Visual Studio File Conversion Fails - c#

I am trying to open this project in VS 2010. However, it fails, and I am unable to open the project. Why could this be happening?
The project is XNA.
Here is an error message:
The project file 'ShipDemo.csproj'
cannot be opened. The project type is
not supported by this installation.

XNA Game Studio is built upon Visual Studio 2008. They have not updated it to work with VS 2010 at this point.
In order to use XNA, you still need to work in VS 2008.

the issue i am having is, on a project i've been working on for a week, ONLY IN VS 2017, it now is unsupported. this is the error code i am getting:
Unsupported

No changes required
These projects can be opened in Visual Studio 2015, Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1 without changing them.
- MyProjectTitle, "C:\Users\meAsAUser\Desktop\MyProjectTitle\MyProjectSolution.sln"
I have gone through and deleted all .user files, tried cloning from my remote repo, opened the sln in notepad to make sure it was any CPU (it is), and restarted both VS and my computer.
it has now put the little "15" marker on all the solutions on my computer, which means this will be an issue for my other projects as well.

Export project from Unity to Visual Studio

Can I export a project done in Unity to Microsoft Visual Studio?
I tried selecting my project from menu Preferences->External Script Editor->Microsoft Visual Studio, but when I run the application, I get this error:
A project with an Output type of Class Library cannot be started directly
Have I done something wrong? If so, what?
Microsoft have now acquired UnityVS company SyntaxTree, and are offering the UnityVS plugin for free for Visual Studio 2010-2013 Professional or higher. This should allow you to run Unity projects from within Visual Studio.
You can download it here, or get it from the Visual Studio Extensions Gallery.

Working with Unity3D and Visual Studio 2013

how do i get Unity3D for debugging the code, and Visual Studio 2013 which i have now to only script the code. Example: Like Flash Professional for debugging and FlashDevelop for scripting only.
My question is, how do i get the Unity3D link with Visual Studio 2013. I already searching around the internet, and had found that Unity3D only works with VisualStudio 2010.
I wrote a blog article on this awhile back on my blog HERE for Visual Studio.
However I will paste it here too:
How to use Visual Studio 2013
Recently Microsoft bought and re-released the popular Unity3D plugin UnityVS. The now renamed Visual Studio Tools for Unity plugin smooths the connection between Unity and Visual Studio and even allows one to perform debugging too! Download it here.
In Unity Editor go to Edit->Preferences->External Tools and In External Script Editor choose Browse from the drop down box.
Browse to and select C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe.
The External Script Editor should automatically show your selected editor as Visual Studio 2013.
That’s it! It should just work from that point on.
As an important update, I would like to notice, that former UnityVS (after Microsoft's acquisition of SyntaxTree) is now available for free as a rebranded Visual Studio 2013 Tools for Unity.
The versions for VS 2012 and VS 2010 are also available.
The integration of Unity3d and Visual Studio got simpler with latest Unity (version 5) and Visual Studio Tools. This is the current procedure.
To use Visual Studio as editor and debugger with Unity you must:
Install the Visual Studio Tools For Unity. For this download the package at http://unityvs.com (careful to get the version for the Visual Studio you are using) and import it (as is standard in Unity for packages) by going into Assets -> Import Package -> Custom Package and browse to the tools installation folder and pick the package.
Once installed in Unity you will get an additional menu Visual Studio Tools, go there and select "generate project files". Visual Studio will already be the default editor for your scripts.
This done, if you say put a breakpoint in Visual Studio, click on "Attach to Unity" in Visual Studio, and then run your Unity project, the process will stop at breakpoints in Visual Studio and allow variable inspection etc.
you can use unityvs VS plugin (but I'm not sure about current 2013 support, it's works with vs2012) http://unityvs.com/ - on windows it's works very well, but remote OSX debugging feature is not ready yet
I'd like to add to the fine answer given by Pietro Polsinelli, that for me, there was an extra step in his Step 1. And that is that, after installing Visual Studio Tools For Unity, I had to, in Unity, go to Assets->Import Package->Visual Studio 201X Tools and then click around on the menu bar until "Visual Studio Tools" showed up as an option. After that, I could Generate Project Files and Open in Visual Studio.
This enabled me to Attach to Unity in Visual Studio and debug.
None of these solutions worked for me. Renaming monodevelop just changed the default program to notepad++, and the next default program after that was simply notepad.
However, there is a known bug with Visual Studio 2013 (not sure if it was present in previous versions, or if it is present in the non-professional version) where if you try to open a C# file in visual studio, where Visual Studio is opened as administrator and Unity isn't, VS crashes.
I had to either run both programs (VS and Unity) as administrator, or not open VS as administrator (as per the solution found here: http://connect.microsoft.com/VisualStudio/feedback/details/597863/cannot-open-visual-studio-files-from-windows-explorer).
With Visual Studio You Can Use UnityVS Plugin But if You Use Monodevelop You Can Go To Run->Attach To Process.. And Connect The Debugger to Unity Editor It Work Perfectly.
To link Unity with Visual Studio, do the following:
Do this on Unity.
Go to file --> preferences --> external tools --> external script editor --> Choose visual studio.
If Visual Studio is not showing, you Re gonna have to browse Visual Studio by hand.
Then you open any script in the Unity Project window and Visual Studio should open the file.
I hope this is helpful.
Note that I am using Unity 2020.2 and Visual Studio 2019

Not able to open vs2008 project in vs2010

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.
