.NET (Core and Framework)

I need a efficient , verbose and efficient analytical tool which I want to integrate in my application. The requirement or expectations are -



1. Online feedback.

2. Provide a more in-depth version of the quick start guide, with section headings acting as individual articles.

3. Product Tour for New Users.



Also to add my application is designed purely in .NET framework using MVC (may integrate to .NET core in future). So suggest something which is compatible to the technology stack as well.



Thanks

var Violations = UnitOfWork.ViolationRepository.GetAll()
                    .Include("NOV")
                    .Include("NOV.CitedPartyData")
                    .Where(i => i.InspectionItemId == inspectionItemId)
                    .OrderBy(i => i.ViolationId).ToList();
                return Violations;

Case _case = (from x in this.Context().CaseRepository.GetAll()
                              where (from g in x.Violations
                                     join a in this.Context().OneToManyRepository.GetAll().Where(a => a.ParentEntity == "Notice" && a.ChildEntity == "Violation") 
                                     on new { g.ViolationId, this.NOVId } equals new { a.ChildEntityId, a.ParentId }
                                     where g.CaseId == x.CaseId 
                                     select g).Count() > 0
                              select x).FirstOrDefault();

                this.TriggerMetaDataUpdate<Case>(_case);
                this.TriggerMetaDataUpdate<InspectionResult>(this.InspectionResult);
