If you are using RequiredAttribute from Microsoft.Build.Framework in the model you are trying to bind, you will get this error. Verified with the latest (stable) nuget. Remove the attribute OR use the attribute with the same name from System.ComponentModel.DataAnnotations. This is a typical “resharper alt+enter” bug 😃
