Deserialization exception : Unable to find assembly

Question

I work on winforms project.

I try to deserialize an object:

private void CreateObjects()
        {
            try
            {
                using (FileStream fs = new FileStream("path to file", FileMode.Open))              
                   sObjects = (Objects)(new BinaryFormatter().Deserialize(fs)); 
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
        }

But in this row:

sObjects = (Objects)(new BinaryFormatter().Deserialize(fs)); 

I get this exception:

Unable to find assembly 'TheNameOfTheClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Any idea what may cause this exception?

If your class con taint object that do not have the Serializeable tag, you can't Deserialize them. You will need to mark these object with the NonSerializable tag.

If in your AssemblyInfo.cs version defined like this:

[assembly: AssemblyVersion("1.0.*.*")]
[assembly: AssemblyFileVersion("1.0.*.*")]

Then change it to this:

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
