I'll go ahead and try these things right away. I solved my app.manifest issues by ticking the 'NET Desktop Development' profile in the VS 2019 installer!

Hi I have an Entity as below:
public class Complaint
{
public Complaint()
{ }
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
[Index("IX_UniqueConstraintComplaint", 1, IsUnique = true)]
public int? InspectionRequestId { get; set; }
public InspectionRequest InspectionRequest { get; set; }
[Index("IX_UniqueConstraintComplaint", 2, IsUnique = true)]
public int? InspectionResultId { get; set; }
public InspectionResult InspectionResult { get; set; }

public int? CaseId { get; set; }
public Case Case { get; set; }
[Index("IX_UniqueConstraintComplaint", 4, IsUnique = true)]
public string ComplaintId { get; set; }
}
I want to rename this entity as below with couple of column names changed, can somebody please help me in this
public class RequestResultCaseComplaint
{
public RequestResultCaseComplaint()
{ }
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int RequestResultCaseComplaintId { get; set; }
[Index("IX_UniqueConstraintComplaint", 1, IsUnique = true)]
public int? InspectionRequestId { get; set; }
public InspectionRequest InspectionRequest { get; set; }
[Index("IX_UniqueConstraintComplaint", 2, IsUnique = true)]
public int? InspectionResultId { get; set; }
public InspectionResult InspectionResult { get; set; }
[Index("IX_UniqueConstraintComplaint", 3, IsUnique = true)]
public int? CaseId { get; set; }
public Case Case { get; set; }
[Index("IX_UniqueConstraintComplaint", 4, IsUnique = true)]
[Required]
[StringLength(20)]
public string ComplaintId { get; set; }
}
I previously had the entity as in the 2nd case, unfortunately I removed it, and now when I am trying to create with same name again, whether EF has cached it I don't know, but EF is not recognizing it, can somebody please help me in this, does EF cache the already created Entities with same names, how can we clean it?
Its not allowing me to create the same Entity again even after deleting the Entity and trying regenerate again.
Or at least can I rename already existing Entity and its columns, how can I do it any help please?

If you're still in development, and using Code First, then just nuke the database / tables.

Funny - I don't have nuke weapons  ,
I did achieve it, I manually wrote up and down methods and ran them against, challenging, scary but did it, thank you both for the help buddies.

Hi,
We are working on a project, where there are 2 different web applications are used by the same user. Hence we need Single Signon (SSO), so that when a user is logged in one application opens the second application, it should not ask for relogin, if the user have permissions.
Our web application is on .net core 3.1
We had implemented SSO using identity 4. we had refereed a sample application (.net core 2.0 and identity 4 server 2.0) and implemented the same.
Issues facing
1. Even if a user have permissions for both the applications and logged in to 1 application, when he tries to open the 2nd application, it asks to signin again(ie, it is not authorized)
2. For admin user, which have all the permission, it fails to open the application due to cookie memory issue.
We have tried to upgrade the identity 4 server to the latest (4.1), but it through run time error.
Please help to resolve the issue.

If you're talking about IdentityServer[^], you're best source of information is going to be the people that wrote it. There's a "Contact" link in the upper right corner of the site.

Hi,
I am building desktop application using .net framework. Front end will be deployed in client PC and database will be kept in LAN server. In this case which is best database to be used.
Since I am new to client-server implementation how to make sure connection string while installing front end in client PC and is there any instance of database needs to installed before establishing connectivity. I don't want to too much dependencies while installation since client is startup company and not able to invest on licence databases.
Regards,
Rahul

You could use SQL Server Express, or google for free\open source database solutions, but using SQL Express would make it easier to go to proper SQL Server when they can afford it. However I would strongly question any company, start-up or not, that can't afford to properly license software and I'd also be wary working for such a company.

What SiteCore said - SQL Express will give you 4gb of storage and limited connections but will allow you to easily upgrade to a licenced version when you outgrow the express.
I do hope you are doing this pro bono or as a training/entry exercise, it does sound dodgy.

I see some articles on migrating away from .NET remoting, but so far I haven't found anything that flat out says I shouldn't use it for new projects.
Does anyone know the state of the world regarding .NET remoting in say... DNF 4.72?
I have no requirements to support Core because my project involves a window service that does interprocess communication. I want to use .NET remoting for that. It's not internet facing, it's purely for IPC.

It doesn't seem to be explicitly obsolete, but it's definitely a legacy technology, and not meant for new projects.
.NET Remoting is a legacy product that is supported only for backward compatibility. ... We recommend existing Remoting applications be migrated to newer and more secure technologies.
.NET Remoting was identified as a problematic architecture. It's used for cross-AppDomain communication, which is no longer supported. Also, Remoting requires runtime support, which is expensive to maintain. For these reasons, .NET Remoting isn't supported on .NET Core, and we don't plan on adding support for it in the future.
It looks like Remoting won't be ported to .NET 5 either.

And in addition to the above question:
(1) Is WCF deprecated? (I thought it was deprecated but perhaps I'm wrong).
(2) What is the latest recommended relatively high speed inter-process communication standard?

I'm implementing asp.net core 3.1 project. In my controller I have a linq query like the following and without defining inprocessapicount and pendingcount which claculates counts of related amounts, it works fine but after adding them to my query in select part, applicants returns null. I appreciate if anyone suggests me a solution.
var applicants = (from t1 in _context.VwDesk
{
apiID = t1.ApiId,
applicantID = t1.ApplicantId,
applicantName = t1.ApplicantName,
gateName =t1.GateName,
requestStatus = t1.LastReqStatus
}
group tg by new { tg.requestStatus,tg.apiID ,tg.applicantID, tg.applicantName} into ApiAppGp
select new
{
applicantName = ApiAppGp.Key.applicantName,
apiname = ApiAppGp.Key.apiID,
apicount =ApiAppGp.Count(),
inprocessapicount = ApiAppGp.Where(a => a.requestStatus == "bb").Count(),
pendingapicount = ApiAppGp.Where(a => a.requestStatus == "aa").Count()
}).ToList();

Query's too "complicated" for anyone to bother with. Need to break it down with intermediate queries and results that you can "debug". "Big" queries are a sign of laziness; not sophistication. LINQ is no smarter than the person wielding it.

I think I finally understand OAuth/OIDC/IdentityServer/IdMgr/IUA/ASP.NET Identity well enough to recognize the answer to my question.
Can anyone point me at a full featured end user self registration example/add-on for IdentityServer 3 or 4?
I'm aware of the admin UI ad-ons. I'm looking for an end-user oriented features that allows end-users to register themselves, including contact info and administer their contact info once registered.
I'd like functionality similar to Individual User Accounts in MVC projects. I'd also like the functionality, including UI, to reside on the STS and integrate with the STS OIDC authorization functionality.
A user registration add-on for IdentityServer 3 or 4 would make my day.
Or, is it true that comprehensive turn-key user registration for IdentityServer does not exist?
I have reviewed and ran the IdSvr3 AspNetIdentity integration samples. If end user self registration is there I don't see it.
I have seen a few examples that showed how to add a user registration page to identity server but they seemed more like a hack than comprehensive user self registration/contact info admin feature, ALA MVC Individual User Accounts.
Using IdentityServer4 hosted in a .NET Core web app as the STS is an option I've explored. I didn't find any complete examples there either.
