Is it possible to do compiling for the Eikon Data API with C# and Visual Studio while not being c...

...onnected to Eikon?

We are very new to API-development and currently trying to retrieve realtime data via the Eikon Data APi following this tutorial: https://developers.refinitiv.com/en/api-catalog/eikon/com-apis-for-use-in-custom-applications/tutorials

Our problem is that we can not run our Visual Studio Environment directly on the PC that is connected to Eikon because of security concerns at the moment.

So the question at hand is if we can copy all the required libraries from Eikon to another PC on which we do the coding and compiling so that we get just an executable file running independently from Visual Studio in the end that can be used for connecting and data fetching on the Eikon-PC.

From my understanding so far, this is not possible.. We get the following error message:

Unhandled exception. System.BadImageFormatException: Could not load file or assembly 'Interop.EikonDesktopDataAPI, Version=9.56.0.18, Culture=neutral, PublicKeyToken=null'. An attempt was made to load a program with an incorrect format.


File name: 'Interop.EikonDesktopDataAPI, Version=9.56.0.18, Culture=neutral, PublicKeyToken=null'

According to the error message, it relates to 32-bit or 64-bit applications.

For example, the Interop.EikonDesktopDataAPI library is a 32-bit library. If you build a 64-bit application with this library, it could generate this kind of error.

You need to use this library with the x86 application.

Hi @Jotun ,

The compiling can be done without being connect to Eikon app, the steps below were reproduced and confirm that it works.

In Windows VM that does not have Eikon app installed, the code can be compiled
and executable files here can be run on another Windows (with Eikon app installed) properly

However, I'd like to recommend you the latest API that's newer than this legacy API, may I ask the reason why this API is chosen by you for the implementation, so I could recommend you the proper API, please?
