MORE INFORMATION

If the problem still exists after you install the hotfix, follow these steps:
  1. In the Program Files\MSBuild\v3.5 folder, create a file named "Custom.After.Microsoft.Common.targets" that has the following content:
    <Project xmlns="http://schemas.microsoft.com/developer/MSBuild/2003">
        <PropertyGroup>
        </PropertyGroup>
        <Target Name="AfterClean">
                <CallTarget Targets="GetTargetPath" UseResultsCache="true" Condition="'$(UnloadProjectsOnCompletion)'=='true'"/>
        </Target>
        <Target Name="AfterBuild">
                <CallTarget Targets="GetTargetPath" UseResultsCache="true" Condition="'$(UnloadProjectsOnCompletion)'=='true'"/>
        </Target>
         <Target Name="AfterPublish">
                <CallTarget Targets="GetTargetPath" UseResultsCache="true" Condition="'$(UnloadProjectsOnCompletion)'=='true'"/>
        </Target>
    </Project>
    
  2. At the command prompt, go to the folder in which the Tfsbuild.proj file is located, and then run the following command:
    MSBuild.exe /tv:3.5 /p:UnloadProjectsOnCompletion=true /m /t:desktoprebuild tfsbuild.proj
    Note If you are not using Team Build to start Msbuild.exe, replace "tfsbuild.proj" with the name of your project file and replace "/t:desktoprebuild" with the target that you want to build.
