WAStorageEmulator no recognized

For our tests to run, we setup a database, IIS, and start the Azure storage emulator. Everything was working just fine on Friday, but now I get the following error everytime I try to build

'"C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator\WAStorageEmulator.exe"' is not recognized as an internal or external command, operable program or batch file.

Has anything changed over the weekend? I've tried rebuilding old builds from last week that were fine, but now they fail at this point too.

I have downloaded and installed the latest Azure SDK on my laptop and the executable is in the folder above. Any help to get this building again would be greatly appreciated.

    Hi Steve,

    There was Azure SDK 2.6 installed: http://www.appveyor.com/updates/2015/05/03

    That's weird it broke Azure Storage Emulator - I will take a look.

    I just installed the latest SDK on my laptop from the website


    I picked the VS2013 one as that's what I'm using. Only did it really to see if it installs the executable in a different folder, but I don't think it does.

    It looks like executable was renamed to AzureStorageEmulator.exe.

    Azure SDK 2.5 comes with Azure Storage Emulator v3.4 and there is C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator\WAStorageEmulator.exe while SDK 2.6 comes with Azure Storage Emulator v4.0 having only C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator\AzureStorageEmulator.exe

    That's weird nor storage emulator release notes nor Azure SDK notes do not state that in "breaking" changes:

    I've asked about this change in comments to this page and also submitted support ticket to Microsoft Azure.

    I guess this rename is part of bigger renaming campaign moving from "Windows Azure" to just "Azure" across all products. I think you should use AzureStorageEmulator.exe going forward. Alternatively, you may want to rename/copy both AzureStorageEmulator.exe and AzureStorageEmulator.exe.config to WAStorageEmulator.exe and WAStorageEmulator.exe.config respectively with a simple commands before tests.

    Let's keep this thread opened to help others.

    Got confirmation from Microsoft support that executable was renamed.

    Thank you very much Feodor. Strange that they didn't mention it as a breaking change in the release notes.
