.Net (Cannot Load Assembly)

[VB_Autocad_guy]

Hello,

I get this strange error in my Command Window. 

Any ideas what's going on? 

My .Net app appears isn't recognizing commands either. 

Cannot load assembly.

        Try
            'add anything that needs to be instantiated on startup

            ed.WriteMessage("<<[Initializing - VB.NET:ClassAutocad2011.dll Loaded]>>")

        'handle closing down a link to a database/etc.

        Console.WriteLine("Cleaning up...")
    End Sub

I'd start looking here:

To quote Tony:

You have multiple CommandMethod attributes, or
LispFunction attributes with the same command
or function name

I think I had 2 functions with the same name, I'd look for that first.

[VB_Autocad_guy]

Yep that was it!

Sloppy code... had duplicate Command Methods. 

I had two <CommandMethod("listrib")> _ in two different places. 

That would make sense why it would hang up autocad and stop recognizing commands as they are global. 

Many Thanks for helping me see my blind spot!

I would like to add an additional bit of help in case anyone else needs to know.

You get the same error if you accidentally forget to change the 'Copy Local' property to false when adding a Acad reference to your project ...

Bugged me for a couple of hour because I only had *one* CommandMethod therefore couldn'y understand why the solution was to remove a duplicate!

Hi,

You can define as many CommandMethod attributed methods as you want in the same class.

Posting here because $searchEngine brought me here for my error ...

Cannot load assembly. Error details: Autodesk.AutoCAD.Runtime.Exception: eInvalidInput
   at Autodesk.AutoCAD.Runtime.CommandClass.AddCommand(ICommandLineCallable ca, MethodInfo mi)
   at Autodesk.AutoCAD.ApplicationServices.AutoCADApplicationHolder.Initialize(Assembly assembly)
   at Autodesk.AutoCAD.ApplicationServices.ExtensionLoader.ProcessAssembly(Assembly assembly)

Note: eInvalidInput - I hadn't typed anything, the DLL was still loading.

The culprit ... The localized or underscored English command name; must be 64 characters or less in length. Actually, I make it 63 or less, I tested it, 1 character at a time.  

Verbosity killed my cat.
