Unresolved assembly reference: PresentationCore? (.NET 4.0)

May 7, 2010 at 10:24 PM


Currenty i am deploying an .NET Project and i want to generate the help file using shfb.

But i get following a build error:

[Sandcastle Help File Builder Utilities, version]

SHFB: Error BE0043: Unexpected error detected in last build step.  See output above for details.


My first try was to add a reference to the unresolved assembly (C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\Profile\Client\PresentationCore.dll) but it doesn't fixed the build error.

In the project properties from shfb i declared the FrameworkVersion as 4.0.30319

What am I doing wrong?

The May 2008 release of Sandcastle doesn't support .NET 4.0 without the latest Sandcastle Styles patch.  The patch is current as of the VS 2010 RC release so you will need to update the supplied MRefBuilder.exe.config to include the .NET 4.0 RTM version number.

Thank you very much for your reply. Now it wokrs, so for any other user who wants this error fixed, yiu have to:

1. Install the latest Sandcastle Styles patch (for me it was Sandcastle May 2008 (2.4.10520) Patch - Rev 3)

2. Fix your MrefBuilder.exe.config file: see here
