The application seems to works fine. Same issue with the Pro version also.

Update - I think this is normal behavior, as it is reported also by generic angular project, generated with dotnet CLI dotnet new angular -o my-new-app In angular.json file, property progress exists, which is turned to false in my-new-app. After turning it to true, it starts showing errors in console:

So I think this is normal behavior. If it bothers you, you can set it to false, and errors wont be shown. Can anyone confirm if this is correct?

I had the same problem, when running dotnet run I got lots of errors like the followings:

fail: Microsoft.AspNetCore.SpaServices[0]
      Compiling @angular/core : module as esm5
...
fail: Microsoft.AspNetCore.SpaServices[0]
      <s> [webpack.Progress] 10% building 1/1 modules 0 active

Despite the errors everything worked fine when running the web app.

ng serve did not show any error.

The errors disappeared after removing "progress": true, from angular.json like suggested by @JernejHabjan.

I don’t think this behavior is “normal”: the word FAIL seems to indicates something is wrong on the .NET Core side.
