Question

For some reason my DevStorage account has stopped working. I get a 400 Bad Request error on every request to DevStorage (both Blob and Table). I can browse DevS

Answer 1

Did you by any chance install the latest version of Storage Client library (3.0.0.0) which was released yesterday? That could be one reason why your code stopped working because the latest version of library doesn't work with storage emulator (Scroll down to the bottom of this post: http://blogs.msdn.com/b/windowsazurestorage/archive/2013/11/27/windows-azure-storage-release-introducing-cors-json-minute-metrics-and-more.aspx). If you look at the detailed error message, you will see One of the request headers is invalid.

UPDATE: 03-Feb-2014

Please download Storage Emulator 2.2.1 Preview which has support for latest storage client library. More information about this release can be found here: http://blogs.msdn.com/b/windowsazurestorage/archive/2014/01/27/windows-azure-storage-emulator-2-2-1-preview-release-with-support-for-2013-08-15-version.aspx.

UPDATE: 15-Apr-2014

If you're using SDK Version 2.3, then there's no need for installing Storage Emulator 2.2.1. Storage Emulator in version 2.3 fully supports Storage client library 3.x.

Answer 2

I had the same problem with Azure Storage Emulator 3.0.0 which came from Azure SDK 2.3 on VS 2013 update 2.

To solve the problem I started the Web Platform Installer and searched for Storage Emulator then ran the Azure SDK 2.3 (VS2013) and it installed Storage Emulator 3.2.0.0 which fixes the problem.
