Serializable class problem

[kevininstructor]

I created two classes called "site" and "Sites" which use 'BinaryFormatter'
to load and save class information to a disk file. In my test application
all works fine but when implementing into another application the code fails
with a message indicating there is a missing assembly. The missing assembly
is the project which serialized the class information to disk e.g.

Test1a, created binary files
DDEP attempted to read them but error points to "Test1a"


My solution was to recreate the data file in the DDEP project which then
marks the data for DDEP and "Test1a" gets the exception "can not find
assembly..."


MY QUESTION:
With the supplied code in mind is there a work around which would allow the
binary disk file to be accessed by any .NET application, or do I need a
different solution to mine? Please note I would like to stay binary to keep
the average user out of the files content.

Thanks for taking the time to read this message and provide feedback,
