Build your solution with Visual Studio from MSBuild
Unfortunately MSBuild and BIDS Helper are not able to build an .asdatabase from our Analysis Services project (.dwproj). Here is a task which invokes Visual Studio to build such a solution:
<Target Name="DevEnvBuild">
<Error Condition="'$(SolutionFile)'=="" Text="Missing SolutionFile" />
<PropertyGroup>
<DevEnvTool Condition="'$(DevEnvTool)'=="">C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe</DevEnvTool>
<DevEnvSwitch Condition="'$(DevEnvSwitch)'=="">Build</DevEnvSwitch>
<DevEnvBuildCommand>"$(DevEnvTool)" "$(SolutionFile)" /$(DevEnvSwitch)</DevEnvBuildCommand>
</PropertyGroup>
<Exec Command="$(DevEnvBuildCommand)" />
</Target>
