`IOC' does not exist in the namespace `uFrame'？

[xclouder]

I clone this project into my Proj/Assets/ directory, but got
error CS0234: The type or namespace name IOC' does not exist in the namespaceuFrame'. Are you missing an assembly reference?

my unity3d version is:5.3.0f4

I got the same error with the same unity3d version .
