Error round-tripping assembly

[JohnC-6]

I have uploaded a file rapptor.zip which contains a
rapptor.persistence.dll assembly. Cecil cannot round trip the assembly
correctly.

Here is code to reproduce the error:

            try
            {

                AssemblyDefinition ad = AssemblyFactory.GetAssembly
(@"c:\RAPPTOR.Persistence.dll");
                AssemblyFactory.SaveAssembly(ad, @"c:\output
\RAPPTOR.Persistence.dll");

                Assembly a = Assembly.LoadFile(@"c:\output
\RAPPTOR.Persistence.dll");
                a.GetTypes();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
                ReflectionTypeLoadException rtle = ex as
ReflectionTypeLoadException;

                if (rtle != null)
                {
                    foreach (Exception ee in rtle.LoaderExceptions)
                    {
                        MessageBox.Show(ee.ToString());
                    }
                }
            }

Dear Jb,

Upon further research, I found that if I disassemble the assembly
using ildasm and remove the generic parameter constraints and then re-
assembly and round-tripping, the error does not occur.

FYI, there are 5 instances where generic parameters are constrained -
they are all in the 'RAPPTOR.Persistence.DataModel.REF' namespace  and
all the constraints are "where T : ManagedObject".

Hope this will information will help in trouble-shooting the issue.

Let me know if there is anything I can do or if you need more info.
