There doesn’t seem to be a way to create GUIDs out-of-the-box in MSBuild or through the MSBuild community tasks, so I created a custom task to do it for you.

Usage:

<!–

This task creates a new GUID using System.Guid.NewGuid()

The Format parameter is optional. If specified it must be one of “N” “D” “B” “P” “”. Default is “D”

See http://msdn2.microsoft.com/en-us/library/s6tk2z69.aspx for more information.

N = 32 digits: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
D = 32 digits separated by hyphens: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
B = 32 digits separated by hyphens, enclosed in brackets: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
P = 32 digits separated by hyphens, enclosed in parentheses: (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

–>

<CreateGuid Format=”D”>
    <Output TaskParameter=”Output” PropertyName=”MyGuid” />
</CreateGuid>

<Message Text=”Guid: $(MyGuid)” />
