Remarks

This property allows you to target a specific version of a reference to an assembly for a project.

When used with a Reference item type, the Name property needs to be the full fusion name of the assembly to be resolved. The assembly is only resolved if fusion exactly matches the Name property.

When a project targets a .NET Framework version and references an assembly compiled for a higher .NET Framework version, the reference resolves only if it has SpecificVersion set to true.

When a project targets a profile and references an assembly that is not in the profile, the reference resolves only if it has SpecificVersion set to true.
