Is your feature request related to a problem? Please describe.
Using Core 2.1 project with a 3.1 project triggers the following warning
Warning AD0001 Analyzer 'Microsoft.AspNetCore.Mvc.Analyzers.TopLevelParameterNameAnalyzer' threw an exception of type 'System.NullReferenceException' with message 'Object reference not set to an instance of an object.'.
I tried to install FxCop analyzers and Microsoft Analyzers nugets, but seems it's kind of a normal behavior that Microsoft won't fix. It happens when 2.x and 3.x are used in same project.
Describe the solution you'd like
Upgrade every projects in solution to Core 3.1 and republish a newer Nuget version for Core 3.1
Describe alternatives you've considered
I tried to upgrade the projects myself but could not transform the tests - ModelAttributes is deprecated in 3.1 and could not find a workaround or a rewrite strategy.
Additional context
No more request that this on. Your project is really great! I'm using it in french for validation errors and also for models resources in /Resources. Thank you!
