Steps to reproduce

1. Add msdeploy.exe as an executable
2. Add command task that use msdeploy and use -setParam:name="Foo Bar name",value=FooBarValue as argument in the command task
3. Run plan

Observation

The following error is thrown

Error: Unrecognized argument '"-setParam:name="Foo'. All arguments must begin with "-".

Workarounds

Either:
a) Use parameters without any space to avoid the use of quotes as it's not interpreted correctly.
b) Use a script task instead of the command task
c) Create a script file that encapsulates the targeted command and arguments.
