Visual Studio 2005: Project file can not be opened - visual-studio-2005

I have a big solution file and few projects can not be loaded. I do have all the files in the proper directories. But when I right click and try to load the project, I get the following error:
The project file "C:\myapp.proj" can not be opened. The project type is not supported by this installation.
By the way, these projects are related to Windows Workflow.
Please help.
I am using Visual Studio 2005 on Win7 machine.

It might be a modeling project, test project, silverlight/wpf project etc. It's definetely something that's not supported by your version of Visual Studio, you should use a newer version or a different one (i.e. professional instead of express).
Update: I did not see that it was Windows Workflow Foundation. Check out this link, it's a toolkit for using Workflows in VS2005.

Will visual studio 2015 projects and solutions be backward compatible with 2013?

Now that Visual Studio 2015 RC is out, has anyone installed it and opened Visual Studio 2013 projects/solutions?
Does it ask the files to be changed?
If yes, are the changes it makes backward compatible?
Take a look at the Porting, Migrating, and Upgrading Visual Studio Projects article for Visual Studio 2015. All of the various caveats are described there.
Not all types of project are supported. I tried the following 4 project types:
Vb.net Class project, OK.
Vb.net Web Services project, OK.
Cordova JS project, not OK, need to migrate manually, by moving the sources from root directory to the www directory and install all API again.
C#.net winform project, OK.
Yes, though you sometimes will have to change the version (single number) in .sln file, no other differences found yet.
We resolved this by typically excluding this file from check in and only check it in when there really was a change (added project, ...) - and then to fix the version before checking in. (Different developer machines with different versions of VS.)
See question Visual Studio 2015 solutions backwards compatibility with Visual Studio 2013 and answer https://stackoverflow.com/a/31540590/586754.
(Assuming you are having basic projects that are supported by both versions, like C# and .net framework that is supported by lower version VS.)

SharePoint Deployment from Visual Studio 2010 Location

So I have a web application in visual studio. I can right click on the project and click Deploy which will send the files live to the SharePoint server.
I accidentally reverted one of the pages to an older version in Visual Studio and was wondering if it's possible to get the version running live on the SharePoint server as that is the latest version.
I cannot currently deploy as this will then run and old version of the page I accidental reverted.
Where would the files be stored and how could I find them? visual Studio is running on the SharePoint server.
Thank you very much!
Visual Studio does compile your *.aspx.cs files to the *.dll file of your Solution/Project.
If you want to get the code of your old *.aspx.cs file you can use Reflector or ILSpy to decompile your *.dll (actually deployed to your SharePoint) and find the old code by namespace.

Convert solution to the latest version

I am practicing Microsoft net framework training kit. The problem is that the solution/projects were made by Visual Studio 2008. I use Visual Studio 2012.
The projects are unavailable.
I want to modify the solution file and project files. Just worry about messing up them.
Another snapshot:
How to modify them by editor then I can load them with visual studio 2012?
Visual Studio should do update the projects and solutions for you. In my experience, it only shows unavailable when the project is located in a different location than where the solution file is looking for it. Perhaps you recently changed the name or copied only some of the files?
At the very least you should be able to remove the unavailable projects and re-add the original projects. They'll be converted as they're added.
Convert it to 2010 first, then convert it to 2012. It is the particular case. It could be the project was written in 2008 but faied in 2012.

How to choose Visual Studio solution Platform Toolset for maximum compatibility

Background
I am open sourcing a few old Visual Studio applications I created a while back. I have created new solutions using my new VS2012 environment for them and have gotten the projects set up as git repositories. I got everything working fine in Visual Studio 2012 with no changes to the source code, all I needed to do was make sure I was linking the proper libraries in the new project configurations.
I would like to configure these projects as to have maximum compatibility for others downloading the project from Github. On this machine I have VS2010 installed alongside the latest VS2012 version. After I got everything working right for both of the projects in VS2012, I tried to open them up in VS2010.
When I tried to build I got a single error:
Specified platform toolset (v110) is not installed or invalid.
Please make sure that a supported PlatformToolset value is selected.
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\Microsoft.Cpp.Win32.Targets 518
What I Tried
So I opened up the properties for the project, went to Configuration Options --> General and the Platform Toolset was indeed set to Visual Studio 2012 (v110). This input is a drop down box and the v110 value is not listed, instead I get two choices:
v100
v90
These correspond to VS2010 and VS2008 respectively. If I change the value to v100 and rebuild I get no errors and my program runs just fine in my Visual Studio 2010 environment.
When I open the project back up in Visual Studio 2012, if tells me that I have an old project file and asks if I want to upgrade, I say yes and it upgrades. I rebuild and run to make sure everything is still working. When I open the configuration options in VS2012 the Platform Toolset is set back to `Visual Studio 2012 (v110) but clicking the drop down input there are several more choices listed:
Visual Studio 2012 (v110)
v110_wp80
Visual Studio 2012 - Windows XP (v110_xp)
Visual Studio 2010 (v100)
Visual Studio 2008 (v90)
‹inherit from parent or project defaults›
My Questions
This has led me to several questions. I am going to pose them all. It would be nice to get as much information as I can, but a good answer to just one of them would probably solve my problem.
If I'm not using features specific to newer versions of Visual Studio, is it possible to set up a solution which can be opened and run without modification in as many versions as possible (ie. 2008, 2010, or 2012)? If so, how?
If I set the Platform Toolset to v90 (VS2008) from within Visual Studio 2012, and it's able to build and run, does this mean that it will build and run for users with VS2012, VS2010, and VS2008?
What exactly does the <inherit for parent or project defaults> option do? What would the project defaults be set up as? Can this be used to tell Visual Studio to try to using whichever installed Platform Toolset will work.
Are there any other options besides Platform Toolset in Visual Studio that I can set to increase compatibility with others' development environments?
This is a somewhat tricky situation. One of the underlying problems here is that VS2010 and VS2012 use MSBuild to build C++ projects, but VS2008 farmed it out to VCBuild instead. You can see this by comparing the project files. VS2010/VS2012 use .vcxproj, while VS2008 uses .vcproj.
If I'm not using features specific to newer versions of Visual Studio,
is it possible to set up a solution which can be opened and run
without modification in as many versions as possible (ie. 2008, 2010,
or 2012)? If so, how?
For maximum compatibility, you want to target the lowest common denominator (i.e. vc90 in this case). Note that when you do the upgrade, the solution file and project files get upgraded to the latest version, which may break compatibility with older versions of Visual Studio.
If I set the Platform Toolset to v90 (VS2008) from within Visual
Studio 2012, and it's able to build and run, does this mean that it
will build and run for users with VS2012, VS2010, and VS2008?
Not really, due to the .vcxproj / .vcproj conflict stated above.
For example, I currently have a set of .vcxproj files and a solution designed for VS2010. I use VS2012 as my IDE, so when I open the VS2010 solution in VS2012, I choose to NOT upgrade it and simply open it as is. VS2012 and beyond should be backwards compatible back to VS2010 as far as project files go.
For maximum compatibility in development environments, my recommendation would be use VS2010's solution as the baseline, targeting v100. Developers can use any version newer than that and it should all work together gracefully.

The error "This project is incompatible with the current version of visual studio" displayed

I installed Vs 2010 Express in my PC, and created a poject named myproject with .net 4.0, it works well in Vs 2010 Express.
Now I installed Vs 2012 Express in my PC, and open the project myproject and upgrade it to .net 4.5, it wells well in Vs 2012 Express too.
I delete the project myproject all files, then restore it from my old backup file, when I try to open the project from Vs 2010 Express, I get the following information.
"This project is incompatible with the current version of visual studio", why?
How can I open the project in Vs 2010 Express? I guess the Vs 2012 Express maybe mark the project as .net 4.5 and stored the information in the somewhere of hard drive. Although I restore the project myproject from old backup file, Vs 2010 Express still think it is a project of .net 4.5.
Thanks!
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 with Visual Studio 2010, 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.
I know this is a little old, but just in case the above solutions don't work: don't be an idiot like me and try to open an MVC project using "VS for Desktop" instead of "VS for Web" (or vice-versa), since it will give you the incompatible message.
I use TFS at my job and I tried to open a MVC project via the TFS Solution Explorer. I wasn't paying attention to which Visual Studio version I had open and since both IDE's look alike, I was confused at what was going on - a common mistake, I'm sure =P
If you are getting the same error for a project which is actually an extension (.vsix), please install Microsoft Visual Studio 2012 SDK
Installing KB2781514 - Update for Microsoft Visual Studio 2012 solved the problem for me.
Check the directory that contains the solution file for an UpgradeLog.htm file. It will probably show what's wrong. In my case I tried to open an ASP.NET project, but the Web Developer Tools were not installed.
The Web Developer Tools can be installed afterwards by going to the Control Panel and to modify your existing Visual Studio installation. After adding Web Developer Tools the project opened without issues.
In my case the problem was the Component Model Cache (Visual Studio for C++).
in VS2013 it is located in
%localappdata%\Microsoft\VisualStudio\12.0\ComponentModelCache
in VS2015 in
%localappdata%\Microsoft\VisualStudio\14.0\ComponentModelCache
Rename this folder and restart visual studio.
I received this error because during the BizTalk install I did not check the Developer Tools and SDK checkbox. I went back and modified my installation and that error went away for me now.
Trying to load a BizTalk Project in VS2012 without BizTalk installed on your developer machine, will result in this error and the projects will load. This should be the first thing you check.
Make sure that all your extensions are same as in previous version. For me, when I upgraded from old PC to New PC, I didn't downloaded correct extensions hence resulting in above issue.
I faced out with this problem, the solution was:
Open VS2017
Go to Tools
Go to Extensions and updates
Search for Reporting Services Project and then "Enable"; close your VS.
Open again your project/solution.
