Some notes for exporting PDF
To make it work, you have to copy native library to root folder of the SimplCommerce.WebHost. You can find latest version of native library here. Select appropriate library for your OS (libwkhtmltox.dll for Windows, libwkhtmltox.so for Linux and libwkhtmltox.dylib for Mac) and platform (64 or 32 bit).
When published, this navive library need to be inlcuded at the root folder.
Note, When running in IIS Express, the app cannot load the libwkhtmltox. Haven't figured out why.
