Running PDFNet SDK with Studio 2010 w/ .NET Framework 4.0 BETA ( or RC )

Q: Today I downloaded your trial for pdfnet SDK (4.8). We are
developing an application using the new Visual Studio 2010 w/ .Net
framework 4.0 BETA. I was wondering if you have a beta version or
anything that will work with Visual Studio 2010 w/ .Net framework 4.0.
A: This is due to incompatibility MS introduced with VS2010. You
should be able to use PDFNet with .NET Framework 3.5 without any

To fix .Net v4 issue add 'useLegacyV2RuntimeActivationPolicy' flag to
your 'app.config'. For example:

<?xml version="1.0"?>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

Once Visual Studio 2010 is officially released we will make sure that
all samples are properly tagged and we may offer a special version
compatible with the new RuntimeActivationPolicy.

Alternatively we recommend switching .NET Framework of 3.5 (since our
clients run into other issues related to 4.0 of .NET Framework) until
the official version of VS2010 is released.

FYI, To go around .NET 4 incomatibilities and new security model we
have released a new version of PDFNet that specifically targets .NET 4
and higher (VS2010). You can download the new version using the
following link:

Do you have a 64-bit version of the VS2010-dll?

We have recently released a version of PDFNet for .NET 4 (32-bit and
64-bit: We are planning
to thoroughly integrate this version with WPF as part of upcoming

At the same time we are planning to contine with full support for all
previous versions of .NET Framework starting with 1.1x.
