It'll require some debugging 1. Open NopSolutions.NopCommerce.BusinessLogic.Products.ProductVariant class 2. Set breakpoint into get accessor of LocalizedName property 3. See why NullReferenceException is thrown
And if I have to work on it from my local computer and then recompile everything... I set the breakpoint at the place mentioned and when I run it I get the error: Error 1 Could not load type 'System.Data.Entity.Design.AspNet.EntityDesignerBuildProvider'. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config 129
That's the line in web.config: <add extension=".edmx" type="System.Data.Entity.Design.AspNet.EntityDesignerBuildProvider" />
