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.)

Please take a look at reference link..and also this https://vsprojectconverter.codeplex.com/ – Vignesh Kumar A Dec 10 '13 at 05:36
Are we assuming that the 2013 project was using .Net 4.0? Do we need to check that as well? – toddmo Feb 25 '15 at 18:51

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

I changed ToolsVersion="12.0" to ToolsVersion="4.0" in my .csproj file and .csproj.user file, I hope it helps someone out there.

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"

# 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>
