OfficeWriter and .NET 4.0: Resolving System.Web Dependency

Recently I had a customer who was trying to use OfficeWriter with .NET 4.0 and kept receiving the error:

Warning MSB3253: The referenced assembly “assembly name” could not be resolved because it has a dependency on “System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” which is not in the currently targeted framework “.NETFramework,Version=v4.0,Profile=Client”. Please remove references to assemblies not in the targeted framework or consider retargeting your project.

The application was being compiled to the .NET 4.0 Client Profile. An application that targets the .NET Framework 4 Client Profile installs the minimum set of client assemblies on the user’s computer, without requiring the full version of the .NET Framework 4 to be present+.+ This is a problem because the System.Web assembly is not included—but OfficeWriter has a dependency to System.Web (which is not available in the Client Profile).

The solution: you will need to build your console application against the full .NET 4.0 Framework, because of the dependency on System.Web

To do this, just right click on your project in the solution explorer, go to properties and set the target framework under the application tab to .NET Framework 4.

Just rebuild your application and you should be good to go.
