ChangeConfigurationByName fails with "The specified configuration settings for Settings are invalid."

Question

Hello,
I am tryint to update deployment and always have following error
"The specified configuration settings for Settings are invalid. Verify that the service configuration file is a valid XML file, and that role instance counts are specified as positive integers."
Have found similar
thread  and
stack overflow - without any success. I am not chaning anyting. Just reading deployment configuration and tryint to update with the same settings. I use .net azure sdk  wrappers to generate requests. Code looks like:
var deployment = client.Deployments.GetByName(location.DataCenter, location.Cluster);var result = client.Deployments.ChangeConfigurationByName(location.DataCenter, location.Cluster, new DeploymentChangeConfigurationParameters{  Configuration = deployment.Configuration});
Catched request response from fiddler:

Hi,
The configuration file is a file with extension .cscfg. If you have Visual Studio, the file is automatically generated when you create the project, and automatically updated when you modify the project's properties.
  >> Not sure were could I get content of this file from api?
It's needed to encode this file's content use base64, and put the result in the body of your request. (Please refer to
http://msdn.microsoft.com/en-us/library/windowsazure/ee758710.aspx for more information.)

However, may I know how you find the body for your request? (It seems you do a base64 decoding, you find it is a valid configuration file, but it doesn't have any configuration settings.) Actually, the settings defined in csdef needed to
be contained in the configuration file.
