VS.NET 2010 fails to compile program created earlier in VS.NET 2008

Trying to recompile a program in Visual Studio 2010, which was originally created using Visual Studio 2008 (which is still on my PC), I got this baffling message:

Error 9 Task failed because "sgen.exe" was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for "sgen.exe" in the "bin" subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v6.0A. You may be able to solve the problem by doing one of the following: 1) Install the Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5. 2) Install Visual Studio 2008. 3) Manually set the above registry key to the correct location. 4) Pass the correct location into the "ToolPath" parameter of the task.

These suggestions were too bizarre even to consider, and so I Googled. Right away, I found this nice blog entry which helped me out, and just in case it were to go away, I'm duplicating the helpful information it contains below. So, courtesy of the "dukelupus" blog, everything after this paragraph is copied verbatim from that blog.

Changing the registry key will not help nor will adding C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\ to the path. I did not try other solutions...I used FileMon to check what Visual Studio is looking for – and it appears that it will always look for that file at C:\WINDOWS\Microsoft.NET\Framework\v3.5\, which does not contain sgen.exe.

Just copy sgen.exe from C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\ to C:\WINDOWS\Microsoft.NET\Framework\v3.5\ and everything will now compile just fine. Here, to make your life easier, copy command:

copy /y “C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\sgen.exe” “C:\WINDOWS\Microsoft.NET\Framework\v3.5\”

Good luck!
