VS2010 LNK1181: cannot open input file 'Release\.NETFramework,Version'

I've been through th开发者_JAVA百科e similar questions and their answers don't seem to apply. Keep getting this error. Works ok with VS6.0 Checked all the settings and can't see NETFramework,Version or simialr anywhere in the project properties. Checked linker settings and can't see the input file NETFramework or Version anywhere.

cheers
