This is the warning message
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.'.
Any kind of help is appreciated. Thank you
Check this https://github.com/dotnet/aspnetcore/issues/14723
Disable analyzer in Project file for testing purpose only.
<PropertyGroup> <DisableImplicitAspNetCoreAnalyzers>true</DisableImplicitAspNetCoreAnalyzers>
</PropertyGroup>
After disabling this, check if you can still build the project.Check if any install package have prior version dependency.
I have been accessing
Microsoft.AspNetCore.MVC
package to access HttpContextAccessor and that causes the WARNING.
I solved this by reinstalling dependency/reference for HttpContextAccesstor and it lands me to this package
Microsoft.AspNetCore.Http.Abstractions
SOLVED
