Why do I get these kind of warnings when building my exefile

[tony]

Hello!!

I use VS 2003 and C# for all class library except MeltPracCommon.dll which
is C++.NET

The problem is that I get these warnings when building the exe file and use
my class libraries.
See below for a detail description.

Warning: The dependency 'MultiLang, Version=1.0.2274.20801, Culture=neutral'

Build complete -- 0 errors, 0 warnings
Building satellite assemblies...

I have search the internet and found a lot but nothing that explains these
kind of warnings.
For example in the reference for the exe project I reference MeltPracStorage
in this way I use
C:\PK\Development\Products\UTCAS\4.0\SRC\MeltPracS torage\bin\Debug\MeltPracS
torage.dll

For example in the reference for the exe project I reference 'MultiLang in
this way I use
C:\PK\Development\Products\UTCAS\4.0\SRC\MultiLang \bin\Debug\MultiLang.dll

The exe file are using six class library dll. These are:
1. MeltPracCommon.dll is using Multilang.dll

2. Commons.dll is not using any dll

3. MeltPracStorage.dll is not using any dll

4. MMICommon.dll is using Commons

5. Multilang.dll is using MeltPracStorage.dll

6. UTCASCommon.dll is using MMICommon.dll and MeltPracStorage.dll

I have only a single project in each solution project. So a have 6 solution
project having one class library project in each one.

So in the referens list for each project I have the following.
UTCASCommon reference MMICommon and MeltPracStorage
MMICommon reference Commons
MeltPracCommon reference Multilang
Multilang reference MeltPracStorage

I use copy local = TRUE for each referece dll that I use.
There are no problems at all to build all the class library dll

In the UTCASCommon output directory I have the following after a successful
build. UTCASCommon.dll, MMICommon.dll, Common.dll and MeltPracStorage.dll

In the MMICommon output directory I have the following after a successful
build. MMICommon.dll and Commons.dll

In the Commons output directory I have the following after a successful
build. Commons.dll

In the MeltPracCommon output directory I have the following after a
successful build. MeltPracCommon.dll and Multilang.dll

In the Multilang output directory I have the following after a successful
build. Multilang.dll and MeltPracStorage.dll

In the MeltPracStorage output directory I have the following after a
successful build MeltPracStorage.dll

So can somebody explain or tell me how to fix my warnings when buiding the
exe file because
I haven't any idea.
Why do I only get warning for MeltPracStorage and Multilang and why do I get
two warnings for
MeltPracStorage
