The Home repository is the starting point for people to learn about ASP.NET Core.

Thanks. Will give this a try though we use blazor.

that's not what i said

Could anyone familiar with EFCore give me a hint as to what I am doing wrong? (I think it must be some stupid mistake).

Table units is existing Postgres table and has string id field as primary key. EFCore (5.0.0) is throwing an exception because it is looking for u.UnitId / u.unit_id (if using the UseSnakeCaseNamingConvention plugin) column despite the Column annotation and the fluent HasColumnName API call. Based on what I have read in the docs this should be working. Like I said, I think I must be missing something. Googling about lead to some suggestions of using fluent HasField instead but I am not sure that is what I want (Trying it results in an error saying it cannot find an id field so not sure what is going on there).

Gist with code: https://gist.github.com/rurounijones/c4adc0b90d4cf47fb3bc480af814a989

@_openTag
@* content *@
@_closeTag

@code {
  private MarkupString _openTag;
  private MarkupString _closeTag;
}

@andrewleith An option would be this primitive component, where you can pass whatever html element you want through the HtmlTag property

public class Element:ComponentBase
    {
        [Parameter] public RenderFragment ChildContent { get; set; }
                                  public Dictionary<string, object> UserAttributes { get; set; } = new Dictionary<string, object>();

       protected  override void BuildRenderTree(RenderTreeBuilder builder)
        {
            base.BuildRenderTree(builder);
            builder.OpenElement(0, HtmlTag);
            builder.AddMultipleAttributes(1, UserAttributes);
            builder.AddContent(2, ChildContent);
            builder.CloseElement();
        }
    }

So you can use it like

<Element HtmlTag="div" class="my-class" > <div> Child Content</div> </Element>

<div class="my-class"> <div> Child Content</div> </div>

my signalr hub gives 403 when I try to access wss://myurl.com/hub but it works well when I use https://myurl.com/hub
anyone here can help or just explain why this is happening ?

there is no Authorize attribute on my Hub so there is not authentication on hub url.
