I'm just trying to get started with this library and encounter the same problem. I see validation errors when various input fields lose focus but the form happily submits anyhow....

@michaelgsharp @IntegerMan I was able to reference Microsoft.ML 2.0.0-preview.22115.2 and Microsoft.ML.AutoML 0.20.0-preview.22115.2 using the source on Azure, but still encounter the same problem.

@michaelgsharp Any word on this?

@michaelgsharp I was already passing in bestRun.Model ```C# var bestModel = bestRun.Model; var permutationFeatureImportance = mlContext .Regression .PermutationFeatureImportance(bestRun.Model, testDataViewWithBestScore, permutationCount: 3); ```

@michaelgsharp No joy with 1.7.1. If it helps:  Let me know what other information might be helpful diagnosing this.

@michaelgsharp Sure. I changed the headers to obfuscate the domain. Not sure whether it matters, but I'm using cross-validation. [TheData.zip](https://github.com/dotnet/machinelearning/files/8337604/TheData.zip)

@michaelgsharp Still seeing the issue. I've attached a minimal reproducible example [MlMre.zip](https://github.com/dotnet/machinelearning/files/8375357/MlMre.zip) .

Same issue here. Hopefully it can be resolved soon. Great package, hate to lose people that can't get past this problem.
