Could Not Load Type Microsoft.Build.Framework.BuildEventContext

Setting up a TeamCity build and got this error:

C:Program FilesMSBuildMicrosoftVisualStudiov9.0TeamDataMicrosoft.Data.Schema.SqlTasks.targets(80, 5): error MSB4018: The "SqlSetupDeployTask" task failed unexpectedly.
System.TypeLoadException: Could not load type ‘Microsoft.Build.Framework.BuildEventContext’ from assembly ‘Microsoft.Build.Framework, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

The usual searching didn’t bring back anything useful, but I figured out that I’d 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…).
