How to downgrade maui sdk from 7.0.58 to 7.0.52

[juwens]

Description

We have several issues with the 7.0.58 and want to go back to 7.0.52. For example #11579 but also things like this C:\Program Files\dotnet\sdk\7.0.102\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1147: To build this project, the following workloads must be installed: ios [D:\gitlab\builds\QFfMLjaN\0\Foo\Bar\Baz.csproj::TargetFramework=net7.0-ios] despite ios and maui-ios is already installed with maui-workload of VS.
Depending on when people installed there VS, some colleagues/build-servers have 7.0.52, others have 7.0.58.
Dotnet workload provides no obvious way to downgrade.
What is your suggested way to downgrade the installed maui-sdk from 7.0.58 to 7.0.52.

We are on .net sdk 7.0.102.

Jesus, can you (the project team, not you personally) please stop playing the pingpong (report in VS) thing, i'm so tired of this attitude. Take responsibility for the maui issues, and don't frustrate customers even more. No it's not a VS issue. This is a maui architectural design issue and the way YOU choose to distribute it with dotnet workload!

So instead of saying "report to VS", can you (for the love of god) PLEASE provide the developers out there with a way, on how to downgrade maui-sdk (which is handled by dotnet workload, not VS!!).

sudo dotnet workload update --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/7.0.52.json
worked for me on mac, but didn't work on Windows (still installs 7.0.58).

For mac it's even worse because it asks you to upgrade to xcode 14.2 which isn't even supported by Visual Studio for Mac so basically you have a broken environment without an obvious way to roll-back...

@mattleibow - can you confirm that this issue should move to VS Feedback?

[FM1973]

Reading stuff like this will stop me from updating visual studio....
Please change the way we can update .net maui. Nuget seems to be a lot better for all of us.
So anyone can decide which version of maui to use...

[LennoxP90]

put this in your .csproj

<!-- Pin the MAUI version -->
<MauiVersion>7.0.52</MauiVersion>

@Hooterr thanks for the suggestion.

I tried that previously and just again now after you suggested it, sadly it seems, it doesn't do any significant change.

dotnet workload list lists 7.0.58, as before.
Maybe i am misinterpreting the output of the tool 🤔 Does it only show the latest version of installed SDKs?
Because, if i do dir 'C:\Program Files\dotnet\packs\Microsoft.Maui.Sdk\', 7.0.52 & 7.0.58 are installed.

@LennoxP90

put this in your .csproj

<!-- Pin the MAUI version -->
<MauiVersion>7.0.52</MauiVersion>

How sure are you, that this suggestion works?

Please do not use MauiVersion property going forward, it is no longer supported.

nothing broke haha, I guess you can never know but in all honesty there should be a way to pin the version outside of Visual studio that can be directly sourced with the application, just blanketly saying don't use x feature without an alternative is pure insanity

There definitely should be a way to pin a version, like with nugets.

I'm really eager to get to the bottom of this MauiVersion thing, but apparently with .Net 7 "MauiVersion" does nothing. At least i cannot find any code in the Maui-Repo with this phrase.

if it is used, it should appear be at least in some files (props, targets, cs, ...), right? Like it did in the .Net 6 times.

[LennoxP90]

@Redth, is there a reason MauiVersion was removed? is there alternative we should be using?

[Hooterr]

I tried that previously and just again now after you suggested it, sadly it seems, it doesn't do any significant change.

Didn't work for me on Windows either, but worked on my Mac. Go figure.

I remember during the recent MAUI standup someone from MS said that the thing with workloads is that they're 'Trying to build a bus while driving it' , which probably means we'll all end up in a ditch by the side of the road, wheels up lol
(don't ban me, please, I'm just trying to bring attention to the issue)
