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.

Funny question but I stacked on it. I opened in VS2013 solution file which uses VS2012, but it still doesn't show me any screen for upgrade solution to VS2013. I mean I can open this project in VS 2013 and it works but solution file still shows that it use VS2012
According to this article some wizard should be shown, but it doesn't
http://msdn.microsoft.com/en-us/library/vstudio/ms185327(v=vs.100).aspx
Found the answer. We need to correct manually the Visual Studio sln file like this
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2013
VisualStudioVersion = 12.0.21005.1
MinimumVisualStudioVersion = 10.0.40219.1
Open the project using VS2013, then go the the directory that the project is in and change the
extension of the Solution file (*.sln) to something like *.sln_12. Now save the project and a new sln file will be created.
Check this url http://visualstudiomagazine.com/articles/2013/06/12/vs-2013-can-load-vs-2012-and-vs-2010-projects.aspx. It supports round-tripping with older versions of visual studio so it doesn't upgrade solution/project file automatically.
I have develop project in visual studio 2012 , but now im trying to open that project in visual studio 2010?its showing error like cant open the solution
In your .sln file, open with notepad and...
Change the:
Microsoft Visual Studio Solution File, Format Version 12.00
To:
Microsoft Visual Studio Solution File, Format Version 11.00
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.
I edited my project (which was written in school using Visual Studio 2008) at home using Visual Studio 2010 Express. When I got back to school, I couldn't open my solution anymore as Visual Studio 2008 told me that the file was created with a newer version of Visual Studio. I asked my professor for help and he edited something in the assembly information of the solution and voila, I could open, run, edit it again as nothing ever happened.
However, I forgot what he did with the assembly information. Does anyone here know what he could have done? or is this approach not advisable?
At the top of the .sln file there would be a line:
Microsoft Visual Studio Solution File, Format Version 11.00
If you change the version to 10.00, it would correspond to Visual Studio 2008. Use any text editor for this.
The file format has not changed in between these versions (nor has it for Visual Studio 2012).
Edit the .sln file in Notepad and find the version number (11.0) on the first or second line. Change it to 10.0, save the file, and you should be good to go.
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
