The whole Model builder experience feels broken...

**System Information (please complete the following information):**
- Model Builder or CLI Version: Model Builder 17.15.0.2321402
- Visual Studio Version (if applicable):
- Visual Studio Professional 17.5.4+33530.505
- Visual Studio Community 17.5.4+33530.505

**Describe the bug**
Well, this Model Builder tool seems to be very poorly written or maintained, it has several issues. The most easiest to see if those you get by just running the Machine Learning Model and follow the steps outlined in the [getting started guide](https://dotnet.microsoft.com/en-us/learn/ml-dotnet/get-started-tutorial/intro).

The two most easiest to find is that the scenario page is missing the images. The second is that after the initial training I always get following error (I get this both when I run the getting started guide and other scenarios).

Missing images:

Error:

**Expected behavior**
Well, the model builder should work is at least what we can expect.
