QuickBooks provides a SDK, currently SDK14.0 with a dll, interop.QBFC14. I have not been able to find the file QBFC14lib?

Question

I found some code to register a dll and produce a typelib:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe /tlb /codebase Interop.QBFC14.dll, but it gives the following:

RegAsm : error RA0000 : CLR assembly 'Interop.QBFC14.dll' was imported from a type library and cannot be re-exported to a type library.

I don't recall having to do anything to produce QBFC13Lib when I upgraded it a year or two ago.

QuickBooks Desktop Pro 2020 Release R10P

Microsoft Visual Studio Community 2019 Version 16.8.4

An example of the error messages that comes with the missing 13 lib is:

Cannot find the interop type that matches the embedded interop type 'QBFC13Lib.ENVisibleIfNot'. Are you missing an assembly reference?

The SDK13 version still works, but I need to get this done in due course.

Answer 1

I started wondering more about that RegAsm error and decided to try substituting 'using Interop.QBFC14' for 'using QBFC13lib'. Much to my surprise, it seems to work. I have not yet tested extensively, but it compiles and opens a session with QuickBooks as it should.

Presumably somewhere in the QBSDK14.0 documentation there is an discussion of this name change, although I wasted a lot of time looking for that explanation.
