I upgraded a site from 9.13.2 to 9.13.11, and now the site throws FileNotFoundException errors for Avalara.AvaTax.netstandard20.dll on any product page. I enabled Assembly binding logging/Fusion Logging, and the log explained the error a little bit more. The full error log can be seen below:
Based on the error above, Dynamicweb.Ecommerce.TaxProviders.AvalaraTaxProvider.dll is calling Avalara.AvaTax.netstandard20.dll but that file isn't found. I don't see Avalara.AvaTax.netstandard20 in the site's bin folder, in the 9.13.11 bin folder, or in any previous version's bin folders.
This site was working without issue on 9.13.2, and only started having this problem when I upgraded to 9.13.11. We do still have another version of the site on 9.13.2 for comparison. That site is devupgrade-boca.mydwsite1.com.
Can someone look into a fix for this, or point me in a direction to fix it?
To get the site working for now, I disabled the Avalara tax provider on the backend in Settings->Ecommerce->Product catalog->Taxes->Avalara tax provider.
