Bug Fixes

  • A service exception thrown while processing a user request no longer results in a NullReferenceException.

Known Issues

Installation Requires Administrator Privileges The default install location is %PROGRAMFILES%, which on most computers is "c:\program files". In order to install files to the default location, the MSI must be run by an Administrator. If you don't have Administrator privileges on the machine, please change the install location to something like "c:\Documents and Settings\<you>\AWS SDK for .NET", and the install will complete successfully. If you are running on Vista, your personal folder is similar to "c:\users\<you>\".

See also the related known issue on installing the SDK in a custom folder.

Installing the SDK in a custom folder requires templates to re-add the AWS .NET library If you install the AWS SDK for .NET in a location other than the default, let's say "c:\users\sdktester\AWS SDK for .NET", the built-in project templates and samples fail to compile due to a missing reference. Please update the References section of your Visual Studio solution as follows:
  1. Remove the existing AWSSDK reference.
  2. Right-click on References and select Add a Reference.
  3. Browse to the new install location's bin folder (c:\users\sdktester\AWS SDK for .NET\bin).
  4. Select the AWSSDK.dll from within the folder.
  5. Compile -> Run -> Explore AWS.
Uninstalling the SDK produces "Unknown Publisher" message On Windows Vista, uninstalling the MSI results in an "Unknown Publisher" dialog even though the installer is signed by Amazon Web Services. This is a known Windows Installer bug on Windows Vista, and is documented here:
