i was confused with the @{} i guess
can't tell for blazor specific life cycle
Arnas Kučinskas
@Arnas-Kucinskas
It is on server side. Blazor was just an example, on how it works there.
So from this I gather that it is not going to happen on server side?

yes, all cs runs before any js in .cshtml

Does Razor Pages' partial views have support for an equivalent to Blazor's renderfragments in child components?

Hello, I'm trying build an old .net 4.5 mvc app on ubuntu and I can't seem to figure out how to get the 4.5 framework. Can anyone help me?
TeBeCo
@tebeco
you can't get the framework there
it's windows only
the only thing you can do is to reference nuget packages named Reference Assemblies
and that will let me build
but no test to run
there's no runtime for netfx on linux
only dotnet core
Raif Harik
@reharik
ug, so there's no way to work on this application?
TeBeCo
@tebeco
you can "build" only
there's also Mono but i'm not sure you can have it out of the box compliant
Raif Harik
@reharik
oh, so I can build but I can not run the app and access it in the browser?
TeBeCo
@tebeco
exactly
reference assembly are empty dll
Raif Harik
@reharik
so with mono, what do you mean out of the box compliant?
TeBeCo
@tebeco
it gives you something to compile against
because like dotnet core mono runs on linux
and i have no clue if you can make an app use mono as a runtime when you target netfx and do no code vu ange
Raif Harik
@reharik
so is there any work around so I can run the app and see if it works?
maybe, can you run windows in a container?
TeBeCo
@tebeco
anyway today mono is not integrated in the runtime
net4.5 was in 2010
migrate the app is advise number 1
Raif Harik
@reharik
uggg, it's old and all the damn nuget packages ancient!
how about can you run windows in docker container
TeBeCo
@tebeco
you meant in windows container
not i docker container

Can anyone point me in a direction to why this gives the error "no overload for method 'SingleOrDefault' takes two arguments)"? (The db is of ApplicationDbContext)
public async Task<User> FindByNameAsync(string normalizedUserName, CancellationToken cancellationToken)
{
return await db.Users
.AsAsyncEnumerable()
}
TeBeCo
@tebeco
count your ( and )
not spoiling the answer too fast
error telling you you gave sinfleordefault 2 args
and that it does not exists
meaning you have a syntax error
meaning it detected an , between first and second while it should have stopped there
so missing )

Can someone confirm if it the same behaviour from their end?

Remove cancellationToken.

return await db.Users
.AsAsyncEnumerable()
.SingleOrDefault(p => p.UserName.Equals(normalizedUserName, StringComparison.OrdinalIgnoreCase));

i need some info about a software.

this is the link below:

i want to know is it possible to make this kind of software using c# .Net.
if it's possible then can you guide me how should i approach to built this software.

i'm very interested to build this application as from this software experience i'm sure that i'm going to learn a whole new things and experience.
So, please guide me if you could.

Requirements:
i need two main features in my application:
1- get all teeth size data of upper and lower jaw by scanning. this is the camera i'll use ==> https://www.ximea.com/usb3-vision-camera
2- generate 3d model of upper and lower jaw teeth depending on step-1 data.

Note: if any tooth is missing then software will be able to reconstruct it during the 3d model.

that's all.

Queries:
i want to know which tools, languages other than .net,and technologies or SDKs will be needed in this project.
i've heard python will be good for getting data by scanning but after that what should i do in next step.
there are so many info i've searched on internet but those infos making me more confused because i don't know what exactly i need to do in this application. there are CAD/CAM SDKs option but don't know which one is right for me and compatible with .net.

I would really appreciate the help.

I'm trying to keep a connection alive and periodically send content through the connection with context.writeAsync to implement SSE. I could have sworn this worked before, but returning to it, as soon as I want to write more, writeAsync throws an exception: IFeatureCollection has been disposed. Object name: 'Collection'.
What has been prematurely disposed here, and how can I avoid that?

the part of the stacktrace where it apparently goes south is
   at Microsoft.AspNetCore.Http.Features.FeatureReferences1.Fetch[TFeature](TFeature& cached, Func2 factory)
at Microsoft.AspNetCore.Http.DefaultHttpResponse.get_HasStarted()
at Microsoft.AspNetCore.Http.HttpResponseWritingExtensions.WriteAsync(HttpResponse response, String text, Encoding encoding, CancellationToken cancellationToken)

Hi.
I'm trying to deploy a site using MSDeploy, but I'm having an issue when the files/folders are being added

Info: Adding file (DashboardTesting\Client\assets\).
Error: (2021/07/07 09:33:26) An error occurred when the request was processed on the remote computer.
Error: An error was encountered when processing operation 'Create File' on 'C:\inetpub\wwwroot\DashboardTesting\Client\assets\'.
Error: The error code was 0x8007007B.
Error: The path 'C:\inetpub\wwwroot\DashboardTesting\Client\assets\' is not valid.

at Microsoft.Web.Deployment.FilePathProviderBase.Add(DeploymentObject source, Boolean whatIf)
Error count: 1.

I'm not sure why it's specifying that the asset folder is a file, but it should create it as a directory.
Does anyone know where I can start looking?

Hi,

Under NET6 preview 5:

In startup, I register a singleton service:

services.AddSingleton(c => new MyService());

I have a line that injects this service in a razor file:

@inject MyService service;

When I run the project under VS (debug) all is good.

But when I run the same project as dotnet watch run, the IOC container complains that it cannot resolve the service inside the razor file:

InvalidOperationException: No service for type 'Project.MyService' has been registered

What could cause this difference and error in the first place under dotnet watch run` ?
