July 29, 2010 Leave a Comment
If you want to convert a C# project in Visual Studio 2008 to one in Visual Studio 2010 without going through the conversion process by opening it in Visual Studio 2010, then you simply need to open and edit two files in notepad.
First open the solution file and change the following two lines
Microsoft Visual Studio Solution File, Format Version 10.00
# Visual C# Express 2008
to
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio 2010
and then open each project file and change the entry near the top of the file from
ToolsVersion="3.5" to ToolsVersion="4.0"
