Breaking changes for Windows Azure Media Services .NET SDK GA
On Dec 14th 2012, we update our .NET SDK to 2.0.1.0 and you could download the latest SDK here. And starting from yesterday (Jan 14th, 2013), we drop the support for older version of .NET SDK, which we released in Preview. In another word, our server no longer recognizes some of your old APIs. If you find your older version of .NET SDK no longer works, don’t panic! Please read through this blog and see whether you could fix the code.
If you still can’t find a clue, please bring your question to Windows Azure Media Services Forum and we will try our best to help you. Read more here
