Can the installutil be used to install a service written with a newer version of the .NET Framework?
For example can the version from .NET Framework 2.0 be used to install a service written in .NET 4?
I'm aware that technically the version from .NET 4 should technically be available on account of the fact the service will obviously require it.
Additional information The reason for asking this is that a tool which we use to install services appears to be hard-coded with a path to the .NET Version 2.0 framework installutil. However the service I wanted to install was built with the .NET 4.0 Framework
回答1:
A application written to use any particular version of .NET needs that version of .NET installed. As long as the required version of .NET is installed, the service exe can execute. If the service exe can execute, the INSTALLUTIL can install it (assuming all other dependent assemblies are accessible).
回答2:
It turned out that you do actually need a version at least as new as the version of the framework the assembly is written in.
