ADO.NET Dataservice hosting på IIS
Hej alle eksperter!Jeg har lige lavet en dataservice som jeg prøver at hoste på en ekstern IIS. Så får jeg følgende fejl.
Exception has been thrown by the target of an invocation.

Når jeg kører det fra Visual Studio virker det fint. Nogen der har en idé om hvad problemet er?
Så det er når jeg publisher det til en IIS fejlen kommer.
Håber i kan hjælpe!
