We need to build our system for both .NET 3.5 and .NET 4.5.1 Our system is a reporting engine composed of a bunch of DLLs. Many of our customers are still on the .NET 2.0 runtime, hence we must have a .NET 2.0 version.
However, we also need to have 2 optional DLLs that require .NET 4.0, one for the OData API and one for the new Oracle connector. Both of these require the .NET 4.0 runtime.
Is there a way to use the existing solution & project files and from the command line tell it to build for 3.5 or 4.5.1? Or do we need to duplicate all the solution & project files?
thanks - dave
