Integrate Web Service in SQL Server assembly

Question

Hi,
I need to create an assembly in SQL Server 2010 who integrate a web service reference. What I did so far:
1) Create a SQL CLR database project in VS 2010
2) Add a Web Service reference. Service is added correctly and methods are exposed.
3) Add a StoredProcedure with code with reference to the web service. 
4) Build. 
Then I tried to create the assembly in SQL with 'Create Assembly FROM 'DLL PATH' ' but I get the error:
Assembly 'MaestroInterface' references assembly 'system.servicemodel, version=3.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089.',
which is not present in the current database. SQL Server attempted to locate and automatically load the referenced assembly from the same location where referring assembly came from, but that operation has failed (reason: 2(failed to retrieve text for this
error. Reason: 15105)). Please load the referenced assembly into the current database and retry your request.
Even if I try to add the System.Servicemodel DLL, I get another missing DLL.
Have I done something wrong? How can I fix this?
thanks for your time and help

My assembly registered fine in SQL, but I still struggle with a problem. The method of the Web Service returns XML. As soon as I do a call to one of those method, it crashes:
Cannot load dynamically generated serialization assembly. In some hosting environments assembly load functionality is restricted, consider using pre-generated serializer. Please see inner exception for more information. ---> System.IO.FileLoadException:
LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.
I looked on internet and find the page:

So I created the XMLSerializer with sgen and created the assembly in MSSQL. Still, it gives me the same error.
I'm using SQL 2008 R2 and CLR assembly is made using VB 2010, framework 2.0. sgen has been executed in VS Command prompt of VS 2005
