I was wondering if there is any simpler way to create a executable file of the taskpane addin?
Apart from the solutions provided in https://docs.microsoft.com/en-us/office/dev/add-ins/publish/publish, So that I could generate a quick file to check installing on my machine
Sorry if my english is not good though
Office web add-ins can't be installed using standard techniques such as Windows installer. It is just a web application which should be hosted somewhere on the server and then the manifest file added to the Office365/Exchange tenant or just published to the store. So, methods described in the article are valid. There is no other mechanisms for distributing them individually like you could do in case of COM add-ins.
The methods discussed in that article are the only way to distribute an Office Add-in.
