Unable to build a project with net7 RC 1
Description
Upgraded to newest VS Preview with support for maui .net 7 RC 1, but I´m unable to build the project. The output complains that workloads for IOS and MacCatalyst are missing. I repaired both, .net 7 RC1 SDK and VS but it had no effect.
Output of dotnet workload list:

+1 for this - I also have the same issue.
I also tried completely removing Visual Studio 2022 Preview and doing a fresh install. Doing this resulted in losing all of the MAUI + Blazor Hybrid project templates from the "File -> New Project" dialog. And yes - I do have the MAUI workload installed in the Visual Studio installer.
It appears that the required workloads are not installed when you download visual studio. Additionally, they cannot be found on nuget when attempting to use dotnet workload restore.
Steps to reproduce would be:
- Download Visual Studio 17.4.0 Preview 2.1
- Install the MAUI workload using the Visual Studio Installer
- Download a .NET 7 sample repo from https://github.com/dotnet/maui-samples
- Attempt to build
For me, the output of dotnet workload list is:

Notably, there is no maui workload like there is in previous versions.
Can build with net7-android only.. Cant run net6 builds. Microsoft.Maui.Dependencies (6.0.540) wont load.
This workaround helps getting the workloads
dotnet workload restore --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json
Same here actually. It helped download ios stuff but then started throwing.

I see the same thing. I have a 2nd PC that I updated VS 2022 today, and I am not seeing the same problems. I am trying to determine the differences. The working PC doesnt get the errors shown above with "dotnet workload list"
We are actively investigating this issue and have an idea of the problem - basically the version generated for the .msi installer created for the packages was creating an older version than the dotnet CLI tools expect to see.
We are working on this and will be publishing updated packages to make a workaround available as quickly as we can.
What is worse, VS Preview 2.1 with installed RC1 does not allow to build 6.0 MAUI applications. I see constant error in MAUI build:
Error NETSDK1147 To build this project, the following workloads must be installed: maccatalyst To install these workloads, run the following command: dotnet workload restore SCF C:\Program Files\dotnet\sdk\6.0.401\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.targets 38
Error NU1012 Platform version is not present for one or more target frameworks, even though they have specified a platform: net6.0-ios, net6.0-maccatalyst
Have you ever tried VS 2022 and VS 2022 Preview installed together with both 6.0/7.0 RC1?
Tested on latest VS Preview 2.1, it works ok on Windows. Note the Windows SDK Build Tool NuGet Package is also updated to the latest preview version (skipping the constraint shown in Nuget package installer by installing via dotnet CLI command), hope this constraint to 22000 version can be removed officially.
Hi @Redth,
When targeting to .NET 7 runtime, MAUI project automatically installs many Xamarin-related NuGet Packages, including:
Xamarin.AndroidX.Browser, Xamarin.Android.Legacy.Support.V4, etc.
See the attached image for details.
"Implicit Referenced By SDK", can't be removed. Quite weird, since this is a MAUI project.
What is worse, VS Preview 2.1 with installed RC1 does not allow to build 6.0 MAUI applications. I see constant error in MAUI build:
Error NETSDK1147 To build this project, the following workloads must be installed: maccatalyst To install these workloads, run the following command: dotnet workload restore SCF C:\Program Files\dotnet\sdk\6.0.401\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.targets 38
Error NU1012 Platform version is not present for one or more target frameworks, even though they have specified a platform: net6.0-ios, net6.0-maccatalyst
Have you ever tried VS 2022 and VS 2022 Preview installed together with both 6.0/7.0 RC1?
Can report the same, Vs 2022 is now broken too on my machine with maui 6.
I can reproduce the same issue in macOS with the following versions installed in case it helps

Workaround that I used and worked for me. Seem that Dotnet get mixed-up when multiple framework are installed.
in bash: Locate Dotnet folder with Find, the one withthe sdk and runtume folder. rm -rf Dotnet. Reinstall sdk and runtime You’ll get a fresh 6 and 7 installation Worked for me
Not overly helpful but can confirm I ran into this issue myself yesterday. I had to revert back to Preview 7 which after some fiddling around resolved the issue.
I too ran into this problem after upgrading Visual Studio to 17.4.0 Preview 2.1.
However, I then tried restoring the workloads as suggested above with this command:
dotnet workload restore --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json
The command sucessfully installed everything: Welcome to .NET 7.0!

I then did a Clean project, deleted bin and obj folder and am finally rebooting my machine n...
ow. Well didn't work out that way. Now, Visual Studio does not recognize my .NET MAUI project anymore and suggests installing extra components for a full development experience instead. However, when trying to do so, it also explains that everything is already in place.
Result: My .NET MAUI setup is completely broken... :(
Same issue with me getting kind of tired with MS working on staff only builds and releasing stuff that is not customer ready ! My issue is on windows 11
We have some newer packages we will publish soon after a bit more validation.
If anyone is willing to try and install them from the staging feed, you can try the following commands:
dotnet --verson
Make sure you are running dotnet commands within the context of 7.0.100-rc.1 (ideally the exact version is 7.0.100-rc.1.22431.12)
NOTE: The context matters when you run these commands and it's possible if you run them from a current directory that has the sdk version pinned from a global.json file, things will not run as you might be expecting. This goes for all dotnet commands!
Run the following command exactly:
dotnet workload install maui android ios maccatalyst macos --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/net7.0-rc.1.2.json --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json --source https://api.nuget.org/v3/index.json
If you try this, please report your results!
Tried that, didn't work. There's some signature missing:
Added --skip-sign-check as suggested by @jamesmontemagno

7.0.100-rc.1(ideally the exact version is7.0.100-rc.1.22431.12)NOTE: The context matters when you run these commands and it's possible if you run them from a current directory that has the sdk version pinned from a global.json file, things will not run as you might be expecting. This goes for all dotnet commands!
Run the following command exactly:
dotnet workload install maui android ios maccatalyst macos --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/net7.0-rc.1.2.json --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json --source https://api.nuget.org/v3/index.jsonIf you try this, please report your results!
This worked for me! I was originally getting the following error:
platform version is not present for one or more target frameworks, even though they have specified a platform: net7.0-maccatalyst
but now I can build without errors!
Tried that, didn't work. There's some signature missing:
Added --skip-sign-check as suggested by @jamesmontemagno
Failed anyway:
That version it's looking for was never published to nuget, so presumably at some point you did an install/update with additional package sources in the context of that update that aren't included now.
I'd rather not confuse this thread with this side issue, please follow up with James, I have some ideas.
dotnet workload install maui android ios maccatalyst macos --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/net7.0-rc.1.2.json --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json --source https://api.nuget.org/v3/index.json
@Redth Thanks! This worked for me. I was able to successfully build on .NET 7 rc1 + MAUI rc1 + Xcode 14 + Jetbrains Rider. I'm running into a problem with running the app. But that issue is tracked on https://github.com/xamarin/xamarin-macios/issues/15954
I've been struggling this for the past few days, but I persevered after reading some of the comments here. I got it fixed in the end, but there are clearly some bugs to be ironed out with the overall process.
Here is what I experienced:
If you have the .Net 7 RC1 SDK installed, and then you install Visual Studio 17.4.0 Preview 2.1 - dotnet workload list would look something like this (note the ugly error):

Use `dotnet workload search` to find additional workloads to install.

In the scenario above, it seems to be necesary to manually uninstall ios, maccatalyst and macos workloads like so:
dotnet workload uninstall ios
dotnet workload uninstall maccatalyst
dotnet workload uninstall macos
Once done, you can install using the command posted by @Redth earlier (with the skip signature flag enabled:
dotnet workload install maui android ios maccatalyst macos --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/net7.0-rc.1.2.json --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json --source https://api.nuget.org/v3/index.json --skip-sign-check
After doing this I was able to build.
Additionally - in case it helps anyone else - I did find strange behaviour when attempting to install Visual Studio 17.4.0 Preview 2.1 without having .Net 7 RC1 installed beforehand.
In this scenario, I found that "maui" would not appear in my workload list during dotnet workload search - even when I had the "MAUI" workload checked in the VS installer.
As a result, atempting to use the suggeted fix above would not work and would display "Workload id maui is not recognized".
Using the "Repair" tool in the Visual Studio Installer was necessary to make the "maui" workload appear. It is odd that this would be required for a 'fresh' install - but that was my experience.
