The problem is that the c++/CLR dll (which is in the Data subfolder) ONLY looks in the executable directory (the main Sierra Chart folder) for any c# dlls. When it doesn't find them there, it throws you the eefileloadexception.
IMHO the "proper" way to handle this would be with a ResolveEventHandler like the one below (copied from http://www.cplusplus.com/forum/windows/196600/. But SC would have to give us a hook that was called once, and preferably only once, during start-up (or at least sometime you call the study) so we could hook up the event.


using namespace System;

public ref class AssemblyResolver{
public:
static System::Reflection::Assembly ^ResolveEventHandler(System::Object ^sender, System::ResolveEventArgs ^args){
auto sb = gcnew System::Text::StringBuilder();
sb->Append(GetAssemblyDirectory());
const char * const name = "\\required_assembly.dll";
for (auto p = name; *p; p++)
sb->Append((Char)*p);
return System::Reflection::Assembly::LoadFrom(sb->ToString());
}

//Returns the containing directory of the assembly that contains the function.
static String ^GetAssemblyDirectory(){
auto codeBase = System::Reflection::Assembly::GetExecutingAssembly()->CodeBase;
auto uri = gcnew UriBuilder(codeBase);
auto path = Uri::UnescapeDataString(uri->Path);
return System::IO::Path::GetDirectoryName(path);
}
};

API Instance *initialize(){
auto domain = System::AppDomain::CurrentDomain;
domain->AssemblyResolve += gcnew System::ResolveEventHandler(AssemblyResolver::ResolveEventHandler);

//(Application-specific stuff)
}
