Create Guid in Visual Studio 2008
It is possible someone else already blogged about it but a lot of SharePoint developers seem to have problems to generate GUIDs when using Visual Studio 2008. We are used to click the Tools menu and choose Create Guid but unfortunately this option is disabled when you start using Visual Studio 2008.
This is because the guidgen.exe tool is located somewhere else now: it comes with the Windows SDK now.
I’ve seen a lot of inventive ways to create Guids the last couple of months but copy/paste an existing one and changing a part of it is definitely not the way to go.
You can enable the Create Guid option again in Visual Studio 2008.
1. Choose the Tools -> External Tools...
2. Click the Browse (…) button and find the guidgen.exe in the C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\ folder.
3. Click the OK button.
There you go. Creating GUIDs is now as easy as it was in Visual Studio 2005. You have no excuse anymore to manually edit a copied Guid.
