Using Azure Storage Emulator in IaaS apps

Check for local SQL Server instances by one of the below tools:

svrnetcn
SQLCMD –L
OSQL –L

Run Storage Emulator from command line:

c:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator>
c:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator>WAStorageEmulator init /forceCreate
c:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator>WAStorageEmulator.exe start

 

Verify the icon on the task bar:

Mouse over the icon should:

Right-Click on the icon:

Select Show Storage Emulator UI: (validation)

 

The port number and the other configuration can be found in C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator\WAStorageEmulator.exe.config

Telnet to Storage Emulator: (alternative validation)

c:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator>telnet localhost 10000

Type “^]” (without the quotes to exit)

netstat –natf –p tcp (alternative validation)
