is outsystems extension suppport DevExpress dll component?

Dear ,

now we are try to build out own extension and if using .net build in dll was fine but after we try to use DevExpress then get below error  : 

Could not load file or assembly 'DevExpress.Data.v20.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a' or one of its dependencies. The system cannot find the file specified. 

does outsystems extension support to reference non .net build in dll ?

anyone try and success before? many thank if any advise.



Hi Chris,

Could you share a screenshot of the reference properties of the DLL?



Dear Daniel,

thanks for your reply, here you are the screen capture.

for your information, we can use this DevExpress dll normal from local, so the dll is fine.



See the path property, that is the issue I think.

The DLL, or a copy of it, needs to be located in the extension project folder which is a subfolder of the OutSystems Integration Studio.

Dear Daniel,

So the situation is now the path are not indicate to /Bin folder path but reference to C:/ path ?

Do we need to specific the path for these DevExpress Dll when processing ? 


If I look at other extensions that use non-operating systems or outsystems provided dll's (like system.dll etc.) their path is in the temporary folder that is used by Integration Studio to help you build the extension:

C:\Users\yourusername\AppData\Local\Temp\some guid  to uniquely identify your extension VS project \Source\lib\external-dll-filename.dll
