Would u please provide an screen shot of that error? and let me know which version of .NET core is already installed in your machine and which version of OC are you using?

I suspect you need to publish as a self contained app.

I imagine you're publishing to Azure? Which does not yet (AFAIK) have the dotnet core 3 runtime, so you need to publish with the runtime.

If you are doing this from visual studio, you select publish as self contained

@overstartup If you've published your app as self-contained, There's file named Web.Config. If you're using .Net Core 2.2, few lines of web.config file are like photo below:

In this case remove V2 from modules="AspNetCoreModuleV2" and save the config file, then restart you app.
