How to convert a VS 2010 solution back to 2008

Question

We started using VS 2010 and were very happy with it, so we converted our project into a 2010 solution (still .net 3.5) and continued our development in 2010. However, we are getting a lot of bugs recently and want to go back to 2008. The solution files have changed (new projects and files added everywhere), but everything is still in .net 3.5. I was wondering if there is an easy way to migrate back to 2008.

Answer 1

You can use "Project Converter": http://www.emmet-gray.com/Articles/ProjectConverter.htm

I have just found it. I am going to test it right now! :-)

Answer 2

Please try the following (find first line and replace to second line to convert 2010 solution to 2008):

TargetFrameworkMoniker = ".NETFramework,Version=v2.0"
TargetFramework = "3.5"

# Visual Studio 10
# Visual Studio 2008

Microsoft Visual Studio Solution File, Format Version 11.00
Microsoft Visual Studio Solution File, Format Version 10.00

<Project ToolsVersion="4.0"
<Project ToolsVersion="3.5"

<ProductVersion>10.0.20506</ProductVersion>
<ProductVersion>9.0.30729</ProductVersion>

\VisualStudio\v10.0\
\VisualStudio\v9.0\

<Import Project="$(MSBuildToolsPath)\Workflow.Targets" />
<Import Project="$(MSBuildExtensionsPath)\Microsoft\Windows Workflow Foundation\v3.5\Workflow.Targets" />

This worked on my solutions, you can try to see if it fit to your cases.
