You should download the updated documentation for Dynamics NAV R2 which contains a guide for the new DotNet interop feature.

Look for the file NAV 2009 R2 Help Update.zip on http://www.microsoft.com/downloads/en/d ... 93c9ac282a

In the CHM file, browse to the section "Extending Microsoft Dynamics NAV Using Microsoft .NET Framework Interoperability" in "Developer Updatges for Microsoft Dynamics NAV R2"

The document contains a number of examples that can help you get started, if you need additional help, please feel free to contact me.

When I download,extract and run this file it doesn't display the text on the right hand window, it says "This program cannot display the webpage". Any thoughts?

I had the same problem when I was trying to open chm from network drive. After copying it to local drive it open without problems. Also check file attributes and permissions.

Hi,

it seems there are only samples with .NET framework code. It would be nice to see a sample with custom .NET assemblies.

I'm always getting an unspecific error when I try to use a custom constructor. NAV is telling me that it can't create an instance of my .NET object.

Hi
Sounds like the custom assembly is missing in the run time environment. Remember to deploy the assembly to the Add-ins folder within your servers installation folder. Find the folder that contains Microsoft.Dynamics.Nav.Server.exe and create a subfolder named Add-ins in that folder. Copy your assembly and all dependencies (that does not exist in the GAC) to the Add-ins folder.

If you want to run the custom assembly client side, you will have to deploy it to teh Add-ins folder relative to the client folder.

Make sure you are using .net 3.5 and not 4.0. 4.0 does not work. I am not sure about versions before 3.5 but I am guessing they would work.

Confirmed: Any .NET Version 3.5 and before will work for RTC Add-Ins and .NET Interop solutions.
.NET 4.0 does not work, because the host process (RTC / Service) is not running on .NET 4.0 in shipping versions of NAV.

Thanks.

The problem was indeed that the assembly has to be in Client/Add-In and Service/Add-In.
