DrawUserPrimitives with GraphicsBuffer

i recently tried to draw some lines using DrawUserPrimitive method, but in the last DirectX (assembly 2.0) they changed this function and now i must send GraphicsBuffer data to draw the vertices, i don′t know how to use it, i looked other web pages and found tips, like this:

GraphicsBuffer<PositionColored> gb =new GraphicsBuffer<PositionColored>(3);

gb.Write(vertices);

but it doesn't compile, it sends this:

Error 3 "The non-generic type 'Microsoft.DirectX.GraphicsBuffer' cannot be used with type arguments "

what can i do? please help
