Hi, 

I am getting error while using File Manager class in my API service in DNN, 

here is my code,

FileManager fm = new FileManager();

DotNetNuke.Services.FileSystem.FileInfo objFile = (DotNetNuke.Services.FileSystem.FileInfo)fm.AddFile(folderInfo,newUser.Profile.Photo.ToString(), InputBin, true); 

Included DotNetNuke.Services.FileSystem namespace

While building the service(class library project) I am getting error,

The type 'DotNetNuke.Services.FileSystem.FileManager' has no constructors defined 

but the constructor is defined in class
