I just did a fresh install of visual studio community edition.
When I start a new project and choose 'Blank App (Universal Windows)' I get this error during project creation:
Package Installation Error
Could not add all required packages to the project. The following packages failed to install from 'C:\Program Files (x86)\Microsoft SDKs\NETCoreSDK':
Microsoft.NetCore.UniversalWindowsPlatform.5.0.0: Package restore failed. Rolling back package changes for 'AppTest'
Any ideas what the cause of this error can be?
I installed all the Universal Windows App Development Tools:
- Tools (1.3.2) and Windows 10 SDK (10.0.10586)
- Emulators for Windows 10 Mobile (10.0.10586)
- Windows 10 SDK (10.0.10240).
What am i missing. How can I solve this issue?
Sometimes nuget fails to install the UniversalWindowsPlatform package. Search for "Microsoft.NETCore.UniversalWindowsPlatform" nuget package and install it.
This is not an answer, I have the exact same issue and I have found other people with the same issue on the web, no one has come up with a solution yet.
This is upon creation of 'any' UWP project type, blank, templated, VB, C#.
This dialog pops up:
I have already found and tried all of the steps mentioned by Jay Zuo. This is actually for a slightly different issue, the dialog is exactly the same apart from the bit, where we have ': Package restore failed.'
They are getting ': Solution is not opened or not saved'
None of the steps on that post help resolve this issue.
I have tried restoring VS, Reinstalling the Windows 10 SDK, resetting VS using the various options to reset user data, environment etc, made sure the path to the SDK files exists.
Nothing has worked and my VS2015 Community is utterly useless right now for working on UWP projects. This is a new Windows 10 / VS install (VS on insider fast PC has no issue at all but I need this one on production build).
I am posting as an answer as I do not have enough points to comment but starting a new thread seems daft as this is the exact same issue, I just want to add more detail to it.
I had the same probem after a clean install of OS/Updates/VS 2015 Update 3 + Xamarin update. I created a Universal 'Blank XAML App (Xamarin Forms Portable)' During creation I received same error.
In the Nuget Package Manager Console pick AppX.UWP, then run:
Install-Package Microsoft.NETCore.UniversalWindowsPlatform
Restart VS and create a new project, error does not come back.
So after much back and forth between myself and an MS rep on their forums I did actually manage to resolve this.
The forum link is here
I did actually need to reset my VS installation to try and get a clean install.
Then the actual error reared its head. In my case it was Nuget caching corrupt packages (these are not cleaned by a VS reinstall).
The link that helped me resolve it in the end can be found here on Stack Overflow
What helped me was to update the UniversalWindowsPlatform package in nuget to 5.1.0. Then all went smoothly the next time I created UWP project.
Upgrading the package Microsoft.NetCore.UniversalWindowsPlatform.5.2.2 worked for me...
After facing a similar problem with Microsoft.NetCore.UniversalWindowsPlatform.5.2.3. I found a solution which might help someone. I navigated to my ProgramData\Microsoft\VisualStudio\Packages\Microsoft.Net.CoreUWP,version=1.0.4 and ran the netfx_NETCoreUWP.exe. It did resolve my problem
Just as a reference...
My NugetPackage "'Microsoft.NETCore.UniversalWindowsPlatform" disappeared from my project references. It showed up as installed in NuGet. I uninstalled and re-installed without success. I restarted Visual Studio and re-installed and the package reappeared :-) !
I am running Visual Studio 2015 under Windows 10.
I was able to successfully create and open Cordova projects, but suddenly one day I started receiving the following error message:
An equivalent project (a project with the same global properties and tools version) is already present in the project collection, with the path "{path-to-cordova-project}". To load an equivalent into this project collection, unload this project first.
When I go to modify the Visual Studio installation, I can see "HTML/JavaScript (Apache Cordova)" appearing twice in the list of features:
As you can see, there is a replaced version, and an Update 1.
I have tried every combination of uninstalling/installing each of Apache Cordova (Replaced) and (Update 1), and also Tools and Windows SDK 10.0.10240. I also tried deselecting/selecting to reinstall.
I managed to get it working once for creating new projects, but when I opened a project which failed to open before, it started failing again for creation and opening, and haven't been able to get it working again.
I tried completely uninstalling VS 3 times, once using the command G:\vs_professional.exe /uninstall /force
I also tried tried renaming C:\ProgramData\Package Cache folder before installing again.
But it seems to be leaving bytes somewhere, because after reinstalling I can still see the Recent projects, and project templates downloaded before uninstalling.
I am now going to consider formatting the partition and reinstall Windows, but this is very frustrating and disappointing.
I hope someone come up with a solution for this before I proceed to format.
Thanks.
PS: I think the latest thing I installed before this started to happen was ASP.NET 5 Beta 7. But I am not sure if this was the root cause of this problem.
Same problem with (Visual Studio Tools for Apache Cordova Update 1 + ASP.NET 5 beta 7). I resolved it by uninstalling beta 7 of ASP.NET 5 (uninstall explain here) and do a devenv.exe /resetuserdata
Fixed it uninstalling apache cordova tools and using the vs installer to install it again.
Also did removed AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache and devenev /resetuserdata
so that may be also needed, not sure.
Every time I right click the Controller folder and click add -> Controller, VS 2015 freezes. I am running on the latest win 10, VS is up to date and all the packages are the latest. I've tried different locations, checking permissions on the files and all types of other fun stuff. The weird part is that it only freezes on an azure mobile services project. If I do a web api project or mvc project I can add the controller just fine.
Any ideas?
I also was having this issue for a few days now and I just managed to solve it by re-installing the Entity Framework package using the nuget console:
Update-Package EntityFramework -reinstall
The above solution didn't solve my problem. Even reinstalling VS 2015 didn't.
But the running the following could solve my problem:
open administrative cmd in folder
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
devenv.exe /resetsettings
devenv.exe /resetuserdata
When I try to create a new Windows Forms project, I get the " ....csproj cannot be opened because its project type (.csproj) is not supported by this version of the application" error. The .csproj file it is referring to is in AppData\Local\temp\randomname\Applicationname.csproj but that file does not actually get created.
I know that when this error crops up with opening projects created in previous versions, it's usually a missing library that is used by that particular project but for the life of me, I cannot figure out what library I could be missing here as it is a new project.
I have VS 2013 Ultimate installed with all components.
Running on Windows 8.1.
First confirm it is not a add-on or a problem with Visual Studio itself.
Try and start Visual Studio from the command line with devenv.exe /resetskippkgs and also try disable any IDE extensions temporarily to see if one of them might be stepping on something. Do these two things first to see if the problem lies with VS IDE. Of course try creating a project after you have done these two things and see if you get the same results.
I never figured out what the actual problem was but I've installed Update 5 which was only released less than two weeks ago and it's working fine now.
I was getting the below message from Visual Studio 2010.
"This project is incompatible with the current version of Visual Studio"
One situation resulting in this error has already been posted here at Stackoverflow, but that question has been closed. I'm thinking it's a fairly generic problem. Since I have found a "solution", I'll post this question, and my solution as an answer.
If the message
This project is incompatible with the current version of Visual Studio
is due to an attempt to open a project targeting .Net 4.5, then the "solution" or workaround is to edit the .csproj file and change the TargetFrameworkVersion from "v4.5" to "v4.0". That at least allows the project to be loaded, although it may result in compiler errors if the program is dependent on 4.5 features.
VS 2012 has different project type support based on what you install at setup time and which edition you have. Certain options are available, e.g. web development tools, database development tools, etc. So if you're trying to open a web project but the web development tools weren't installed, it complains with this message.
This can happen if you create the project on another machine and try to open it on a new one. I figured it out trying to open an MVC project after I accidentally uninstalled the web tools.
I just got the same error message with a couple projects after installing Visual Studio 2015 Update 3. For me, the solution was to install .NET Core
In my case it was an incompatible Project Type. Editing project file and removing ProjectTypeGuids node resolved the issue of loading the project (I had already re-targeted the framework version as advised here).
Probably the project type is not supported in the (most likely) NEW version of VS, so you will have to adjust (update) the code to work properly (if possible), but at least you can see the content through VS.
I Resolved the issue by deleting the files in the below folder
%localappdata%\Microsoft\VisualStudio\12.0\ComponentModelCache
Source: https://forums.xamarin.com/discussion/70388/how-to-fix-incompatible-issue-after-visual-studio-2015-update-3
As for me, I realized there was another web project in the solution that my VS2017 was loading fine, so I copied over the ProjectTypeGuids element of it over to the project that wasn't loading. Its diff was:
- <ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
+ <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
After this, it loads. Don't ask me why.
If you are getting the same error for a project which is actually an extension (.vsix), installing Microsoft Visual Studio 2012 SDK does the trick.
Go to tools -> Extensions and updates -> Online -> Search for project installer -> download
And relaunch Visual studio.
After installing Update 3 for Visual Studio 2015, I suddenly got the "This project is incompatible with the current version of Visual Studio" error message while opening my Cordova project (.jsproj Javascript project file)
To solve this:
Go to Programs & Features
Select the Microsoft Visual Studio 2015 installation and click Change
Click Modify
Install "HTML/Javascript (Apache Cordova) Update 10" of the Cross Platform Mobile Development section
For me, I got this same error in VS 2015 and just installed the VS 2015 update 1, though from another answer, VS is actually up to Update 3, now (after which, they got the error and had to install .NET Core). Had issues when it hit certain packages, like the Windows SDK ones, and had to point the installer back at the paths in my original CD, and for some, even that didn't work and had to skip them and re-download from an internet-connected computer, transfer them over, and run them later manually (computer was not connected to the internet to be able to download updated versions of the packages), but after doing all that and doing a reboot, the error was gone and my project loaded fine.
I had this issue and after hours of uninstalling and reinstalling I found out the issue in my instance.
The reason why I got this was down to the fact that I didn't have the correct extension.
In my case the ASP.net project (my startup) was the incompatible project and this was because I didn't have the following:
Microsoft ASP.NET and Web Tools
Micrsoft ASP.NET Web Frameworks and Tools
It was a simple case of going into extensions and updates under the Tools menu
I had this error and found it was due to the presence an 'Import' XML tag inside the .csproj.user file. Once I removed it, Visual Studio could open the project again.
What most people forget it is that the files of visual studio are just text files, that have some peculiars configurations that will show to the program how to open it. that is, we can change this because it's just a text in some file in there in your project folders.
Well, knowing this, what we have to do is very simple!
The first step is knowing what kind of project it is this project that stay unload. (for example: Class Library)
The Second step is create a new one (Class Library) because you know that your visual studio will create a version supported by himself. Unload this one and click in "Edit csproj".
It's in this file that we can found the configuration that tell to VS how this proj will be loaded and his name is ProjectGuid, this serial number has a variation according the type and version of project.
Now, look at your "ok project", copy the "ProjectGuid" TAG, paste on csproj that unloaded, and pay attention to the little differences and make this files almost equals, except for the tags ItemGroup that represent the references of the project.
Doing that, save all files and close your VS and open again, now your project should load normally.
I hope that this informations help somebody to understand a bit more how the VS works and help solve the problems when necessary.
I checked if i could create a new solution and was unable because SSAS,SSIS and SSRS weren't there as options.
I downloaded SSDT from here and installed and it worked...
https://learn.microsoft.com/en-us/sql/ssdt/download-sql-server-data-tools-ssdt?view=sql-server-2017
In case you came here looking for the issue with ".smproj" file, it is because you are missing SQL Server Analysis Services(SSAS). To over come this, install SQL Server Data Tools(SSDT) in your system, restart your Visual Studio and it will work.
Thanks.
This is my answer, I think it's useful. Please follow below steps:
1.First check your Visual studio version is 2012, 2015 or 2017 etc.
2.Your project is developed in 2015, but your visual studio 2012, then visual studio 2012 should not open the which are developed in visual studio 2015 projects.
3.If developed project visual studio 2012 and you have visual studio 2012, open the project but here need to check one option as per below
a) Target Framework - Open your project ".csproj" file with notepad++ and search with "TargetFrameworkVersion" and observe target framework value.
b) Open any existing project in your visual studio - Select project at 'Solution Explorer' - Right click - Properties - Application -Select Target Framework - Observe highest your framework which you have
c) 3.a and 3.b frameworks both are should same otherwise applications are not open
d)If your target framework less than the project framework should install the latest's
e) above options do not work just Simply have another option modify the "TargetFrameworkVersion" value in '.csproj' file which is have in your visual studio.
Ex: in my visual studio target framework 4.0 but in '.csproj' file have TargetFrameworkVersion - 4.5, You need just change 4.5 to 4.0 and open the project
This issue might be caused when using VS 2015 with Update 3 installed on one PC and without update 3 installed on another. This was the problem in my case.
