I'm trying to get the id of the current user (the user executing the method) with Identity package. The context is a UserManager<ApplicationUser> (ApplicationUser is an IdentityUser).
var currentUserId = User.FindFirst(ClaimTypes.NameIdentifier).Value;
I add this to the list of claims when a user logs in. 'user' is the ApplicationUser from the DB.
new Claim(ClaimTypes.NameIdentifier, user.Id),
I also used this doc and added the following in Program.cs.
builder.Services.Configure<IdentityOptions>(options =>
options.ClaimsIdentity.UserIdClaimType = ClaimTypes.NameIdentifier);
However, I keep getting an "System.NullReferenceException: 'Object reference not set to an instance of an object.'" error.
The link also showed that I could get the current user as
var user = await userManager.GetUserAsync(User);
However, that just made the user null.
I'm using postman/swagger for debugging.
Here is the entire stack trace:
System.NullReferenceException: Object reference not set to an instance of an object.

I'm answering my own question.
I simply needed the [Authorize] attribute above the method.

This question already has answers here:
Array.Sum() results in an overflow
(5 answers)
Closed 6 months ago.
I've already tried some solutions that I found in other posts, but I'm still without success.
I have a list that I would like to add a value in a certain condition:
long teste = (long)joinHhResWithMemRes.Where(x => x.OcupacaoCode == 1).Sum(x => x.Weight);
but it always returns this error:
System.OverflowException: Arithmetic operation resulted in an overflow.

I've tested several types of variables, from long, ulong, double, decimal, but without success.
I exported the list to excel and did the manual calculation and the final value is: "46219134368", so long should be enough.
FYI the list has 2322 rows.
I appreciate your help.
You are still adding whatever type is x.Weight. Move the cast to inside the Sum:
long teste = joinHhResWithMemRes.Where(x => x.OcupacaoCode == 1).Sum(x => (long)x.Weight);

If I changed the database to UseInMemoryDatabase it works on Docker.
I have other API with MongoDb from Azure and works without problems on both sides.
Thanks in advance for the help.
Azure SQL requires encrpytion on all connection all the time.
Try adding the following settings to your connection string:
Encrypt=True;TrustServerCertificate=False;
I see the solution on other forum:
This post save my life: https://github.com/dotnet/SqlClient/issues/653
I use this solution and worked.
string ManagedNetworkingAppContextSwitch = "Switch.Microsoft.Data.SqlClient.UseManagedNetworkingOnWindows";
AppContext.SetSwitch(ManagedNetworkingAppContextSwitch, true);
This issue comes up in my server and I'm not able to catch where is it coming from, how can I track an issue like this and what might be the cause?
I have bugsnag setup in my server + newRelic and both don't give me information about this issue.
I'm running my application on a Ubuntu 18.04.5 using nginx.
Also is it normal that when this issue comes all the request on the server goes into Gateway timeout.

An unhandled exception has occurred while executing the request.```
Check out this issue on GitHub: https://github.com/dotnet/aspnetcore/issues/23949. Especially this comment:
This exception seems to be thrown when a client aborts mid-request.
You can ignore this error by including the following MVC exception filter:
if (ex is Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException &&
ex.Message == "Unexpected end of request content.")
{
// "Unexpected end of request content."
// Microsoft.AspNetCore.Server.Kestrel.Core.CoreStrings.BadRequest_UnexpectedEndOfRequestContent
// ignore this
}
I have an ASP.NET Core 3.1 MVC project, using Oracle.EntityFrameworkCore (tried all 3 latest version) to build code from an existing Oracle database.
EF Core provides the database first method to create models from the database tables.
In the Oracle database, the Book table has definition of
BOOK_ID NOT NULL NUMBER(10)
And EF Core created the field as int32
public int BookId { get; set; }
In the BooksController, GetBook method, there is this line:
var Book = await _context.Books.FindAsync(id);
When the id is small, for example, 5, it worked just fine. However when the id is big, for example, 412897, it will throw an error. The entire error stack trace by Postman is pasted below:

By searching online it seems to be the different definitions of integer by .net and Oracle. I found a solution to add HasConversion to OnModelCreating in DbContext class.
entity.Property(e => e.BookId)
.HasPrecision(10)
.ValueGeneratedNever()
.HasColumnName("Book_ID")
.HasConversion(t => Convert.ToInt32(t), t => Convert.ToInt32(t));
However it doesn't solve the problem. The error was as before.
Any suggestion is appreciated.
Thank you.
