Azure Storage Emulator fail to start

Question

I'm trying to run Azure Function locally using Visual Studio and doing timed trigger, and I have set this in local.settings.json

"AzureWebJobsStorage": "UseDevelopmentStorage=true",

But when I run it, it has an error "Invalid storage account 'devstoreaccount1'.

I try to start the emulator (admin, turned off firewall), it has this error. Default install, no modifications.

Answer 1

After many tries, I managed to find out why. The default 10000 port is taken by a background process. I followed this instruction to find out which process and killed it, then it will work.

I have this same issue, how i solved that issue is given below

1. open command prombt as admin and change directory to C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator
2. Run command "AzureStorageEmulator.exe start -inprocess "

This worked for me

Answer 3

In my case I had spun up the newer Azurite storage emulator, which used the same port number.

Terminating that storage emulator allowed me to start the (deprecated) Windows Azure Storage emulator.
