I am getting the following exception while adding NuGet package to project. I am using the latest version of Visual Studio 2017 Pro.
try going to VS settings -> NuGet settings -> clear the NuGet cache, close Visual Studio, and delete all obj and bin folders in solutions .
Error while adding NuGet Package
AFAIK, It seems an issue which needs to be fixed from Xamarin team and someone already reported it:
https://bugzilla.xamarin.com/show_bug.cgi?id=61113
You can track this thread to get future updates for this issue.
Here are some of the workarounds already mentioned in that thread:
Update the packages with the option -IgnoreDependencies in the Package Manager Console (It works for me):
Update-Package -IgnoreDependencies
Update Visual Studio to latest version and running as Administrator
Some of the files in the packages folder were set to read-only. Try to cleare the read-only flag from all files in the packages folder.
Hope this helps.
I tried a lot of ways to solve this problem. But unfortunately cleaning the cache, project, rebuilding didn't help. The only thing I didn't try is to re-install Visual Studio or Windows.
I've got to launch project in Visual Studio for Mac and update/add all the necessary Nuget packages from there. On the Mac, the process was successful. I know this might not be an option if you don't have device, but it definitely works.
I'm using the built-in Visual Studio test tools (Test -> Run -> etc in the menu). I just started having a problem where I get the following error when I try to run tests
[3/29/2018 1:39:14 PM Error] System.IO.FileNotFoundException: C:\Users\brubin\AppData\Local\Temp\VisualStudioTestExplorerExtensions\MSTest.TestAdapter.1.1.18/build/_common/Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll
at Microsoft.VisualStudio.TestWindow.Controller.TestPlatformProvider.PerformShadowCopy(IEnumerable'1 testExtensions)
That's followed by some errors that say
Make sure that test discoverer & executors are registered and platform & framework version settings are appropriate and try again.
When I look at the folder C:\Users\brubin\AppData\Local\Temp\VisualStudioTestExplorerExtensions\MSTest.TestAdapter.1.1.18/build/_common/, there are no files in that folder. However, I haven't knowingly changed anything about my test setup and this was working several days ago, so I don't know why it would have stopped working.
My projects are using the MSTest.TestFramework (MSTest V2) version v1.2 NuGet package.
One thing I noticed that may have caused this problem is that if I go to Tools -> Extensions and Updates, I see that my Microsoft Visual Studio Test Platform was updated a few days ago, on 3/23 (I think that's when I installed a Visual Studio update). However, if that broke something, I have no idea where to look to see what's broken, or how to fix it.
For me, clearing the VisualStudioTestExplorerExtensions folder and restarting Visual Studio (as per this github issue) did the trick. In my case, it contained two folders for different versions of MSTest.TestAdapter, I don't know whether or not that's relevant.
For anyone else who stumbles on this question, the problem was caused because a few of my test projects didn't have the MSTest.TestAdapter NuGet package included. I added the MSTest.TestAdapter package to all of my test projects, and the problem seems to be solved permanently now.
I spent the whole last week trying to solve the same issue. Only yesterday did I realize that running tests from the console is a time saver. Much to my surprise, I've just moved all my project -which was inside a "OneDrive" folder, to a different location. Now, it works like a charm! All my tests run from the Visual Studio IDE. I don't know if moving the files had anything to do with it, but you can give it a try.
Reinstalling all solution's Nuget packages fixed this issue for me.
Please run this command on the package console:
Update-Package -reinstall
then try again, or restart VS, then try again.

Its a bug in Visual Studio. Upgrade the Visual Studio to version 15.7.

Yes you need to update "MsTest.TestAdapter" on all testprojects. The easiest way is to rightclick on master solution and click on manage nuget-packages. Then select " installed " tab and see if there is installed TestAdapter on each testprojects. If necessary you can update TestAdapter to newest version. Then restart Visual Studio and it should work.
It's very possible that I'm missing something simple because I can't find others on the internet experiencing the same thing.
I'm a team that's new to the use of TFS and Visual Studio Online and we're encountering this problem:
(Using Visual Studio 2015 & 2013)
I used NuGet to add Microsoft.AspNet.WebApi.Cors to my newly created WebAPI project (ditto all other NuGet packages)
Did my work and checked in a building solution in to VSO
Co-worker did a Get Latest
His newly-retrieved project won't build and, when we expand the References, the assemblies are marked with a yellow warning icon, indicating that they're missing
We've tried (from the context of the failing project):
Update-Package
Update-Package -reinstall
Manually uninstalling and reinstalling the package in the NuGet UI
Manually adding the entire contents of the Packages directory in to TFS and doing a get latest on that directory as well
Wiping the solution out from his local file system and pulling it down clean
Copying the contents of my {Solution Directory}\Packages to a USB drive, walking it to my co-worker's computer, and copying it to his machine
Only item #6 worked but I'm CERTAIN that this cannot be the right answer.
I guarantee that this is worthy of a dope-slap but what might I be missing?
Thank you to jessehouwing for reminding me that this topic is still out here. He's exactly right on. We removed the Packages folder from source control and that resolved the problem completely.
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.
