what is this? Win 7, VS 2015. Please help. Thanks.

I also had this issue because my NuGet packages were not all the same version across the solution. Maybe try checking that.

Yup, it helped. Thanks!
