I want to use Blazor "desktop" to make a cross-platform UI (no hybrid, just Blazor). The UI should also run on Linux, correct? If so, what is the workload to use?
Alberto Passalacqua
@AlbertoPa
uhm apparently not possible https://github.com/dotnet/maui/discussions/1521

Well, for starters, Linux isn’t a supported platform for MAUI

does anybody made .Net 6 Preview 6 MAUI Blazor Template working (just plain project, then hit F5 and run)? Preview 5 worked well, preview 6 does not start (WinUI Project not startable, publish file not startable. Edge Web View 2 installed)

@AlbertoPa try checking out the https://github.com/ultralight-ux/Ultralight library. I think i saw someone host a blazor environment on it
i'd love for this functionality to be native in .net, though
but its just not ready yet

Funny, i could never got it to work in Preview 5 but it works for me in Preview 6. You are using VS 2022, right?

I think this is a different issue from @PatrizioR , does anyone know how to run a blazor maui app from the publish folder? I've tried double clicking the .exe and nothing happens. I can get the app to run from VS using the debug button or F5..
Alberto Passalacqua
@AlbertoPa
@chucker23n:matrix.org the messaging has been unclear to me. When they announced MAUI, Linux was out. However, later the message has been that Blazor apps will be able to run on Win/Mac/Lin, and the same is discussed in two issues (with Linux support now moved out of Net 6). The lack of support for Linux has been a headache, and really, even they have several apps that do not use their tech because they need to really be cross-platform, so credibility-wise, it does not look great.

@makotech222 thanks, I'll take a look :-)

Hi All. I'm doing some source gen on a view model and at a certain point want to place all of an object's properties into an Excel file. This is going OK, however I've generated a List<string> to pass the values to a function that uses EPPlus to build the spreadsheet. The biggest issue is that dates get formatted as text and so don't benefit from the user's culture (they're always "mm/dd/yyyy"). This is clumsy. How do a build a List of primitives instead, so I can ensure correct cell by cell population?
Or should I alternatively build a list of Tuple<Type, object> from sourcegen?
Sören Nils Kuklau
@chucker23n:matrix.org
[m]
Does the type help you?
If not, just pass objects
Simon Ziegler
@simonziegler:matrix.org
[m]
I need to know the type in order to enter the data in the correct manner. Dates in particular need to be Excel-ized.
Sören Nils Kuklau
@chucker23n:matrix.org
[m]
You could make a generic method where you switch on the type. But while I haven’t tried EPPlus myself, it seems you’d just set the Value property either way

If you pass date as yyyy-mm-dd, doesnt excel convert to date?

Would code with Parallel.For run (even though not in parallel) in Blazor WASM? :-?
Ivan Josipovic
@IvanJosipovic
I think i read they fixed parallel for in wasm
dotnet/runtime#43411

whoever did that has all my love :-)
in 6... ok, so not yet
Alberto Passalacqua
@AlbertoPa
would come handy to reuse some math libs :)
Alberto Passalacqua
@AlbertoPa
actually, it works in 5 too
Sören Nils Kuklau

Heh. They seem to be arguing over whether it’s fixed

You can always try/catch PNSE.

Sören Nils Kuklau

Not technically wrong!
Peter Morris
@mrpmorris
@simonziegler:matrix.org You can durst cells in excel. If that works then it is recognising it as a date. In which case you need to find out how to format a column, not the values
Peter Morris
@mrpmorris
durst = format (silly phone)

@AlbertoPa re: Parallel.For - if it's your code, then yes, as long as you configure it to never use more threads than are available - I have it in some code that I run in SSB and WASM, so in WASM it only uses the 1 thread available and is slower, but at least it does not break.

If it is a library that didn't think about limiting threads then not likely to work.

Hello folks, I have a tiny problem with the Navigation Manager. I am currently trying to show a dialog based on location change. That part works ok, except that, when I click the first component in the side menu, the navigation happens first, and then the dialog shows. When I do the same but click on the second component in the side menu I get the desired functionality, the dialog pops,and then based on the choice I navigate to another page, has someone had simmiliar problems like this?
Mario van Zeist
@MariovanZeist
@ItsIgzy_twitter The NavigationManager.LocationChanged event will always happen after the Location has been changed. Can you elaborate on what your desired functionality is? e.g. showing a dialog after navigation, or show a dialog before navigation, and redirect user to another page?

Whoah! This is a PG rated repo.

All, I'm running my app on .net 6 preview 6. How do I revert back to preview 5?

I want to show a dialog when the user clicks on a navmenu item, displaying a warning, and informing the user that he is going to navigate to another page, and offer him options to stay on the current page or navigate to another page.

Example would be:"User is on a details page, he then clicks on navmenu home, before the navigation starts, a dialog should pop and tell the user that he is leaving the current site and will be navigated to home, or what ever page he choosed from the nav menu"

I want to change both. Changing the package refs is straightforward, how do I do the SDK?

Anyone else have an issue/annoyance with double quotes in the razor editor? For example inserting double quotes always inserts a set of 2.

you need to wrap in ()
and also, the Razor editor is a mess :)

yes

@ItsIgzy_twitter As long as you don't want to abort that navigation it's ok, as there is currently no way to abort a Navigationevent in Blazor. But keep in mind that the LocationChanged event is called AFTER navigation has already occurred.

which basically tells me that I don't have any more options :D thanks I saw your PR on github, and if I may ask is there a way through JSRuntime to achieve that?

You can add a warning when a user attempts to close a tab or window in JS using onbeforeunload, but I don't think JS can intercept navigation done by Blazor
