Visual Studio 2022 VUE3 Project Won't Start "Unable to start debugging" - vuejs3

Background: I have a VUE3 WebApp created using the VS2022 templates
https://learn.microsoft.com/en-us/visualstudio/javascript/tutorial-create-vue-app?view=vs-2022
that was working well on a desktop (Windows 10 Pro) and a laptop (Windows 11 Home); i.e. I could open Visual Studio 2022; have the WebApp as the start-up project; click run/debug and it would run up.
Current Issue: On the desktop this continues to work as expected; however on the laptop when I go to startup the WebApp I get a message "Unable to start debugging. The startup project cannot be launched. Ensure that the correct project is set as the startup project. .... Additionally make sure its debug settins are correctly configured in project properties"
Project Properties: the two machines have the same project properties; nothing really in there other than Startup Command is npm run serve
I don't believe I've changed anything and the two machines are using the same source control repository and branch; just wondering how I work around this / what might have changed. I've done Visual Studio 2022 Updates on both machines (so up to current version on both machines). One difference is on the WebApp project if I right click, select Debug, on the laptop the options are all greyed-out; on the desktop you can select "Start new instance", "Start new instance with debugging", etc..
Any ideas on what is happening here? Or troubleshooting steps I can take to resolve?

IISExpress shows up as host for browser in Visual Studio and messes up everything - how to get back to local?

All of a sudden after I installed Microsoft Edge on Windows 10 gd, Visual Studio is using IIS Express when debugging a web application and it is messing up everything.
How do I get back to normal, so that stupid IISExpress is not used anymore?
Go to the project settings and on the web tab is a drop down that allows you to choose which engine to use.
I went to Project > Properties > Startup Project and then set my start up projects to start the services I need and my project. This reverted my button back to just "Start".

A deployment error in Xamarin.Forms UWP when deploying from a PC to itself

When I just installed a Visual Studio 2017 and created my Xamarin.Forms application, it ran fine on my Windows 10 PC. However, I then installed some apps from Steam (which is the only thing I can think of that could change system settings). After that, when I try to create another Xamarin.Forms project, it does not deploy well to my machine and gives the following error:
DEP6200: Bootstrapping failed. Device cannot be found.
SmartDeviceException - Deployment failed because no
device was detected. Make sure a device is connected
and powered on. [0x80131500]
Strangely enough, my first app continues to build and run fine, even if I uninstall it from Windows and then deploy it again.
What could be the issue?
I have just noticed that Visual Studio makes ARM the default architecture. Changing it to "Any CPU" brought back the option to run the app on my machine.

UWP project needs to be deployed before it can be started

I am using visual studio 2017, created a new xamarin forms project and tried to run the UWP project. It shows the following error:
the project needs to be deployed before it can be started. verify the project is selected to be deployed the solution configuration manager, or deploy it explicitly by clinking one of the deploy commands in the build menu.
I have looked at all online solutions and only found that you need to set the cpu to x86 and to check the deploy checkbox under the configuration manager under the solution. Both these options don't work. I still get the same error. I have also tried every cpu option including ARM.
Have you tried to uninstall the existing UWP app from the Windows Start menu > All apps? Then deploy again from VS. It did the trick for me.
Sometimes when I create an app packet for win store; Visual studio seem to get hung up building to the packet (project needs to be deployed before it can be started -error).
I solve it by creating a new app packet.

Visual Studio 2017 Doesn't Run Core Apps with IIS Express

I am having an issue with Visual Studio 2017 RC where when I run an MVC and/or WebAPI app using IIS Express the app never actually runs. Instead I get stuck with a page in the browser indicating it is trying to attach and from there it goes no further. If I open another tab/window in the browser and try to navigate directly to the launch URL, it just spins forever. Likewise when I run this using the dot net run command, the app launches and runs fine.
There do not seem to be any errors that I can see, just that the browser spins indefinitely without actually ever loading the page/endpoint.
Note: this occurs for most any circumstance. Newly created project in VS with no changes, known working project from previous versions, etc.
You could follow or upvote the issue: https://developercommunity.visualstudio.com/content/problem/11391/aspnet-core-iis-express-httplocalhost51733-failed.html
Looks like our workarounds meanwhile are
dotnet run
Publish to local IIS. Which is working for me.
(Untested: downgrade from core-1.1 to core-1.0)
If you aren't familiar with VS2017/asp.net:
You have, or can reveal via View Menu-->Other Toolbars :
Debug toolbar --> dropdowncombobutton saying "[green arrow>] IIS Express"
Click on the dropdown downarrow part of the button.
You should see a Run {yourprojectname} option.
This is the equivalent of dotnet run {yourprojectname} from the commandline.
You can configure the options that appear in the dropdown with
Right-click on project in solution explorer --> Properties --> Debug
I had this same issue and after digging around for a while I discovered that I had dotnet preview v1.0.0-preview2 installed under Programs Files (x86) and a non-preview version in x64. I think VS is launching the x86 (preview) version but expecting to see the full version. To fix this, I did the following.
from programs and feature uninstall every visible dotnet core. (note: for me this did not remove the x86 preview)
go to https://www.microsoft.com/net/download/core#/sdk and install BOTH x86 and x64 SDK packages
open command line and from the root directory check run: dotnet --version (at the time of writing it was 1.0.4)
fire up .net core project in VS 2017 and run.
When I did all of the above, I was able to start up the site in IIS Express from VS.

Visual Studio 2015 - Opening two projects in debug mode

I'm using Visual Studio Ultimate 2015 CTP (Version 14.0.22512.0 DP), and create two asp.net 5 vnext web applications.
When one is running, and I'm starting the second one with the context menu "Debug->Start new instance" option, the IIS Express crashes instantly (Internet Explorer opens firstly the second project, and then instantly closes both, Chrome simply display only that the page doesn't exist).
The only trace that I found is in the Event Viewer, a Warning from IIS Express:
The directory specified for caching compressed content C:\Users\Alek\AppData\Local\Temp\iisexpress\IIS Temporary Compressed Files\Clr4IntegratedAppPool is invalid. Static compression is being disabled.
Any suggestions how to fix this? It's hard to work on a multi-tier project when only one project can be run at a time.
When I created manually above folder, nothing is logged to the event viewer, but the IIS Express still crashes. On Visual Studio 2013 I can run two instances of two Web Applications withtout any problems
It should work if you set your solution to use multiple startup projects and add all the projects you need to debug
Really easy steps to follow here:
http://www.magnetismsolutions.com/blog/paulnieuwelaar/2015/04/07/debug-multiple-projects-at-the-same-time-in-visual-studio
Still not as easy as previous versions of visual studio
Maybe not a solution, but a workaround which I found - running two instances of Visual Studio 2015 allow to run two projects.
