Is there a way to open a solution-file saved in Visual studio 2010 beta 2 in Visual studio 2008? ... or maybe a way to convert it?
When i tried to open it in VS 2008 i get an error saying "The selected file is a solution file, but was created by a newer version of this application and cannot be opened."
If you open up the .csproj file in a text editor (it's just XML) you'll see a line like:
<ProductVersion>9.0.30729</ProductVersion>
(this is from a VS 2008 project)
The first line of a 2008 .sln file reads as follows:
Microsoft Visual Studio Solution File, Format Version 10.00
The 2010 version numbers will be different - just change them to these values (or the ones you get from creating a new 2008 project on your system).
Just take a backup of the files first.
