Migration Query from NET Express to Visual COBOL

Hi 

We have an ABC.EXE component build in Net Express 5.1.

It contains 10 programs. Out of them 9 programs are Native Procedural program. They are reading files and updating the files.

One program(NETCall) build with +OOCTRL(+p) compiler directive and it is calling an .NET 4.5 DLL, To make database entry.

We are trying to migrate the whole component in to VIsual COBOL by creating an Native - Console Project.

While building the solution ,we are getting errors in NETCAL program at various places like creating an object of .NET class and calling the .NET method.

We are not able to resolve this error. Please let us know how we can solve this problem.

Thanks 

Charan
