XmlSerializer for a type in dynamically loaded assemblyI have an assembly which I load using Assembly.Load(bytes[]). Within the Assembly i have a method which invokes XmlSerializer.serialize method on a type. This type is also within the assembly. However the serialize method throws an exception saying Unable to generate a serializer for type MyNamespace.Classtype from assembly <Unknown> because the assembly may be dynamic. Save the assembly and load it from disk to use it with XmlSerialization On a different machine the constructor for the serializer failed to generate with following error: Unable to generate a temporary class (result=1). error CS0234: The type or namespace name 'xxxxx' does not exist in the class or namespace yyyy Everything works fine if i load the assembly using LoadFrom. Is this a security problem? How do i solve it? Thanks in advance. The assembly needs to be on disk so the XMLserializer can reference it when
it generates the code to do your serialization.

you).. it will create a temp file anyways during compilation ... it is a question of whether or not it deletes it afterwords so you might as well just keep the file if you are using XMLSerialization on those objects :) Show quote "Greg Young" <druckdruckREMOVEgo***@hotmail.com> wrote in message news:eIz%23%23JztGHA.2392@TK2MSFTNGP05.phx.gbl... > The assembly needs to be on disk so the XMLserializer can reference it > when it generates the code to do your serialization. > > Cheers, > > Greg Young > MVP - C# > http://codebetter.com/blogs/gregyoung > > "kishore" <vkbul***@gmail.com> wrote in message > news:1154632511.401404.248460@75g2000cwc.googlegroups.com... >> Hi >> I have an assembly which I load using Assembly.Load(bytes[]).

reference to the assembly i loaded in to memory rather than on disk.
