Microsplat missing assembly reference

I installed microsplat and map magic 2. When I install microsplat integration, I get this error:

Assets\Plugins\MapMagic\Compatibility\Runtime\MicroSplatOutput.cs(81,11): error CS0246: The type or namespace name 'MicroSplatPropData' could not be found (are you missing a using directive or an assembly reference?)

How can I fix this?
