Hi ... i want to use managed ESL in C# and downloaded the sample project of freeswitch ... in libs\esl\managed i opened the managedESL project ... but here

in ESLPINVOKE.cs we have added dll ESL by DllImport ... when i want to compile the project these ESL dlls have error because it cannot find the ESL dll ... is the issue about ESL project which is written by C++ or anything else? if it is i want to add ESL... but after adding it i cannot add esl project a reference ...
