AvaTax C# SDK Upgrade

AvaTax C# SDK Upgrade

Avalara was advised of an issue affecting some users of the AvaTax C# SDK. In some environments, the C# SDK submitted HTTP verbs in lowercase, which is not always permitted by firewall and router rules. Avalara is publishing a revision of the C# SDK to correct this issue. We advise all customers using the C# SDK to upgrade to the latest revision.

Does This Affect Me?

Customers known to be affected are running the combination of:

  1. Visual Studio 2017
  2. on Mac OS X
  3. with AvaTax C# SDK or earlier

Our testing team has evaluated this issue, and will continue to test in a variety of environments and C# versions. As of this date we are not aware of any other versions that are affected. Whether or not you are affected by this issue, we encourage you to periodically update your NuGet reference and download the latest revision of AvaTax from NuGet.

How To Update the AvaTax C# SDK

You may update your C# SDK version by following these steps:

  1. Open your project that uses the AvaTax C# SDK
  2. Update NuGet Packages
    In the Solution Explorer, open the context menu for your solution. Select “Update NuGet Packages.”  
    Or open the dependencies for your project in the Solution Explorer.
  3. Right-click on Avalara.AvaTax and select “Update.”
  4. NuGet will update your SDK to the version
  5. Your version of the AvaTax C# SDK is updated and you are good to go!
