Could not find file 'Syncfusion.Diagram.Base.resources


I have migrated my application from visual studio framework 3.5 to 4.0 so due to migration i have added syncfusion 4.0 dll to my application,
At runtime during intialization of diagram control application is throwing  "Could not find file 'Syncfusion.Diagram.Base.resources", 
So please give some solution to resolve the issue.


   private void InitializeComponent()
            this.components = new System.ComponentModel.Container();
            System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(LayoutConfiguratorUserControl));
            this.diagramLayoutConfigurator = new Syncfusion.Windows.Forms.Diagram.Controls.Diagram(this.components);

I've got the same problem.
After upgrading from a very old Syncfusion version from 2008 to Syncfusion 14 I get the same error as Rashmi Mohan.

What I've tried so far:
 - Reinstalling Syncfusion
 - Removing assemblies from the GAC and installing them again afterwards
 - Using the project migration tool
 - Removing the diagram control from the form in our application and placing it again on the form

I can start your demo application without problems, but in our applications it's always crashing at runtime.
But I can view and edit the diagram control just fine at desing time.

I found the solution!

We've implemented Syncfusion Symbol Designer-Files in our project (*.edp-files).
Theses files are added as resource in visual studio and are getting deserialized at runtime with a BinaryFormatter, like this:

 IFormatter formatter = new BinaryFormatter();
 AppDomain.CurrentDomain.AssemblyResolve += DiagramBaseAssembly.AssemblyResolver;

this._resourcePalette = formatter.Deserialize(new MemoryStream(serializedNodeTemplates)) as SymbolPalette;

The orange line is the reason for the exception, because when I uncomment this line, the diagram can be created but the
_resourcePalette is empty (so it's crashing at a different part in my application).

I'll googled for DiagramBaseAssembly.AssemblyResolver and found this: https://www.syncfusion.com/forums/79037/symbol-designer-and-diagram-editor
From this post, I copied this line:
formatter.Binder = Syncfusion.Runtime.Serialization.AppStateSerializer.CustomBinder;

Now my code looks like this:

 IFormatter formatter = new BinaryFormatter();
 formatter.Binder = Syncfusion.Runtime.Serialization.AppStateSerializer.CustomBinder;

 this._resourcePalette = formatter.Deserialize(new MemoryStream(serializedNodeTemplates)) as SymbolPalette;

_resourcePalette is not null this time and everything works fine! :)

Ah, I forgot something!

I've opened and saved all the edp-files once with the newer version of the Symbol Editor from Syncfusion, before I changed my code.

But I don't know if this is needed. That was just my first asumption, that the edp-files are outdated.
