I have project files created with MVC3, C#, VSE 2010 web developer.
Just installed the latest VSE 2010 web developer.
When I try to open .sln file I got the following message:
D:\Work\tech_descr\Site\Site.csproj : error : The project file 'D:\Work\tech_descr\Site\Site.csproj' cannot be opened.
The project type is not supported by this installation.
I checked proposed solutions from forum, but it doesn't work. Looks like my versions of software are fine.
here are strings from csproj:
<ProjectGuid>{9F99CE4B-6664-401C-AEFD-DD53C3281B42}</ProjectGuid>
<ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
Dont double click .sln file to open solution,open it form File->Open menu from VSE 2010 it will prompt you to convert
I would start by reinstalling MVC 3.
As an interesting note, those guids are, respectively:
Visual C#
Windows (C#)
Web Application

I have a problem with publishing an app in VS 2017 with the Publishing Wizard. I found a stackoverflow post:
Compile a .NET Core application as an EXE file using Visual Studio 2017
But when I want to go to this menu it only opens an old Publishing Wizard that doesnt have the options I need.
I tried to update my VS 2017 to the newest Version, but it didnt help...
After that I tried to use the first approach of the stackoverflow post above, but I didnt have dotnet(???) so installed .NET 7 SDK. Tried the command in the project directory (where the .csproject lays), but I got the error: MSB4062. So Im back trying to get the new publisher, because I really dont know how to fix MSB4062.

The Publish Wizard is usually the first time you publish a project and will guide you to publish the project to the specified location.
After completing the Publish Wizard, you will find Publish Settings in the Publish view and configure it. Hope it can help you
I needed a .NET Core / .NET console app, but I had a .NET FRAMEWORK console app.
And to create a .NET Core / .NET console app I needed Visual Studio 2022 (maybe 2019 is enough), but I had Visual Studio 2017.
This fixed everything for me.
When I create a Xamarin.Forms application using Visual Studio Community 2015 Community on Windows 8.1 it shows me this error on load:
A problem was encountered creating the sub project 'App1.WinPhone'. This project requires a Visual Studio update to load. Right-click on the project and choose 'Download Update'
I've installed all updates available and trying on a newly installed Windows.
Note: I had this error in Forms.
How can I fix this error?
Note: There isn't a Download Update option in Solution Explorer.
Navigate to where you saved the project files that you created in Visual Studio. Default location is C:\Users\PSDan\Documents\Visual Studio 2015\Projects.
Open the project folder that you are experiencing problems with and navigate to C:\Users\PSDan\Documents\Visual Studio 2015\Projects\test\test\test.Windows folder. Inside this folder is a file called test.Windows.csproj.
Right click on that file and open with... using Visual Studio, by doing this it should detect the missing package and in my case automatically prompted to install the missing package.
I've been seeing similar errors for .Window or .WindowPhone and what I've observed is that it is due to missing SDK. Same might be the case with you.
Do you see App1.Droid appearing in the solution? (I guess NO)
Go to file explorer and locate App1.Droid.csproj (..\App1\App1.Droid\App1.Droid.csproj) and open this in a new instance. There it will pop up "Install Missing Feature" dialog and you can follow the steps to install missing components.
If your issue is the same as here:
Project required a Visual Studio update
then you may try and see if this solution works:
[Cause is] a mismatch of the target framework version and profile in the .csproj file. Despite the target framework being correct in the project Properties, they were not being correctly saved for whatever reason. Thus, when trying to install a utility library from nuGet, it left my project in the state you described.
The solution was to go by this site:
Framework Profiles in .NET
and find the correct combination, then manually edit the .csproj file to adjust <TargetFrameworkProfile> and <TargetFrameworkVersion>.
Installing Visual Studio Update 3 with selected features "Windows 8.1 and Windows Phone 8.0/8.1" and "Cross Platform Mobile Development" solved the problem for me.
Uninstall Xamarin completely, and reinstall it. That happened to me as well. I would uninstall Visual studio too. Install that first, then install Xamarin.
Edit: I know this sucks to do, but it was what the Xamarin team had me do to resolve it. As far as I know this is the official fix as of last week.
My colleague sent me a web project written in Visual Studio 2010. I only have Sharp Develop. when I open the project, I get a number of error messages:
The imported project "c:\program files(x86)\MsBuild\Microsoft\VisualStudio\v10.0\WebApplication\Microsoft.WebApploication.targets" was not found. Confirm that the path....
See:
What do I need to do to fix this??
Download and install the Visual Web Developer Express 2010, it should install all the required libraries to your system. You can then use Visual Web Express to edit the solution, but chances are high that Sharp Develop will also be able to open it.
If you want a little more up-to-date editing experience, you can try upgrading the solution to Visual Studio Express for Web 2013 by installing that and resolving any upgrade issues that might come from that.
I've created a game for an assignment in Visual Studio 2012 and the university I'm at uses 2010 and it won't open! It mentions something about NET Framework 4.5. How can I convert my project so it will open in 2010?
It takes three step:
Step 1
Open solution file (.sln) in a text editor and change
Microsoft Visual Studio Solution File, Format Version 12.00
to
Microsoft Visual Studio Solution File, Format Version 11.00
Step 2
Open application configuration file (App.config) in a text editor and change
sku=".NETFramework,Version=v4.5"
to
sku=".NETFramework,Version=v4.0"
Step 3
Open project file (for C# language .csproj) in a text editor and change
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
to
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
Now enjoy your project in VS 2010 !
You may only need to open the project in Visual Studio 2012, and go to the project's properties page.
On the Application tab, locate the Target Framework setting, and change it to .Net Framework 4.
After that, you should be able to open it in Visual Studio 2010.
Also see Converting VS2012 Solution to VS2010, but so far I haven't had to do any conversions on VS2012-created projects to open them ins VS2010 - but YMMV.
[EDIT]
I just tested this again (to be sure) by creating a .Net 4.5 project in VS2012, and verified that I couldn't open it in VS2010. Then I opened it in VS2012 again and changed the framework version to .Net 4.0. After that I could open it in VS2010.
Note that I didn't have to make any other changes. However, this is on a computer with VS2010 and VS2012 installed, so it's possible that installing VS2012 might do something with VS2010 to make it work...
I have done this at work
Open .sln file with notepad
Change the two lines below
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2012
To
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio 2010
and hey presto the solution now opens in VS2010
You can create a new project in Visual Studio 2010 and then right click in the solution explorer > Add > Existing item. To pull through all of files in your 2012 project.
Either create a new solution in VS2010 and add all existing files from your VS2012 or compare the .sln file to a .sln file freshly created with VS2010. At the top you'll see some version information that should be changed. Also compare the .csproj files and change any version information accordingly and the target framework.
Missing library or framework could also cause this problem. For example, if you want to open a MVC4 or Silver Light project but you don't have these libraries installed at your PC.
Open .sln file and Change Format Version to 12.0 to 11.0
I am trying to open a project developed in vs2008 but i am getting the following error.
"cannot be opened because its project type .csproj is not supported by this version of the application".
And I tried by selecting open with-> visual studio version selector but it opens as a vs2010 project and gives the same error.
When I got this msg, it was because I was opening a "non native" project format. Like e. g. MVC. You would have to install that project-type-extension (if that is the correct name? the one that gives you the project template) for VS2010 as well. I think it even needs to be same version.. like MVC2 again instead of MVC3.
Similar with XNA.
Thanks to all of you for your kind help.
I was working on a project and it was in vs 2010, same time i tried to open another project for reference which was in vs 2008, even i opened in new instance it was unable to open that.
At end I closed all the VS instances and opened vs 2008 project first, then it asked for version specification.
Did'nt able to rectify the error but got the solution.
"First close all the opened instances and then open the older one".
Just try to open the solution file in an text editor and change the
# Visual Studio 2008
to
# Visual Studio 2010
Does it help?
PS: Here are the differences between VS 2008 and VS 2010 sln and csproj files listed:

You can try to port manually. Just make a backup before you do.
