I am trying to open a solution that involves an MVC project in Visual Studio that was developed in VS 2010. After I open the solution, I get this error:
Unsupported
This version of Visual Studio is unable to open the following projects. The project types
may not be installed or this version of Visual Studio may not support them.
For more information on enabling these project types or otherwise migrating your assets,
please see the details in the "Migration Report" displayed after clicking OK.
The migration report contains this message:
The application which this project type is based on was not found.
Please try this link for further information:
http://go.microsoft.com/fwlink/?LinkID=299083&projecttype=F85E285D-A4E0-4152-9332-AB1D724D3325
I tried the following approaches (in no particular order)
Repair VS
Run devenv /Setup in the solution directory
Delete the .user file associated with the project
Repeat of all of those steps after rebooting my computer
Install MVC 3 and create an MVC project as described in the link in the migration report. Here, the described files (e.g /Views/Web.config) don't seem to exist.
What changes do I need to make to make the MVC project compatible?
Not sure what code/config files I would need for this, but please comment on any further info that could be helpful.
I am trying to create web application using Visual Studio 2015 and .NET 4.5.1.
When I publish the website, visual studio create folder named roslyn.
I know it's used to compile code on the fly, but unfortunately my hosting provider doesn't allow me to execute the compiler on their server.
How to publish the website without roslyn like previous version of Visual Studio?
EDIT:
I got this error when trying to acces my website.
It seems IIS trying to execute roslyn\csc.exe but my user account doesn't have permission to do that. With previous version of Visual Studio, this error doesn't show up.
I've just faced the same problem. When you create a new web project, two nuget packages automatically added to your project. If you remove them, your problem should be solved. Package names are: "Microsoft.CodeDom.Providers.DotNetCompilerPlatform" and "Microsoft.Net.Compilers".
I had the same issue. Followed the steps from here. Basically:
Uninstall the package
Uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform <Your Web API project name>
In your publish profile settings, uncheck "Allow precompiled site to be updatable". You can find this under Settings > Precompile during publishing > configure
After searching the same issued I face, I just came here. I read the above answer which is right.
I give the answer, because of Here is the good article to explain :
Why the publish code have this exe as well as development environment ?
What is the benefit and how to remove?
This is also the very good article, about the history of this exe
After countless effort....and according to this website.
I find that you can use /p:UseWPP_CopyWebApplication=true /p:PipelineDependsOnBuild=false in MSBuild to transform web.config, this also include the roslyn compiler in the build. The output is same as what you get by publishing in Visual Studio into file system
There is an open bug on the roslyn repository about this issue.
In my case all I had to do was to downgrade the dll Microsoft.CodeDom.Providers.DotNetCompilerPlatform from version 1.0.6 to 1.0.5.
I have had the same issue in Sept2016 when I took over an existing ASP.NET program. I found that there were multiple versions of the two compiler packages mentioned by Kemal installed in different projects of the solution.
So firstly I updated to get them the same. VS doesn't tell you that updates are available in this scenario (or maybe I missed them ?)
I then had to restart VS2015 for the packages to clean up properly.
Looked through some similar questions, could not find one that fits my case.
I have a solution that I created some time ago in VS 2010 (maybe originally in MVC2), and eventually upgraded to MVC4.
The solution works properly when opened with VS 2010, builds and runs - everything as expected.
To confirm that I use MVC4, I checked the properties of my System.Web.Mvc.dll. It appears to be 4.0.0.0
From this I assume that I have MVC4 successfully installed on the machine.
However, when I try to open the solution with VS 2012 I get the following infamous error
Full text:
Unsupported This version of Visual Studio does not have the following
project types installed or does not support them. You can still open
these projects in the version of Visual Studio in which they were
originally created.
- Recipes, "C:\ ... Copy\Recipes\Recipes.csproj"
I can also create a new MVC4 project using VS 2012, so I'm assuming I don't lack any tools VS 2012 needs.
What else could be the problem?
There's probably an entry in the <ProjectTypeGuids> element of the .csproj file that VS2012 doesn't recognize. I have a vague recollection there was some tooling identifier change but I can't recall specifically.
My suggestion would be to create a new project from scratch and then compare the <ProjectTypeGuids> elements in each .csproj file to try to figure out which one from the VS2010 project it doesn't like in VS2012. It's likely going to require some trial-and-error tweaking of the list so make a backup of the file first so you don't get yourself into a situation where you can't open it at all.
If you don't want to take that approach another option would be to create a new empty project and then import the individual files from the old project into the new, but that could obviously be quite time-consuming if it's a large project.
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.
When I open a particular mvc 3 website project in VS 2010 I get the following message:
The Web Project "X" requires missing web components to run with Visual Studio. Would you like to download and install them using the Web Platform Installer now?
ASP.NET Web pages with Razor syntax.
When I click yes
The web platform installer shows with the message that "0" items need to be installed.
My other mvc 3 projects do not show this behavior
Not a major inconvenience, but still...
thoughts any one?
I got the same error after reinstalling my computer.
I came to this conclusion, VS needs IISExpress to load my additional project. The addition projects has a webservice and it can run locally. Even if my endpoints points to a local address it still needs the IISExpress (standard IIS 7.5 does not respond the endpoint request) to open from VS (im running VS2010).
So after installing IISExpress i could reload my project in VS.
C.,
That shouldn't happen, and it would be interesting to figure out why. In the meantime, you should be able to turn this off by unchecking the "Package Restore" checkbox in Visual Studio's Options dialog. (Select "Package Manager" in the tree view to find it.)
If it's happening only for specific projects, you can solve this more surgically by removing the packages.config file for the affected project. In fact, if you want to do root cause analysis, you should look into why that file exists and how it got there.
HTH,
