What could cause the Wmi custom MSBuild task to throw "ManagementException not found"?

Question

The Wmi task is part of the MSBuild Extension Pack. On one of our development machines, it thrown ManagementException not found. Here's the target:

<Target Name="Clean">
    <ItemGroup>
      <WmiProps Include="State"/>
      <WmiProps Include="DisplayName"/>
    </ItemGroup>

    <!-- Create list of VIKAD services that are currently running. -->
    <Wmi TaskAction="Query" Class="Win32_Service WHERE DisplayName LIKE '%ServiceName%'" Properties="@(WmiProps)" Namespace="\root\CIMV2" MachineName="$(LocalDbServer)">
      <Output TaskParameter="Info" ItemName="Info"/>
    </Wmi>

    <Wmi TaskAction="Execute" Class="Win32_Service" Method="StopService" Instance="Name='%(Info.DisplayName)'" Namespace="\root\CIMV2">
      <Output TaskParameter="ReturnValue" PropertyName="Rval1"/>
    </Wmi>
</Target>

The second WMI task is the one that throws the exception.

Answer 1

The error is pretty straightforward (the class wasn't found). I believe it's happening because you're attempting to query for a service by it's display name, not it's actual name. Switching the second task to be

Instance="Name='%(Info.Name)'"

Should probably do the trick.

Hope this helps,
