ASP.NET - How do I stop classes/dlls from one project being compiled into another project

Answer 1

ABC.DLL is referenced by your website and it becomes part of it (it is in Bin folder). ASP.NET compiles your website and ABC.DLL is placed in temp location (C:\Windows...\Temporary ASP.NET Filse...). It gets loaded by ASP.NET automatically. You are trying to load ABC.DLL manually from different location (D:\junk\abcabstract\bin\abc.dl). Two assemblies do not match hence you get the error.

To stop this from happening you have to rethink your plugin architecture I guess. Can you give more information?

Update: Why don't you fix it like this:

// Assembly _abc_assembly = Assembly.LoadFile(“c:\junk\abcabstract\bin\abc.dll”);
// ContentAttribute attribute;
// attribute = (ContentAttribute)_abc_assembly.CreateInstance("ABC.TextAttribute");
ContentAttribute attribute = new ContentAttribute();

Answer 2

It's a namespace collision. It doesnt know which ContentAttribute to use since it is finding 2 in different namespaces/assemblies.

You may have an old copy of the DLL named differently. Delete your temporary ASP.Net directories and recompile.

To avoid in the future:

Use fully qualified names for your objects if you need to get it to work.

ABC.ContentAttribute ca = new ABC.ContentAttribute();

or if casting do the same

ABC.ContentAttribute ca =(ABC.ContentAttribute)ca2;
