Function ({name}) Error: The binding type(s) ‘{triggerType}’ are not registered.

By Benjamin Perkins · · ,

I was working with an Azure Function V2 (beta) and got this exception, Figure 1, when I opened the Function in the portal.

Error:
Function (BlobTrigger-v2) Error: The binding type(s) ‘blobTrigger’ are not registered.
Please ensure the type is correct and the binding extension is installed.

The message triggered a recollection of when I created the trigger and remembered that a step was to install the Windows.Azure.WebJobs.Storage extension.  So I started the process to create a new, in this case, a Blob trigger and was prompted first thing to install the extension, Figure 2.

Once the installation completed, I stopped the creation of the new trigger and opened the one which was giving me the exception and the issue was gone.
