New Visual Studio 2022 Install - Cannot publish any .NET 7 MAUI Blazor app for Windows _GenerateAppxPackage

[shyftkenney]

Description

It's impossible to publish any .NET MAUI Blazor app including one straight from the project template. It simply does not work with the latest version of everything installed.

Severity Code Description Project File Line Suppression State
Error MSB4057 The target "_GenerateAppxPackage" does not exist in the project.

It seems completely broken. It has been reported but no response has been received yet after several days. Any patches or things to look at in the local environment would be great. The machine is a windows computer with the latest version of Windows 11 installed. It literally could not be more current.

Steps to Reproduce

1. Create a new .NET MAUI BLAZOR project
2. Build a release version
3. Try to publish the app (sideload)

Link to public reproduction project repository

https://github.com/dotnet/maui

Version with bug

7.0 (current)

Last version that worked well

Unknown/Other

Affected platforms

Windows

Affected platform versions

Windows 11

Did you find any workaround?

The only way to publish right now is to use the CLI

Relevant log output

Severity	Code	Description	Project	File	Line	Suppression State
Error	MSB4057	The target "_GenerateAppxPackage" does not exist in the project.

@shyftkenney thanks for contacting us.

Could you generate a binlog so that we can take a look? Or can you at least include the line and the file that is producing this error?

Did you follow these instructions? https://learn.microsoft.com/dotnet/maui/windows/deployment/publish-visual-studio-folder

I just did a test now with a brand new app and I was able to publish. Does it work with a File | New | Maui App template? What options did you select when publishing? Providing the logs from the Output window or even a full binlog (https://github.com/xamarin/xamarin-macios/wiki/Diagnosis) will really help us see what you are doing differently to me.

I am seeing this too, and have been for a month or so. I think it might have started with the .NET 7 service release.

CLI works.

I am also experiencing some issues doing a "dotnet workload update"

Warning: Workload garbage collection failed with error: An item with the same key has already been added. Key: (Microsoft.NETCore.App.Runtime.Mono.android-arm, 6.0.13).

It is possible that this oddity is unrelated.

[shyftkenney]

It does not work for me with a *.NET MAUI Blazor* default template application. I sent one over that went to the Senior Program Manager as an example.

I ran another dotnet workload update after the latest service release and I'm able to publish now.

[shyftkenney]

Oh that's great news! I'll give that a try. Thank you Edward!

I have exact the same problem. NET MAUI Blazor, target windows only, VS 17.4.4
I have different image for "Set the build target" as Publish a .NET MAUI app for Windows with Visual Studio

[shyftkenney]

I actually gave up and just deployed this as a blazor web app instead. I'll come back to MAUI after this is all worked out though. Super cool stuff!

I find that sometimes commenting out other target frameworks in the csproj, and then reloading the project, can help in general.

In addition to running "dotnet workload update, " I would check out the new update to the Single-Project MSIX extension for visual studio.

[AlexNek]

I have Version: 1.2.0.2211083

[AlexNek]

I actually gave up and just deployed this as a blazor web app instead.
I want to use "file save as" so it will be no so easy to switch.
Where is the time, when I can simple start the exe.

[symbiogenesis]

I would also try to set the target framework to net7.0-windows10.0.22621.0 if possible. And I would restart visual studio after performing the workload update and extension update.

This particular bug seems solved to me, and needing to use "dotnet publish" via CLI wasn't so bad.

Publishing as an EXE is something that is under development, and I'm looking forward to this as well.

But windows store deployments with these new style msix bundles are pretty painless, and you can distribute to only a private audience if you want, and you get free auto-upgrade capability.

[symbiogenesis]

Apparently you should already be able to publish as EXE if you aren't using one of the known incompatible features.

#8552

[AlexNek]

I have now net7.0-windows10.0.19041.0
Why was net 7.0-maccatalist there?

[AlexNek]

you aren't using one of the known incompatible features.
I think so but no success. In addition, I have DLL and error for that project - NETSDK1094: Unable to optimize assemblies for performance: a valid runtime package was not found... So CLI publish not possible too

Same problem here

Hi @shyftkenney. We have added the "s/needs-repro" label to this issue, which indicates that we require steps and sample code to reproduce the issue before we can take further action. Please try to create a minimal sample project/solution or code samples which reproduce the issue, ideally as a GitHub repo that we can clone. See more details about creating repros here: https://github.com/dotnet/maui/blob/main/.github/repro.md

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

[AlexNek]

That is very easy. Try to use default MAUI Blazor template and then Publish.

[mattleibow]

When you say publish, is this in the IDE or the CLI? Can you send a screenshot of which menu item you select to publish if this is the IDE? I know there are a several publish options in the IDE so maybe one of the others are appearing.

[AlexNek]

IDE of course /I use only one place on the solution explorer/. CLI is "not existing" for me. I use windows not *Nix.
With CLI it is working sometimes. (I have troubles with additional project)

I can't publish using Visual Studio, works using the terminal...

getting the error:

Error	MSB4057	The target "_GenerateAppxPackage" does not exist in the project.	JewelsCafe	C:\....csproj	1	

Works fine on .Net 6.0... I'm using the same solution...

Steps to reproduce...

Switch your project if not already to .Net 7.0 (or to 6 to make it work, or test)
(in my case, I disabled all targets except Windows)
Build > Pack (or Publish)

[mattleibow]

I still can't reproduce this. I tried both a normal and a blazor maui app using the stable version of VS 17.4.4 using maui 7.0.52.

All works fine without an issue.

The only thing that I can think that can cause this issue if the Microsoft.WindowsAppSDK nuget got corrupted as that is where this target lives. Can you try clearing the nuget cache? Or deleting the C:\Users\<username>\.nuget\packages\microsoft.windowsappsdk folder.

The only way for me to diagnose any issues is with a sample project - even if it is the template because maybe your templates are corrupted - and with a binlog as that tells me what actually happened and what called what.

https://github.com/xamarin/xamarin-macios/wiki/Diagnosis

Many things will happen, but you should get a publish item somewhere:

Save that and attach it here. I will have a look and see what I can find... The missing target sounds like something is not getting included.

[AlexNek]

Thanks for the answer. I try to replay all again and have curious behavior. Immediately after project creation I can deploy it.
Then I try to remove android and macos. After at in MS GUI I can see Deploy menu item but happens nothing.
MauiBlazorApp8.zip

Why for only windows I have maccatalict target "TargetFrameworksnet7.0-maccatalyst /TargetFrameworks?" Sometimes I have message that it is impossible to debug that under windows. Sometimes I can start application with debug.
You can find my sample in attachment.
Thanks
