Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
My team has developed a Blazor web app in .net 7. Due to our web servers requirements the entire App had to be upgraded to .net 8. Now, the app gets to the 100 in a circle view but never loads the content. When looking in the console found the following message.
Error: Failed to start platform. Reason: TypeError: Cannot read properties of undefined (reading 'AspNetCore')
I have tried to clear the cached in visual studio and in the browser, that didn't help
