Unable to build a project with net7 RC 1 #10234

florianwachs · 2022-09-21T09:08:22Z

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:

Installed Workload Id      Manifest Version                 Installation Source

dotnet workload search is:

----------------------------------------------------------------------------------------------

wasm-tools                 .NET WebAssembly build tools

Notably, there is no maui workload like there is in previous versions.

Same issue

Can build with net7-android only.. Cant run net6 builds. Microsoft.Maui.Dependencies (6.0.540) wont load.

virzak · 2022-09-21T17:08:49Z

This workaround helps getting the workloads

dotnet workload restore --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json

codemonkey85 · 2022-09-21T17:22:02Z

@virzak It doesn't seem to help me...

@virzak Didnt help me either

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"

Redth · 2022-09-21T19:47:37Z

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.

florianwachs · 2022-09-21T19:53:10Z

Great! can't wait to try it

foximoxi · 2022-09-21T21:36:09Z

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?

SunshineSpring666 · 2022-09-22T04:25:41Z

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.

SunshineSpring666 · 2022-09-22T06:15:10Z

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.

SunshineSpring666 · 2022-09-22T08:13:35Z

"Implicit Referenced By SDK", can't be removed. Quite weird, since this is a MAUI project.

florianwachs · 2022-09-22T10:25:41Z

Can report the same, Vs 2022 is now broken too on my machine with maui 6.

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.

Mephisztoe · 2022-09-23T19:34:18Z

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:

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

Redth · 2022-09-23T21:10:02Z

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!

Mephisztoe · 2022-09-23T21:21:19Z

Tried that, didn't work. There's some signature missing:

Added --skip-sign-check as suggested by @jamesmontemagno

Failed anyway:

This worked for me!
I was originally getting the following error:

but now I can build without errors!

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.

@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 dotnet/macios#15954

Conbag93 · 2022-09-26T10:11:44Z

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):

Installed Workload Id      Manifest Version                  Installation Source

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.

davidbuckleyni · 2022-09-27T08:58:41Z

That seemed to have better sucess will try running the app now

davidbuckleyni · 2022-09-27T09:03:45Z

Still getting futher issues here

Redth · 2022-09-27T12:47:10Z

We've published the packages after validating they install and correct the specific issue where you installed a standalone .NET 7 RC1 SDK before installing VS 17.4 P2.1.

Until we're able to ship an update with the next VS 17.4 preview, you can work around it with the following:

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

Thanks for your patience!

Hello - with reference to my earlier comment - based on my experience - I do not think command alone is enough.

If you have .NET 7 RC1 pre-installed, then running dotnet workload list throws a Dictionary exception.
The same exception is thrown when running this command, and the workloads are not installed.

I had to manually remove the offending workloads before dotnet workload install maui android ios maccatalyst macos would run without issues.

florianwachs · 2022-09-27T14:57:58Z

worked for me, thanks a lot for your work!

codemonkey85 · 2022-09-27T15:13:25Z

Unfortunately that isn't working for me: Workload installation failed: One or more errors occurred. (Response status code does not indicate success: 401 (Unauthorized).)

matt-goldman · 2022-10-01T23:05:28Z

Since installing the latest Visual Studio preview I've been getting this error:

I've tried installing the tizen workload, removing tizen as a TFM from my project, and I've tried running dotnet workload restore as per the suggestion with the error.
I've also tried all the suggestions here to no avail. I went the brute force approach and uninstalled every version of Visual Studio, every dotnet workload, and then installed a fresh instance of Visual Studio 2022 Enterprise. And I still get this error.

I think I've hit reinstall Windows territory. Is there anything else I can try first?

Edit to add: I'm assuming this is the same issue as mentioned here but if not let me know and I will open a new one.

davidbuckleyni · 2022-10-05T03:31:00Z

Thid is still not solved

tsjdev-apps · 2022-10-06T05:55:00Z

I'm still struggeling. I've already tried to uninstall Visual Studio and also Visual Studio Preview from my Windows machine. After installing only Visual Studio again, I encountered the same issue. The only workaround for me is to remove the net6.0-ios and net6.0-maccatalyst from the csproj file. So is there any other workaroung for .NET 6.0 MAUI apps?

davefxy · 2022-10-06T12:40:52Z

I believe you can use the global.json file. Put it in the project directory (same place as csproj). This will indicate to VS that the project should use Net 6. In this file put the following:
'{
"sdk": {
"version": "6.0.400",
"rollForward": "latestMinor"
}
}'
