@kus do you get an exception or empty data is returned?

Are plain `C` questions allowed here?

FoggyFinder

just use `.FirstOrDefaultAsync()`

FoggyFinder replying to kus

you don't have to know it to see the difference in "jit"

kus

I don't know how to read this :/

FoggyFinder replying to kus

yes

kus

is .Take(1).SingeOrDefaultAsync() different from .FirstOrDefaultAsync()?

added it (: https://github.com/myblazor/myblazorserver/commit/9b2bb3b870488f0315a0ca36fbe9f0921ab4d1ce

FoggyFinder

You could try to use [BlazorLiveReload](https://github.com/martasp/BlazorLiveReload) for now

FoggyFinder

confirmed: it is an expected behaviour

FoggyFinder

I'll try to clarify this moment

FoggyFinder replying to kus

I suppose you have to refresh page in a browser after each changes

kus

I can't get visual studio code to run with dotnet watch run because it seems to want --project but even if I use the terminal and cd into the project folder, it still gives me "Could not reconnect to the server. Reload the page to restore functionality." after every edit https://github.com/myblazor/myblazorserver

FoggyFinder

@kus ^^ I hope you will get a notification :-)

FoggyFinder replying to kus

Do you mean `watch` - mode ?

FoggyFinder

`Avalonia` tag is requested here as well

FoggyFinder

awesome

Jack Douglas replying to FoggyFinder

You can actually just hit the 'listen' link in the top right corner

Jack Douglas replying to kus

thanks :)

kus

I get that blazor server compiles *very* fast even on my crappy lappy but it is kind of tiresome to rebuild everytime I change something in the code :( maybe I've been spoiled by angular but is there a way to get blazor server to recompile on save at least in visual studio code?

how about posting that question @kus, I want to post my solution! ;)

Oh, I've missed an interesting conversation. Writing to get a notification for a next time:-)

```  
serviceData.Potato switch { true => "Yes", false => "No", _ => ""

Jack Douglas

I have a nice concise readable solution with 8.0

Jack Douglas replying to kus

Are you using C# 8?

kus replying to Jack Douglas

I was trying to write a question and realized I did it wrong  
  
    string potato= "";
    if (serviceData.Potato == true)
        {
            potato = "Yes";
        }
        if (serviceData.Potato == false)
        {
            potato = "No";
        }

Jack Douglas replying to kus

Can you post that as a proper question? I find it interesting…

kus

basically, all I need is the string to be "" if Potato is null, "Yes" if true, and "No" if false.

kus

  
                string potato= "";
                if (serviceData.Potato ?? false)
                {
                    potato = "Yes";
                }
                else
                {
                    if (serviceData.Potato ?? true == false)
                    {
                        potato = "No";
                    }
                }  
  
serviceData is an object. Potato is a bool? How can I make this more readable in C# .net core 2.1?
