Hi,
I've been using 5.3.0 on my x64 Vista system without problems. After upgrading to 5.3.1 my WCF projects are broken. VS2008 is running WcfSvcHost which no longer finds the meta data:
"WCF Service Host cannot find any service metadata. This may cause the client application to run improperly..."
This doesn't happen on x32. It makes no difference running with full elevated rights. After downgrade to 5.3.0 everything is working again.
Regards
Martin
