Error Message: "Fehler beim Laden der Eigenschaftenliste anhand des Namespaces, oder Eigenschaften in der Liste nicht gefunden."

On a German installation, the BizTalk server threw the following error message after parsing a message:

Fehler beim Laden der Eigenschaftenliste anhand des Namespaces, oder Eigenschaften in der Liste nicht gefunden, Überprüfen Sie, ob das Schema korrekt bereitgestellt wurde.

Actually, this error states already the problem quite good, which is that the message contains a promoted property that doesn't exist in the schema property. So, if you get this error message, go through your code and have a close look at all properties that you set and check whether you've spelled their names correctly.

Weired Error "This is often an indication that other memory is corrupt." executing pipeline component

After migrating our biztalk app to 2009 we received a confusing error message everytime we dropped a file into a file receive location with a pipeline containing a bunch of pipeline components:

"There was a failure executing the receive pipeline:
...
Reason: Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

After along irritating searching we finally debugged the pipeline component and find the root cause:
The call of

message.Context.Read(propertyName, propertyNamespace);

within an pipeline component must not be done with a "Null" value of "propertyNamespace". Obviously there is no internal check for this and the following call within the unsafe code leads into a Null reference call and the error message above.

If the Pipeline Component doesn't appear in the Pipeline Editor toolbox

If your BizTalk pipeline component doesn't show up in the toolbox of the pipeline editor, you should check these things:

• Is the GUID of the pipeline component the same in AssemblyInfo and in the class itself (it appears twice there)?
  
  
• Is the right assembly name used when instanciating an object of ResourceManager?
  
  
• Are you using the same namespace outside the class, in the properties, and in the ResourceManager?
  
  
• Is the assembly copied to %biztalk installation%\pipeline components?
  
  
• Are you looking for the right component type (encoder, decoder, ...) in the pipeline editor?
