So it's not a module, it puts Atom in window?

I don't think you can, but if your intent is for data annotations, would this help? You could source gen the metadata class : https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.dataannotations.metadatatypeattribute?view=net-6.0#examples

I figured that out that I didn't need to load the library as it will be already available for me to consume it

        public async Task<string> GetRevision()
        {
            return await JSRuntime.InvokeAsync<string>("Atom.GetCurrentThreeRevision");
        }

        public async Task<Scene> InitiateScene()
        {
            return await JSRuntime.InvokeAsync<Scene>("Atom.InitiateScene");
        }

How is everyones performance of VS doing after the last update? It seems to me that loading a solution takes more time. One of my solutions take more then 1 minute to load

SQL-MisterMagoo

@SQL-MisterMagoo

Ok, but I use the preview - there are quite a few settings for solution/project loading strategies in the preview - don't know if you have/can play with them in RTM?

Mario van Zeist

@MariovanZeist

I am going to try preview, see if that has a difference.

Or maybe I just need a new PC with more SSD's :)

Sorry for the stupid question but have you excluded dotnet and VS from your virus scanner real-time scanning?

... But not nugget folders obviously

Mario van Zeist

@MariovanZeist

Yeah they have been excluded.

Looking at Task Manager it doesn't seem that the Main VS instance is causing the problem, because it's at 0% CPU/Disk and Network usage

But I see a process called ServiceHub.ThreadedWaitDialog.exe that starts when I see VS hanging up, and as soon as it's closed, VS also continues again.

All the time no Disk and CPU activity

Mario van Zeist

@MariovanZeist

Tried Preview, same deal.

Load time is 95 seconds for one of my solutions :)

And disabled virus scanner for good measure... no change :(

MisterMagoo

That threaded wait dialog is supposed to show itself if the task takes a while. Do you have any VS extensions?

Mario van Zeist

@MariovanZeist

Hmmm good idea, yeah I have. lets disable some

Mario van Zeist

@MariovanZeist

@mistermagoo:matrix.org It looked promissing, but after disabling all extensions, It still takes 90 seconds..

Only the first time after I start VS

When I close solution and then reopen it again it's fast..

Going to have a look with Process Explorer

Hey guys, how do you enforce consistent code styling for Blazor projects? I cannot find any Roslyn analyzer designed to work Razor files

I've been writing code on https://jsfiddle.net/ for half an hour

I close it by mistake and its all gone....

Oh nevermind! There is a popup that puts back everything

@SparkyTD

Is there a way to expose or "cascade" a component variable to the ChildContents? So for example everything within the component's tags would have access to that variable, including embedded C# code.

Is there a way to get a Ref to a <DynamicComponent> which implements a base type, i.e public abstract SomeCompontentConvention : ComponentBase then in the actual razor file @inherits SomeComponentConvention?

i.e I want to be able to do @ref="ComponentInstance" then have public SomeComponentConvention ComponentInstance {get; set;} if that makes sense

Peter Morris

@mrpmorris

@zHaytam Try maths, it's like math, but more than 1

Haytam Zanid

@zHaytam

@grofit Did you try it and it didn't work?

Can anyone here help with this Entity Framework problem I'm having? https://stackoverflow.com/questions/73334229/the-property-child-parent-is-of-type-parent-which-is-not-supported-by-the-cu?noredirect=1#comment129508339_73334229

Peter Morris

@mrpmorris

I can see the same code working in another app :(

@grofit

Sorry was side tracked @zHaytam yes it doesnt work as it cant cast DynamicComponent to the type requested, the internet has no information on this really

I am working around it another way but thought I Would ask the question as I will be using DynamicComponents quite a bit

Haytam Zanid

@zHaytam

Oh, I understand now

Automatically I doubt you can do it

But you could do it using setparametersasync and the Instance

@mrpmorris

Well, a better worded error message could easily have saved me most of a day - dotnet/efcore#28695
