Where does the Azure DevOps/TFS cache extensions data

Question

I have developed Azure DevOps extension and published it to marketplace. Recently I have came across mandatory UI changes. While performing dev testing, I have noticed that once I install new extension (with UI changes) it still showing old UI components. For example, let’s say I have string input named “Name” and I have replaced it with “Full Name”. I still see my old input which is “Name”.

Old :

{
            "name": "name",
            "type": "string",
            "label": "Name",
            "required": true            
}

New:

{
            "name": "fullName",
            "type": "string",
            "label": "Full Name",
            "required": true            
}

I removed temp files under below locations, but issue persists.

C:\Users\<< User Name >>\AppData\Local\Microsoft\Team Foundation\
<< Agent Folder >> \ _Work\
Windows Temp folder

I have changed the task id (GUID) and it seems resolving this issue. But this is not viable solution as I cannot issue new task id for already published extension.

Due to this reason I believe best option to resolve this issue is deleting cached data. Please let me know, Where does the Azure DevOps / TFS cache it’s extension data?

Thanks in Advance!

Is cleaning browser cache and increasing the version number in the task.json helpful? — Cece Dong - MSFT
I usually close all browsers or do a Ctrl-F5 before triggering a new build after a component change but it is still sometime on the old version for one or two build/release. After it downloads the new one. — Etienne
@CeceDong-MSFT , Thank you for your response. Sometimes it fixes the issue but some times not. Better if we have concrete solution for this. — Lalindu
@Lalindu Do you try Delete task -- Save definition -- add task again? Is it helpful? — Cece Dong - MSFT

Try to clean the browser cache, and check whether you have increase the version number in the task.json.

Also, try to Delete task -- Save definition -- add task again, which should help.
