i made a reference on it, but it doesn't help

the exception text is:

Also try calling the Matrix objects as Bluebit.MatrixLibrary.Matrix

-the bluebit dll has to be icopied to the startup directory (where the program exe is located.

- the bluebit license-file has to be there, too.

a program line like : Matrix M = new Matrix() doen't show any effect,

a program line like: Matrix M = new Matrix(2,2) throws the exception as described above.

when the exception is thrown and i use debug single step (Mixrosoft visual studio 8) the license form is opened.

I enter the required license key, and, after that, everything works; no exception is thrown any more.

Using the full path makes it possible to distinguish Bluebit.MatrixLibrary.Matrix from System.Design.Matrix .

the exception still occurs whenever for the first time

a line like Matrix M = new Matrix(n,n) occurs.

it definitely diesn't have anything to do with the usage of a fully qualified name like

Bluebit.MatrixLibrary.Matrix !

I guess, something goes wrong when your library checks for a valid license.

==================================================

i guess, only during licence-check the bluebit software accidentally makes a reference to System.Design.
But including a reference in the main programme to System.Design doesn't help.

i made some exploration concerning this error and found a hint in:

>>> quotation
.NET Framework Developer's Guide
Diagnosing Errors with Managed Debugging Assistants:
Managed debugging assistants (MDAs) are debugging aids that work in conjunction with the common language runtime (CLR) to provide information on runtime state. The assistants generate informational messages about runtime events that you cannot otherwise trap. You can use MDAs to isolate hard-to-find application bugs that occur when transitioning between managed and unmanaged code. You can enable or disable all MDAs by adding a key to the Windows registry or by setting an environment variable. You can enable specific MDAs by using application configuration settings. You can set additional configuration settings for some individual MDAs in the application's configuration file.
.....
When your code is executing in the Visual Studio integrated development environment (IDE), you can avoid the exception dialog box that appears for specific MDA events. To do that, on the Debug menu, click Exceptions.In the Exceptions dialog box, expand the Managed Debugging Assistants list, and then clear the Thrown check box for the individual MDA.
>>> end quotation

so, in my visual studio 8, i opened debug -> exceptions -> Managed Debugging Assistants
and removed tracking of exception : "BindingFailure".
Now no exception is thrown anymore.

Nevertheless, i think, you should check the code for the licence-checking procedure.
Maybe, you can reproduce the effect by:
-use visual studio
-set a check at debug -> exceptions -> Managed Debugging Assistants -> "BindingFailure".
-run your program within visual studio

My interpetation of the error is different. The licensing mechanism, the first time a license file is used, it opens a form (using System.Design) in order to activate the new license file.

In your system the assembly containing the System.Design namespace cannot be reached so this raises the above error. You could try printing the stack trace info just to see the procedure calls.

Can you please verify that .NET Framework version 2.0 is installed on your machine?

The licence-form opened and i could enter the licence-key.

how can i get the stack trace info ?

i have installed Framework 1.1, 2 (with all patches), 3 and 3.5

Is .NET Framework 2.0 installed on the machine running NML?

If yes then you shouldn't need to copy System.Desing.dll to the application directory since it should be found in the GAC.
