dotnet build/msbuild fails on GenerateResource Task with .NET 6

I try to build my project in my CI/CD pipeline with a gitlab runner, but I always end in the following error message:
C:\Program Files\dotnet\sdk\6.0.100\Microsoft.Common.CurrentVersion.targets(3264,5): error MSB4216: The GenerateResource task could not be performed because MSBuild could not create a task host or connect to a task host with runtime CLR4 and architecture x86. Make sure that (1) the requested runtime and/or architecture is available on the computer and (2) the required executable file "C:\Program Files\dotnet\sdk\6.0.100\MSBuild.exe" exists and can be executed. [project_path]
C:\Program Files\dotnet\sdk\6.0.100\Microsoft.Common.CurrentVersion.targets(3286,7): error MSB4028: The output of the GenerateResource task could not be retrieved from the FilesWritten parameter. Object does not match target type. [project_path]
I´ve installed .NET6 SDK with version 6.0.100.
It seems like its trying to find the msbuild.exe and it´s not there. I´ve copied the file temporarely but this causes a endless building without result or error message.
Am I missing something? In my Visual Studio 2022 the build process is working and generating my binaries.

Error Metadata file dll could not be found CSC when publishing

I have a Visual studio solution with several projects in it, specifically a DotNet5 asp.net app, that has several netstandard 2.0 references on it. it builds and runs fine in the debugger but continuously throws the metadata errors. It keeps specifically referencing its looking for a net5 folder in the netstandard2 project. I cannot find where its getting this from, the problematic one used to be a multitargeted project against framework 4.7, 4.8, and net5.0, but i got annoyed with the multiple dll's and just migrated it to standard2.0 and had no issues till i want to publish it.
I've tried what a few other questions referenced, cleaning, rebuilding, remove and re add references to other projects, deleted the obj and bin folders out of the solution, the removing the sou file, tried VS 2019 (16.9.0 preview 2) preview vs 2019 (16.8.3) release, different computer (pulled back down from a lan git repository) and got the same error.... also tried searching the entire solution for references to net5.0 and didn't find it outside of the expected locations like the csproj for the asp.net project and its respective pubxml. And just for fun, I temporarily retargeted the library project back to net5.0 and it still threw the same error even when the exact file and path listed did exist.
Using enters for the error below for the different columns in the error message, and removed the "sensitive" info. There is no error code provided by Visual Studio. Anyone else got any more ideas on what to try?
Error

Edit: adding a couple other sections of the error messages:

Got it to publish but I am so confused....something to do with the publish profile. If i delete that and generate a new one, works fine. as soon as i edit it using the GUI, broken....generate it again. So far seems ok to edit it manually but TBD. not sure if the "fix" will survive restarting Visual studio or not.
Edit - Scratch that, found the difference.
Remove the following line in Properties/FolderProfile.pubxml and it's fine.
<TargetFramework>net5.0</TargetFramework>

SonarQube unrecognized command line argument c#

PD: I'm running sonarqube version 6.7.1 and MSBuild

The second command you execute should be just msbuild.exe, not SonarQube.Scanner.MSBuild.exe.
Edit:
The problem, is indeed that I have to execute MSBuild.exe instead of the other one but if you can't execute that, it may be because you don't haven't configured your environment varables, and path. If you can't execute it simply look for your MSBuild folder in Program Files (x86), in the end you should execute this:
'C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe' /t:Rebuild
so this should be it.

Documentation needed on how to get FXCop running with Sonarqube 5.1

On the sonarqube website the new C# plugin documentation states 'native support for fxcop'
However there is no explanation how to get fxcop running. It does not work out of the box.
What i did so far and works:
installed Sonarqube 5.1
using msbuild.sonarqube.runner
The sonarqube C#,xml,js analysis al work like a charm.
What does not work is using fxcop rules.When i enable 1 rule i get the runner to give the following exception:
ERROR: Error during Sonar runner execution
org.sonar.runner.impl.RunnerException: Unable to execute Sonar

her.java:91)

FxCop ru les. This property can be automatically set by the Analysis
Bootstrapper for Visual Studio Projects plugin, see:
http://docs.codehaus.org/x/TAA1Dg.If you wish to skip the analysis of
not built projects, set the property "sonar.visu
alstudio.skipIfNotBuilt".
What i tried so far:
followed the provided docs.codehaus.org/x/TAA1Dg link but this is a dead link. It states "All Codehaus services have been terminated".
added sonar.cs.fxcop.assembly property to the sonarqube.analysis.xml but this does not change anything to the error.
added sonar.cs.fxcop.installdirectory property to the sonarqube.analysis.xml file. This changes the error messages to:
Caused by: java.lang.IllegalArgumentException: Cannot find the
assembly "C:\p
rojects\mercurial\ccvs.sonarqube\bin\sonar-runner\bin\"FxCopCmd.exe""
provided by the property "sonar.cs.fxcop.assembly".
But i'm unable to the the fxcop installation copied to this folder. I also failed to influence the path to be redirected to my fxcop installation which comes with vs2013(C:\Program Files (x86)\Microsoft Visual Studio 12.0\Team Tools\Static Analysis Tools\FxCop\FxCopCmd.exe)
Another thing is that the sonar-project.properties file next to the .sln file is not picked up by this new msbuild sonar runner thats why i edit the xml file.
In short a step-by-step on the guide how to get fxcop working together with sonarqube 5.1 and the msbuild sonarrunner on the site of sonarqube would be appreciated.

I thinks you should read
http://www.sonarqube.org/easy-analysis-of-visual-studio-solutions-with-the-sonarqube-scanner-for-msbuild/
and
http://docs.sonarqube.org/display/PLUG/C%23+Plugin .
Pay attention to the fact that you should run the commands from a "Developer Command Prompt for Visual Studio 2013 or higher" (http://docs.sonarqube.org/display/SONAR/Analyzing+with+SonarQube+Scanner+for+MSBuild).
Neither DOS Command Prompt nor Windows PowerShell work because they don't set the proper variables.
The FxCop native support doesn't mean that it comes with MSBuild SonarQube Runner, but you have to install Visual Studio >= 2013 (as I think you understood from your message).
Moreover, I found that not only sonar-project.properties has been deprecated, but you have to remove it to avoid strange behaviors.

How to set FxCop installation path using SonarQube's C# plugin

I'm trying to analyze .NET C# project using SonarQube C# plugin.
From C# Plugin 3.0, FxCop is automatically executed even thogh "sonar.fxcop.mode=skip" in sonar-project.properties, so I installed FxCop to following directory.
C:\Program Files (x86)\Microsoft FxCop 1.35
When I ran SonarQube Runner from Jenkins's sonar plugin, then I got following error.
ERROR: Error during Sonar runner execution
ERROR: Unable to execute Sonar
ERROR: Caused by: The property "sonar.cs.fxcop.assembly" must be set.
ERROR:
ERROR: To see the full stack trace of the errors, re-run SonarQube Runner with the -e switch.
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.
Build step 'Invoke Standalone Sonar Analysis' marked build as failure
Finished: FAILUR
I enabled Visual Studio Bootstrapper on SonarQube, and I ran SonarQube Runner again, then I got following error.
ERROR: Error during Sonar runner execution
ERROR: Unable to execute Sonar
ERROR: Caused by: java.io.IOException: Cannot run program "C:/Program Files (x86)/Microsoft Visual Studio 12.0/Team Tools/Static Analysis Tools/FxCop/FxCopCmd.exe": CreateProcess error=2, ?w?????t?#?
ERROR: Caused by: Cannot run program "C:/Program Files (x86)/Microsoft Visual Studio 12.0/Team Tools/Static Analysis Tools/FxCop/FxCopCmd.exe": CreateProcess error=2, ?w?????t?#?

ERROR:
ERROR: To see the full stack trace of the errors, re-run SonarQube Runner with the -e switch.
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.
I add "sonar.fxcop.installDirector=C:/Program Files (x86)/Microsoft FxCop 1.35" to sonar-project.properties, and ran SonarQube Runner again however same error occured.
I guess if Visual Studio Bootstrapper disabled and sonar-project.properties specify "sonar.cs.fxcop.assembly" and "sonar.fxcop.installDirector" correctly, It's work fine, but I don't want to specify many properties in sonar-project.properties.
How can I set FxCop execution path with enabling Visual Studio Bootstrapper?
Environment:
SonarQube4.2
SonarQube's C# plugin 3.0
SonarQube Runner 2.4
sonar-project.properties
sonar.projectKey=xxxxx
sonar.projectVersion=1.0
sonar.projectName=Project Name
sonar.language=cs
sonar.dotnet.key.generation.strategy=safe
sonar.sourceEncoding=UTF-8
# This property is set because it is required by the SonarQube Runner.
# But it is not taken into account because the location of the source
# code is retrieved from the .sln and .csproj files.
sonar.sources=.
sonar.fxcop.mode=skip
sonar.gendarme.mode=skip
sonar.gallio.mode=skip
sonar.ndeps.mode=skip
sonar.stylecop.mode=skip
sonar.fxcop.installDirector=C:/Program Files (x86)/Microsoft FxCop 1.35
Regards

I found the solution for this issue , Login as an administration on sonar qube and then go to setting , under general setting you find Category, select C# then Click on Code Analysis/FxCop tab , then find "Path to FxCopCMD.Exe" and add the full path of FXCopCMD.exe as suggested in example
click on this to see image and process

Same problem here. I think after you installed Visual Studio Bootstrapper you'll need to setup the following key to match the path to FxCop executable:
sonar.cs.fxcop.fxCopCmdPath
which by default has the value you mentioned in the second error log.
