How to detect .Net 2.0 SP1 in my installer?

How can I detect if .Net 2.0 SP1 is installed from my installer msi, and abort the install if it开发者_开发知识库 is not present?

I know how to do this in code, but it seems cleaner do it in the vdproj. It feels more declarative.

All you need is a Launch Condition Editor where you can set minimum .net version installed on the client machine to 2.2.30729 (.net 2.0 sp1). Hopes it helps.

You could check the value of the MsiNetAssemblySupport property, comparing it to the version number for Fusion.dll when .Net 2.0 SP1 is installed.
