MSDN says that public static members of System.Windows.Application are thread safe. But when I try to run my app with multiple threads I get the following exception:
ArgumentException: An entry with the same key already exists.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.Collections.Generic.SortedList`2.Add(TKey key, TValue value)
at System.IO.Packaging.Package.AddIfNoPrefixCollisionDetected(ValidatedPartUri partUri,
PackagePart part)
at System.IO.Packaging.Package.GetPartHelper(Uri partUri)
at System.IO.Packaging.Package.GetPart(Uri partUri)
at System.Windows.Application.GetResourceOrContentPart(Uri uri)
at System.Windows.Application.LoadComponent(Uri resourceLocator, Boolean
bSkipJournaledProperties)
at System.Windows.Application.LoadComponent(Uri resourceLocator)
The application works fine on a single thread and even on two or three. When I get up past 5 then I get the error every time. Am I doing something wrong? What can I do to fix this?
