Hi @nikmes, @ASKemp,

Could you please paste the output window from the web server?:

I am having the same issue. It's probably related to several entries like this:

CoreUI.Mvc> The specified framework 'Microsoft.AspNetCore.App', version '2.1.0-preview2-final' was not found.
I believe I have a newer version installed.

Once I changed the following lines in the .csproj file from 2.1.0-preview2-final to what was shown below, it ran just fine.
PackageReference Include="Microsoft.AspNetCore.App" Version="2.1"
PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1"

Hi @Tharkis, good to know, I'll fix it in the repo/article.

It looks like the app was expecting to find 2.1.0-preview2-final in the system which was probably not what you all had installed in your systems.

I've seen this kind of issue somewhere else and, according to this: https://stackoverflow.com/questions/50928947/netcore-2-1-1-release-leads-to-app-failing-to-run, the best way to handle this is to remove the version altogether, as the runtime now will infer the version from the TargetFramework tag in the .csproj file.
