I want create sample application in dot net core which are using Microsoft.Office.Interop.Excel reference to read the excel and run the some Macros from them and I need to deploy this small application to docker Linux host.
So is it possible?
Hi @nandkishor ingavale - Can you please share the docker file. I have to implement the same functionality. It will be of great help.

Yes it is supported as of .NET 3.0 as discussed in the Github repo for .NET core. However the caveat, as with most things .NET Core, is that it would probably only work on Windows as the other platforms don't have Office. There is/was an Office for Mac so maybe it'd work there but the COM stuff has always been Windows only so I doubt it would work anyway.
Thanks for update. I deployed same application on windows docker container its working fine but on Linux container its showing exception at time of build image.
Office doesn't run on Linux and therefore the interop assemblies won't work anyway. For your Linux dist you'll have to use an alternative solution. Not sure if that is why your container build is failing but most container builds do a compilation so it makes sense.
You could consider looking into OpenXML instead. It is supposed to work on all .NET platforms but it is unclear if it works on all OS platforms. However it does support manipulating Office documents, but not Office itself (which cannot be installed on Linux).
Interop is the .NET wrapper for the ActiveX interface of Excel and ActiveX (or COM) is 100% pure Windows world; don't think this works on Linux.
Thanks for update. I will use windows container.
