Invalid .resx file after renamed namespace

Question

Consider the following situation:

• In my Windows Forms appliation I have a form.
• That form has a .resx file.
• The form makes use of a class ("OtherClass") from another assembly ("Other.dll").
• "Other.dll" is built in the same VisualStudio 2010 solution as the main application (just a separate project in the same solution).
• In the main project (the Windows Forms application) I have properly added a reference to the "Other.dll" project.

Everything works well (as expected).

Now I need to change the namespace of the type contained in "Other.dll" from "Old.Namespace" to "New.Namespace":

1. In VS2010, I bring up the Properties window of the "Other.dll" project
2. I change the namespace in the "Default namespace" text box from "Old.Namespace" to "New.Namespace"
3. I change namespaces in related .cs files accordingly
4. I rebuild the modified "Other.dll" project. No errors. The modified "Other.dll" is produced OK.

Now comes the problem:

When I after this rebuild the whole solution, the compiler stops and reports that the .resx file of the form is invalid:

---

"Invalid Resx file. Could not load type Old.Namespace.OtherType, Other, Version 1.0.0.0, Culture=neutral, PublicKeyToken=null which is used in the .RESX file. Ensure that the necessary references have been added to your project. Line 1521, position 5"

---

Clearly, the .resx file still references the type with the old namespace from somewhere. That "somewhere" appers to be from inside the binary section of the .resx file!

Question: How can I make the .resx understand that it must now reference the new type (with the changed namespace)?

Please help, I really don't know how to proceed here...

Answer 1

I've had the same problem and the solution was to remove the data sections from the resx file

Answer 2

I too had the same problem, and after trying several other options I followed Stefania Mereut's advice and deleted the data sections from the resx file. When I re-added the resources, it apparently rewrote the data sections correctly.
