I purchased license from getbootstrap.com. Can I download blazor sample?
If you purchased off of themes.getbootstrap.com website, you download the standard "HTML" version and unzip it. There is a folder called "backend-starter-kits" in the unzipped files. Open that folder. There is a file called downloads.html. If you open that file with a browser, it opens a Google drive folder with one zipped archive. Right-click on that archive and at the bottom of the options is to download the file. All the backend examples are in that archive.
Sorry, I meant to also add, my experience is from having purchased the "Good" theme. Not sure about the others.
