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:
<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.
