Studio not referring to dependent dll present in nuget

I created a dll - DLL A and bundled into a nuget package for some of my custom actions using C#(Visual Studio)… This nuget package is dependent on another dll - DLL B which I have add in the same nuget package. I imported this nuget package into UIPath studio via manage packages. When I invoke the methods using Invoke Method it is throwing an exception " The system cannot find the file specified in the path". because it is not able to refer to DLL B which is in the package. How to resolve this issue?
