Dear Community,

i got a question about using .Net DLL's in Navision Classic Client.


I wrote a test dll for testing how to implement da dll file into navision,
that it is able to use as automation variable.

Picture of my C# class (developed in .net 4.5.2)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I added my dll with regasm and into the gac with following commands:

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" "C:\Users\Jean-Pierre.Schmidt\Documents\Visual Studio 2015\Projects\DemoDLLA\DemoDLLA\bin\Release\DemoDLL.dll" /tlb:"C:\Users\Jean-Pierre.Schmidt\Documents\Visual Studio 2015\Projects\DemoDLLA\DemoDLLA\bin\Release\my.tlb"

"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\gacutil.exe" /i "C:\Users\Jean-Pierre.Schmidt\Documents\Visual Studio 2015\Projects\DemoDLLA\DemoDLLA\bin\Release\DemoDLL.dll"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here you can see how it looks like, when i selected my DLL.

    Use .net 2 or 3.5 to register the dll instead of 4.

    With .Net 3.5 and 2.0 it isn't working, too.

    Any other suggestions?

    You simply need to post the dll in this folder:

    C:\Program Files (x86)\Microsoft Dynamics NAV\**\RoleTailored Client\Add-ins

    Where ** is your version no of dynamics nav. Like in case of 2013R2 it is 71 etc.

    By adding this, you will be able to see the dll in navision.

    Once the DLL is available there you can go in NAV make a new Datatype of DotNet and there you will find your DLL with all Methods you have declared in C#.

    Let me know if you have any other question.

    Dear zohaibu95,

    for RT Client    . I'm not a specialist, if I'm wrong please correct me.

    Here is the file:

    Finding my DLL and Class is working fine, but using it throws this error:

    Translated Error: The .NET-Interoptyp can not be used for the code in the classic CSide-Runtime. :/
