I was under the assumption the solutions and / or C# projects created in VS 2012 could also be opened in VS 2010 (with SP1 applied).
But I wasn't able to do so - VS 2010 didn't want to load the solution file, and after I manually "tweaked" it, now it complains about the *.csproj project file being incompatible with this current version of VS 2010 .....
What am I missing?
You can fix it by,
1- Change 12.00 to 11.00
2- open *.csproj file by text editor and change this line
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
to
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
Project will open after restart of VS 2010
If you create a solution with visual studio 2012 on the top of your solution-file there are the following two lines:
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2012
You can Replace the Version 12 to 11. And than the solution should work in Visual Studio 2010. I'm not sure if the visual studio 2010 can handle project-files which have target .net-framework 4.5
Removing:
<AppContainerApplication>true</AppContainerApplication>
Under the tag:
<PropertyGroup Label="Globals">
Solved it for me. Though it is funny, on another PC (Win10 instead of 7) it worked including this line.

How to convert Visual Studio 2015 solution (.sln) to Visual Studio 2017.
In the past, when a solution from a previous version was opened in the newer VS there was a wizard doing the conversion, but it seems it's not the case in with these versions.
Edit the .sln file with a text editor like notepad. Change the first 3 lines to
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 15
The first line is empty.
When you save the changes, the icon of the .sln file is changed and the solution will be opened by VS 2017 when double-clicked.
I cannot find Retarget Solution.
What I did instead:
Open the solution file using Visual Studio 2017
Select the solution file in Solution Explorer.
Type Ctrl-S
Actually I got the idea from here:
Upgrade Visual Studio 2013 solutions to Visual Studio 2015
open solution(sln) with vs2017
if prompt 'Retarget Project ...' click ok and done!
else in Solution Explorer > right click on solution name
select 'Retarget Solution'
5. select last version sdk and click ok and done!
In my case, I've searched and applied all solutions.
Installed netcore 2.1 x86 x64
Reinstalled VS2017
What was the solution?
There was a global.json next to the solution and it contained an sdk parameter, I changed it to 2.1.413 (the latest as of today 25/10), and it now compiles!!!
I am trying to build fltk 1.1.10 in Visual Studio 2013 but I get the warning
"fltk.sln: Visual Studio needs to make non-functional changes to this project in order to enable the project to open in Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1 without impacting project behavior."
After searching, I found out how to do this for a C# project but how can I do it for fltk.sln?
Many thanks for the help.
There are 3 solutions in the FLTK1.1.10 distribution
visualc - for Visual Studio 6
vcnet - for Visual Studio 2003
vc2005 - for Visual Studio 2005
None of these will load directly into VS2013. They have to be converted to VS2013 format. Easiest way is to make a copy of vc2005 and call it vc2013. Then start fltk.sln. It will tell you that it needs to make a one way upgrade with the message you described. Just click OK.
What this does is migrate the 2005 sln to 2013 sln and migrate the vcproj files to vcxproj files. Basically you don't lose the vcproj files - you just get completely new versions of vcxproj files. Once that is done, just do a build.
I have a project in Microsoft Visual Studios 2013 and I want to open it in Microsoft Visual Studios 2010. Is there any easy way? or Do I have to create a new project in 2010 and add all files from 2013 project?
Open you solution file in notepad. Make 1 change, as stated in Converting VS2012 Solution to VS2010:
Replace "# Visual Studio 2013" with "# Visual Studio 2010" (without
quotes.)

How to downgrade from Visual Studio 2012 project to Visual Studio 2008
I had some issues that were resolved by a combination of things. In my case I was converting a VB 2013 project to 2010. I solved it by:
Open the solution file in notepad (.sln)
Change these lines:
Microsoft Visual Studio Solution File, Format Version 12.00
Visual Studio 2013
To:
Microsoft Visual Studio Solution File, Format Version 10.00
Visual Studio 2010
I also had to update the references. I had the issue that it give an error every time I went to view designer. In my case it was:
Microsoft Excel 15.0 Object Library -> Microsoft Excel 14.0 Object Library
Microsoft Office 15.0 Object Library -> Microsoft Office 14.0 Object Library
Reassign the Microsoft Visual Basic for Applications Extensibility 5.3
open the solution file with notepad and editing like
Format Version 12.00===> Format Version 11.00
Visual Studio 2013===> # Visual Studio 2010
is also working
I changed ToolsVersion="12.0" to ToolsVersion="4.0" in my .csproj file and .csproj.user file, I hope it helps someone out there.
(credit to #PandiyanT and #talmok)
This worked for me: open the solution(.sln) file with Notepad and change right values to left values in this way :
Format Version 12.00 to Format Version 11.00
Visual Studio 2013 to # Visual Studio 2010
and then open visual C# project file with notepad and change right value to left value in this way :
ToolsVersion="12.0" to ToolsVersion="4.0"
For 2015 to 2010 Premium use these lines in the .sln file.
Microsoft Visual Studio Solution File, Format Version 11.0
# Visual Studio 11
VisualStudioVersion = 10.0.40219.1
MinimumVisualStudioVersion = 10.0.40219.1
Had to change to these 2 lines. Changed from 12 to 11. And changed from 4.5 on the framework to 4.0 on the project file .csproj
<Project ToolsVersion="11.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
How would you open a Visual Studio 2010 .sln file in Visual Studio 2008?
Is it possible? Are there any workarounds?
Have a look at these questions for information about how to convert the solution file between VS2008 and VS2010:
VS2010 possible to convert projects back to VS2008?
VS2010 and VS2008 project compatibility
But keep in mind, that once you have used some of the .NET 4 features (while in VS 2010), you will not be able to continue working with that solution in VS2008, since it does not support .NET 4. On the other hand, when using VS2010, you can still target .NET 3.5 or 2.0.
I think I need more information... but I will try it.
One option is to create a new project in VS 2008 and simply add the files to the project.
Other option is to edit the .sln file and replace* Microsoft Visual Studio Solution File, Format Version 11.00.* with Microsoft Visual Studio Solution File, Format Version 10.00.
The open the .csproj file and replace
with
Open the solution file (.sln) with notepad and change
Microsoft Visual Studio Solution File, Format Version 11.00
Visual Studio 2010
to
Microsoft Visual Studio Solution File, Format Version 10.00
Visual Studio 2008
Then open the solution file from visual studio 2008
I have created a project using Visual Studio 2008 and .NET Framework 2.0.
Now I want to open it in Visual Studio 2005 (.NET Framework 2.0).
When I try to open the solution in Visual Studio 2005 it is showing an error as "It is created using the Higher versions".
So is there any way I could open the project in Visual Studio 2005?
Or should I redo the entire project in Visual Studio 2005?
Please help me out!
Thanks in advance!
You can edit the solution file and project files (not recommended, but you can). If it's a csproj file, change the line
<ProductVersion>9.0.30729</ProductVersion>
to
<ProductVersion>8.0.50727</ProductVersion>
If it's the sln file, change:
Microsoft Visual Studio Solution File, Format Version 10.00
to
Microsoft Visual Studio Solution File, Format Version 9.00
Try opening the project file instead of the solution file. Otherwise just create a new VS2005 project and add all the files and folders from the VS2008 project.
You can use Visual Studio Project Converter, a handy tool to convert between most versions of Visual Studio (VS 2002, 2003, 2005 and 2008).
But unfortunately, converting .NET projects is not supported.
I have just encountered the same problem.
Modifying the .sln file and .csproj file by notepad is the solution.
If want to know more about the file format, we can create a simple project both in VS2005 and VS2008, then compare the project files.
