Setting up a TeamCity build and got this error:

C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.Data.Schema.SqlTasks.targets(80, 5): error MSB4018: The "SqlSetupDeployTask" task failed unexpectedly.

The usual searching didnt bring back anything useful, but I figured out that Id missed a dropdownlist in the TeamCity project setup:

Originally I was using Microsoft .NET Framework 2.0 for my MSBuild task.  Changing it to 3.5 (as shown above) got me past this error (and on to the next one).

Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
