|
<PRE>I too am having a very similar issue.
|
|
The only real difference is that we use actual Dictionaries instead of
|
|
IDictionary.
|
|
I believe the issue stems from having a custom or complex type as either the
|
|
key or value in your dictionary.
|
|
I have tested it sending a string for the key and an int for the value and
|
|
it works fine.
|
|
|
|
I have also used fiddler to examine the difference in the SOAP between the
|
|
XML that mono sends and the xml that .NET or Silverlight sends. What I have
|
|
found is that .NET and Silverlight appends what appears to be a seemingly
|
|
random set of characters onto the end of the type name. But in truth it must
|
|
not be random because through different projects and compiles the string
|
|
remains consistent. I have also noticed that it changes depending on what
|
|
namespace your custom class is in. So it must be some form of digest of a
|
|
namespace. Without this, the WCF server is unable to deserialize the
|
|
dictionary properly.
|
|
|
|
Below is an example of the dictionary in XML created by mono and then the
|
|
XML created by .NET.
|
|
This is in a namespace called Joe and is a dictionary keyed by string with a
|
|
value of type SimpleTest.
|
|
|
|
Mono:
|
|
<d4p1:NewDict
|
|
xmlns:d5p1="<A HREF="http://schemas.microsoft.com/2003/10/Serialization/Arrays"">http://schemas.microsoft.com/2003/10/Serialization/Arrays"</A>>
|
|
<d5p1:KeyValueOfstringSimpleTest>
|
|
<d5p1:Key>TestKey1</d5p1:Key>
|
|
<d5p1:Value>
|
|
<int1
|
|
xmlns="<A HREF="http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"">http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"</A>>1</int1>
|
|
<string1
|
|
xmlns="<A HREF="http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"">http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"</A>>Test1</string1
|
|
</d5p1:Value>
|
|
</d5p1:KeyValueOfstringSimpleTest>
|
|
</d4p1:NewDict>
|
|
|
|
.NET
|
|
<d4p1:NewDict
|
|
xmlns:d5p1="<A HREF="http://schemas.microsoft.com/2003/10/Serialization/Arrays"">http://schemas.microsoft.com/2003/10/Serialization/Arrays"</A>>
|
|
<d5p1:KeyValueOfstringSimpleTest3HyOSdeZ>
|
|
<d5p1:Key>TestKey1</d5p1:Key>
|
|
<d5p1:Value
|
|
xmlns:d7p1="<A HREF="http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"">http://schemas.datacontract.org/2004/07/Origin.BLL.Joe"</A>>
|
|
<d7p1:int1>1</d7p1:int1>
|
|
<d7p1:string1>Test1</d7p1:string1>
|
|
</d5p1:Value>
|
|
</d5p1:KeyValueOfstringSimpleTest3HyOSdeZ>
|
|
</d4p1:NewDict>
|
|
|
|
Notice how .NET appends "3HyOSdeZ" on the end of SimpleTest.
|
|
|
|
Where you able to come up with a solution to your issue?
