The forum will be down for scheduled maintenance on Saturday, March 4 beginning at 10am EST. Actual downtime is unknown but may be several hours.

We updated to one of the latest EBFs for 12.0.1 and since we have the problem, that VS2010 is not able to build one of our projects:

error XC1000: XC1020: Build error occurred in the XAML MSBuild task: 'Could not load
type 'System.Runtime.CompilerServices.ExtensionAttribute'

If we use any iAnywhere.Data.SQLAnywhere.v4.0.dll prior to 3817 no problem.

After some search on the web we found, that this might be a side effect of an (not very obvious) incorrect usage of ilmerge. See the answer to the Stackoverflow question regarding 'System.Runtime.CompilerServices.ExtensionAttribute'

For us this is a critical issue, as we definitely would like to update the iAnywhere.Data.SQLAnywhere.v4.0.dll

Any help is appreciated...

This is likely a problem that is fixed by CR #733902 - there was a problem with the build configuration for our .NET 4 and .NET 4.5 drivers where some references were inter-mixed. I believe that is the source of the build error above.

You can find the download of the 12.0.1.3895 x86/x64 Windows EBF here.
