I'm facing an annoying problem involving my installation of Visual Studio 2015 Enterprise. I just got into a cross platform mobile project and I have fetched the source code from version control. The solution consists of several mobile projects (Android, iOS) that work fine and a UWP project that refuses to load. It says on the solution explorer:
This project requires a Visual Studio update to load. Right click on the project and choose "Download Update"
After clicking "Download Update" I'm presented with this page: https://developer.microsoft.com/en-us/windows/downloads/sdk-archive .
I've tried downloading all three of the SDKs (I don't think it's an emulator issue so I haven't bothered download the emulator installers).
All three throw this error:
I've tried modifying my Visual Studio installation from the control panel but as you can see the installer claims all Windows SDKs are currently installed:
I've tried re-installing the SDKs. I've tried reinstalling Visual Studio 2 times, one of them involved a full uninstall by running
vs_enterprise.exe /uninstall /force
in a command prompt but to no avail.
Also when I try to create a fresh UWP Project the only platform I can target is the 10.0.240 build. I recall being able to target other versions in the past but the dropdown only contains this option now.
I finally solved it after quite a lot of research. I followed these steps:
Go to Control Panel > Programs & Features
Find Microsoft Visual Studio 2015, right click on it and select 'Change'
When the installer pops up select 'Modify'
Uncheck the whole 'Universal Windows Apps Development tools' section
Wait until the uninstallation is complete
Restart
Again go to Control Panel and find the SDK installers which apparently are not removed using the above method:
Uninstall them all
Restart
Visit this page: https://developer.microsoft.com/en-us/windows/downloads/sdk-archive and download all three SDKs
Start by installing version 10.0.26624 and work your way up
After you're done go to control panel find the Visual Studio Installation, right click, click 'Change' then after the wizard loads select 'Modify'
Make sure every option in the 'Universal Windows Apps Development Tools' section is checked, click Next
After the installation of the SDKs and tools is complete restart your computer
The error should be gone now
I ran into this error trying to add a Portable Class Library project to a solution. It occurred whether I asked it to target Windows Universal 10.0 or Windows 8.1.
The workaround I used is to ask it to also target ASP.NET Core 1.0, even though I wasn't using ASP.NET.
I also ran into this which took me a lot of time to solve. Actually YOU DON'T HAVE TO REINSTALL ANYTHING! If you are totally sure your Visual Studio is up to date, just follow these steps and it will solve your problems: https://stackoverflow.com/a/35733823/3322347

I am working on a project on my laptop, and am switching laptops. It is a Xamarin Android project with C#. It is source controlled onto visual studio online / devops using the Git option. When I clone my project onto my new laptop. My project is not building. Some projects aren't loading and some of my references have errors next to them.
I think to get it working requires some necessary steps. Please tell me if any of this should not be necessary.
(1) Open Visual Studio Installer and Modify in order to add Mobile Development and .Net so that Xamarin is installed.
(2) Tools > Android > Android SDK Manager > Checkmark necessary SDKs (aka android Lollipop, etc). (If these are failing, then right click on visual studio icon to "Run as Administrator" when initially opening.
This third step is whats bothering me:
(3) Clean Solution and Rebuild. And magically every dependency and every necessary anything is automatically installed/etc.. but not true.
Instead...
Some references in your projects will have a yellow triangle icon. Go to Tools > Nuget Package Manager and when you select any of the Installed projects, there will NOT be a checkmark next to ANY projects.. weird.. but when you go to Update, and click on any needing an update, the checkmark will be there. If you select all and update, some of your yellow triangles will go away, but the checkmarks won't appear in Installed when clicking on a project and seeing which projects it is installed in on the right.
Is there some button or command I am supposed to run that will grab all the necessary dependencies for me? Instead of me having to dig around and still have a non working solution?
Can you give some examples of the error messages you are getting? Usually Project Load - Restore Nuget Packages - Clean & Rebuild works for me.
NuGet will download the packages available in the package manager. However it may happen that some packages where not installed through the sources available in the package manager or that those packages are not available anymore.
In order for all the projects to build correctly I believe the following order is necessary: (As OP, I downloaded and tried to build the project before checking to make sure I had Xamarin and the necessary SDKs, and once those were installed, it wouldn't fix the project without deleting and recloning)
(1) Do NOT clone your project from github/devops yet. Delete it if you have.
(2) Install Xamarin. Open Visual Studio Installer and Modify in order to add Mobile Development and .Net so that Xamarin is installed.
(3) Install necessary SDKs for Android OS version. Tools > Android > Android SDK Manager > Checkmark necessary SDKs (aka android Lollipop, etc). (If these are failing, then right click on visual studio icon to "Run as Administrator" when initially opening.
(4) Clone project from github/devops, and clean/build. Should work automatically.
(An aside: I feel like step 3 should also be automatic? It should know which ones I'm targeting and auto install those? Maybe it does, I'm not sure.)
I have the SDK manager for Android installed and updated on my PC currently running a Windows OS And i also have Xamarin Studio downloaded and installed for Windows.
Challenge is, i try as much as possible to create a new "Helloworld" project and the Next button has bluntly refused. What could be the issue really? I am Totally new to this
The only solution that could come thru at this Moment was installing a lower version of Xamarin. I installed http://download.xamarin.com/studio/Windows/XamarinStudio-5.9.5.9-0.msi as the community version and it didnt give issues installing and no grey out buttons in this case, Thought I'd post the answer here
I updated Visual Studio on Mac and after it tried to start, it told me I need to install Mono and directed me to a web page for that. I installed Mono. Now every time I launch Visual Studio, it just says
Could not launch Visual Studio
This application requires Xamarin.Mac native library side-by-side.
Please download and install the latest version of Mono.
I tried restarting but that didn't help.
What now?
(I'm running the latest macOS, and updated XCode if that matters. Mono is 5.4.0.201.)
New EDIT:(2022)
Users are saying there's a better way than uninstalling and reinstalling. I haven't tested it myself. See comments and answers for more information.
Previous EDIT:
Uninstalling and reinstalling is still the only way as the answer suggests, on: 2019:

The fastest and easiest way will be to uninstall and reinstall Visual Studio.
I have just ran into the same problem. I did follow the alert instructions and installed the newest mono framework from Mono websites (6.10.0). After this still the same issue. So I downloaded and ran VS4M installer and it said, it need version 6.8 of Mono framework and it did offer me to download and install this "update". So i went ahead. Still the same warning after launching VS.
Desperately enough after reading this thread I started looking for uninstall instructions (on official site). I did not want to use the script to auto-uninstall as I rather do it all by myself just for ensuring it will be everything done properly. So manual uninstall said to delete the Visual Studio app from /Application folder first. I did it. And woala: All the sudden the new app called "Visual Studio (old)" appeared (or maybe it was there already but I did not notice? Anyway, it was there). It was certainly weird, but I ran it. And it did work! Working instance of Visual Studio! I did check the updates and there was one for the app only. That was my first step straight after launching. It did download the new update and installed it correctly. Now I have end up with fully working and fully updated version of VS4M!
Conclusion:
Use VS4M installer to install all updates and necessarities to run VS4M. After this go to your /Application folder and delete "Visual Studio" app. The "Visual Studio (old)" app should appear. Run this app and update it straight away. (you might have to rename it afterwards from "Visual Studio (old)" to "Visual Studio")
Did you try going to the Applications folder? You'll see a Visual Studio.app file there and you can run Visual Studio by opening that.
I have sovled the problem by brew install --cask mono-mdk rather than brew install mono, in case anyone is installing mono through brew.
my Visual Studio does not recognize my Windows 10 SDK.
The steps to reproduce it:
Install VS 2015 Professional with update 3 and select the windows SDK for version 10.0.14393.0 as optional feature
Create an UWP App with this version
The following error is displayed in the output window:
error : The project requires a platform SDK (UAP, Version=10.0.14393.0) that is not installed. Please visit the following link for more information: http://go.microsoft.com/fwlink/?prd=12514&pver=14.0&sbp=PlatformSDKMissing&plcid=0x409&o1=UAP,%20Version=10.0.14393.0
Uninstall Windows 10 SDK 10.0.14393.0
Install Windows 10 SDK 10.0.14393.0 from the link provided in step 3
Create an UWP App with the version 10.0.14393.0 and the same error like in step 3 is displayed
further information: in the list of programs and features in the control panel the name of the sdk is:
Windows Software Development Kit - Windows 10.0.14393.795
and the version is
10.1.14393.795
My guess is that the version is wrong in the registry and therefore visual studio cannot find the sdk.
If I look under the path C:\Program Files (x86)\Windows Kits\10\Platforms\UAP I can see a directory named 10.0.14393.0 that contains a Platform.xml and a PreviousPlatforms.xml as it should.
Under the path C:\Program Files (x86)\Windows Kits\10\bin there is a directory named 10.0.14393.0 too so the SDK seems to be installed correctly
I already tried reinstalling of visual studio and several SKDs in different versions from VS or the online link and nothing worked. If I target another SDK Version like 10.0.10586 I am able to create the project.
Thank you for reading. I am thankful for every hint into the right direction.
Reinstalling Windows is not necessary. Modify the existing installation of VS2017 and remove the check next to Universal Windows Platform development, then go to the Individual components tab and select the Windows SDK 10.0.14393.
Click Modify.
Once finished, Modify the existing installation of VS2017 again and recheck the Universal Windows Platform development box and Click Modify.
Problem resolved and no restart required.
I had this same issue but resolved it by installing the .033 version rather than the latest .795. It is available on the SDK download page in the description of the SDK by clicking on the link behind 'QFE':
Windows 10 SDK (ver. 10.0.14393.795 – a QFE for 10.01.14393.033) and Microsoft Emulator for Windows 10 mobile
Also, even though it wasn't required, I uninstalled .795, then rebooted. Then installed .033 and then rebooted again prior to trying to open visual studio.
I'v already installed Windows SDK 10.0.14393.795 successfully. Then I create UWP project which targets 14393 successfully. So I could not reproduce your issue.
I already tried reinstalling of visual studio and several SKDs in different versions from VS or the online link and nothing worked.
If you have tried to repair your visual studio, but it still didn't work. You'd better use http://aka.ms/vscollect to gather the installation logs. Find vslogs.zip from %temp% folder. Please upload the file and share the link here. I will help you find the root cause according to the log file.
The solution is to reinstall windows and make a clean install of Visual Studio. Somehow the system got messed up and not even a visual studio reinstall could help.
I recently installed VS 2013 on Windows 8.1. When I open up any xaml file I get this error message below.
This happens even if I create a project from scratch in VS 2013. I've tried re-installing Windows 8.1 and VS 2013.
Has anyone come across this issue?
System.Exception Package failed updates, dependency or conflict
validation.
Windows cannot install package
App.a94e67374.a8775.a4662.ab57f.a7f1805386d2c because this package
depends on another package that could not be found. This package
requires minimum version 0.0.0.0 of framework
Microsoft.VCLibs.120.00.Debug published by any publisher to install.
Provide the framework along with this package.
I had the same error just like you.
I registered myself and got a developer licence. After registerering
I debugged the program and it all got fixed by itself
I use windows 10, to fixed it, I go to Setting -> Update & Security -> For developers, I choose Developer mode. In windows 8 and 8.1, I don't know.
the figure of setting
It happened to me as well with both VS 2013 and VS 2015. I think it's a common problem when VS is freshly installed.
I solved it both the times with running VS with administrator privileges (right click on the VS tile on Windows 8 and select "Run as Admin") and opening a XAML file with the editor. It takes some more time than usual, but then the problem gets fixed by itself.
After that you can continue using VS with standard user privileges.
Sadly none of the above solutions seemed to work for me.
My windows 8 installation is quite old and over the years, I had installed several visual studio versions such as 2010,2012 and 2013.
Even uninstalling visual studio, there will be many files and packages left behind.
I managed to fix this issue with the following steps:
1. Install Revo Uninstaller and from the options menu I enabled the "Show system components".
2. For some reason along with the visual studio 2013 ultimate installation (main application - do not uninstall this) I uninstalled two installations related to the main visual studio 2013 application such as: vs 2013 premium and vs 2013 professional apart from the main application (Repeat: Do not uninstall the main app)
3. Uninstall all the Microsoft Visual C++ runtime packages
4. Performed a repair of the the visual studio
Something else that I would rather prefer doing than performing a full repair as it takes far too long, would be to uninstall all the visual C++ runtimes packages and anything related to them (you might brake some apps but they are easy to find and easier to install)
and simply reinstall those visual c++ redistributes starting from the latest version and see if it works.
Before anything however, make sure you have a developer license like said on a previous post (no developer account is required. You don't have to pay for anything yet).
I'll try to provide step-by-step guid to fix the issue.
Please create an MSDN account here https://msdn.microsoft.com and use your login credentials in VS 2013
You have to enable "Developer mode" option from UPDATE & SECURITY (Windows 10). Attaching the screen shot for more clarity.
This should solve the problem, but if it doesn't then,
Try restarting your Visual Studio as administrator.
