I've download nopCommerce 3.80 fresh code from github and publishing it from Visual Studio 2017 framework and I'm getting DLL related error.
Here are error messages.
------ Build started: Project: Nop.Services, Configuration: Release Any CPU
SGEN : error : Could not load file or assembly ..\nopCommerce_3.80_Source\packages\EPPlus.4.1.0\lib\net40\EPPlus.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Solution is successfully building in debug and build mode.
What can be wrong with DLL at publish time?
I get the solution by unblocking the error dll file by right click of that dll in their properties option.
