Microsoft Visual Studio Professional 2022 Version 17.0.4
Starting from scratch a "Multi-Platform App (Uno Platform|net6)" project, closing the solution and reopening it, the "mobile" project is listed as "incompatible".
It happened to me on two different computers.
I run the "uno-check" and after installing the missing parts it tells me that everything is ok, but when I load the solution the mobile project continues with the same error.
Any idea?
The .NET 6 mobile project template is only supported on Visual Studio 17.1 Preview 1 and later.
I leave the link where he explains that the problem is in the manifest of the packages.

I am trying to follow this tutorial: https://learn.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/razor-pages-start
However, when I get to the Create a Razor Web App section, there is no template in my install of VS2017.
I have both the .net core and asp.net and web dev workloads installed. Where have I gone wrong?
Open Visual Studio (assuming its 2017) and go to: Tools > Extensions and Updates
Click "ASP.Net and web development", then select the appropriate Individual Components in the right hand pane. You'll find components such as ".Net Core 2.0 Development tools" and ASP.Net web development tools"
Have you got the latest update for your Visual Studio installation?
Head to Add or Remove Programs
find Visual Studio
Click Modify
Allow the installer to update
Install any updates that are missing
On top of that, do you have the latest version of the .NET Core SDK?
It seems I had an OS issue that caused updates to fail. Have rebuilt the PC and all working as expected now. Very much a sledgehammer approach, but this was something fundamentally wrong with the installation.
I have missing MVC template in Visual studio 2015. I followed every answer posted in this topic in stackoverflow. I tried modifying and installing again and i checked web developer section too. But still MVC template is not in web section.
Seems like you have forgotten to install Web Developer tools on the initial installation.
After reinstalling this, everything reappears

I'm getting a curious error when attempting to generate a view via the 'Add View' dialog. Simply leaving the dialog as is (ie creating view 'View') and hitting 'Add' yields the following error dialog:
Error: There was an error running the selected code generator: 'The Templates/PackageVersions5.0.1xml file is missing from the installed template folder.'
Which I'm afraid means little to me. I've googled the xml file to no avail.
Not really sure where to go now - I'm unable to add views to my project via scaffolding (though I can of course just by 'adding a new item' and building it myself).
How can I track down the source of this error?
Posting here because I ran into the same "file is missing" issue with Visual Studio 2019 and PackageVersions5.2.6.xml. This was one of the only pages I could find related to this scaffolding issue so I suspect others will find their way here too.
I found that upgrading the "Microsoft.AspNet.Mvc" package via NuGet to 5.2.7 was not sufficient to fix the problem. I also had to upgrade "Microsoft.AspNet.WebApi" and its related packages to 5.2.7. The Add View option started working again afterward.
Just make sure you have same version of MVC nugget in all projects, if you only have one project then upgrade/downgrade MVC to different version then revert back to the version you require and issue will get fixed.
I just changed version from 5.2.3 back to 5.2.2 and then reverted back to 5.2.3 and all worked. It appears some file got messed up or and then was restored by this.
I got same issue while using visual studio 2019 community edition, where I am able to create view using visual studio 2017.
After reading answers here, I tried upgrading Microsoft.AspNet.Mvc package, and it works for me.
I'm afraid the rather unsatisfactory solution I arrived at was to create a clean project and import the project elements in, recreating the project from scratch.
I assume that some deep-configuration had become corrupted and I was unable to work out how to fix it.
I ran into the same problem when using a project from VS2013 in VS2015. In my case it was PackageVersions5.1.3.xml that was missing. 5.1.3 seems to be the version of MVC this project was using. I updated MVC to the latest (currently 5.2.3) and this solved the issue.
The XML file should exist in C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web\Mvc\Scaffolding\Templates\
I had the same issue. The problem started after installing DevExpress to project. I found that DevExpress installation creates some DevExpress folders in D:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions but all necessary files for scaffolding lived in D:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\Extensions. I copied the content of extension folder from vs professional to enterprise restart Visual Studio and Scaffolding works again.
has anyone else dealt with this? My ultimate goal is to create a new empty web api project. I've been following tutorials and I've encountered the following issue:
My issue is that when I try to create a ASP.NET Web Application project in Visual Studio Pro 2012 I do not see that template as an option. I go to Installed --> Templates --> Visual C# --> Web
All I see is ASP.NET Empty Web Application. So I selected that and then expected the ASP.Net project window to pop up so that I could select "Web Api". However, that dialog never opened.
Does anyone know how/where I can get the ASP.NET Web Application template?
I came across your question as I had the same problem. When I first installed Visual Studio I didn't tick the box to install the Web Components. Here is how I solved the issue:
Close all your instances of Visual Studio.
Run the Visual Studio Installer (I found mine in the Downloads folder still and was named "vs_professional.exe").
For VS 2013 a grey window appears similar to when first installing VS.
When prompted select "Modify" from the list of options.
Tick the list item which I think was named "Web Development" or something similar.
Click update.
Once the installer has finished running launch Visual Studio.
When selecting New Project in Visual Studio I can now see the required templates.
Try to select Framework 4.5.
The Framework 4.0 don't have :)

If you have ASP.NET MVC 4 Web Application as an option under Web when you select it as a new project the project window pops up and you will be able to select Web API.
kale909's solution worked for me. I just added pics here to make it more clear:
