Issue in accessing the C# code from X++

(0) ShareShare

Posted on by Mohamed Meeran 1,920

Hi Guys,

I have developed a logic in C# (Dll) and accessing the objects from X++. The server is with TFS version control. I have new server and added the same with TFS version. When I downloaded the codes to the new server, I am receiving an error as

THE METHOD methodname HAS NOT BEEN DECLARED.

I am passing four values for four methods from AX to C#.

Am receiving the error in fourth method.

When I put dot next to the instance name of the C# the method does not comes in the dropdown, when I checked the same in C# solution the method exists.

I have also used .net reflector to open the dll and check for the method, it exists.

Please guide me. Thanks.

    If it's a C# project added to AOT, check whether it's set up for deployment to client, rebuild the project and restart the client.

    If it's an independent assembly, install it into a location where AX can find it.

    I tried Martin, but still the issue persists.

    The steps I have followed

    I have opened the project from AOT, cleaned, build and added to AOT.

    Closed AX.

    Copied the assembly in the necessary location.

    Opened AX and compiled the particular class and I have received the same error.

    All right, so it's a project in AOT. Then the next question is whether it's set up to deploy the assembly to client. If it isn't, building the project can't deploy anything. If it is, don't try to by yourself, merely verify that it's been deployed (to %USERPROFILE%\AppData\Local\Microsoft\Dynamics AX\VSAssemblies).

    When the deployment is done and if it still doesn't work, we'll move to another phase of analysis.

    Hi meeran,

    No Martin, it is not. Manually the dll's after building the VS solution are pasted to client and server bin folder. I am doing this for very long time all went fine. When I moved the updated code to another server which has the old code, have received the error only in the updated section of dll. Say unable to access the new method created in C# project from AX. Lists only the old methods.

    Why exactly do you waste time doing manually what the system can do for you automatically?

    Anyway, your description reveals that you didn't do the deployment correctly. Verify again that you copied the DLL to a folder where the AX client can find it. Ensure yourself that the old one was overwritten. And don't forget to restart the client.

    I have same issue where c# VS project is added to AOT and set is deployed to server and =yes. Its working fine in dev box but  when same model is deployed to other instance i am getting compile error.

    Do i need to manually deploy it after model deployment?
