You are attempting to access a member which is marked as 'Shared' using a
reference referencing an instance of the type. Instead, simply write '<type
name>.<member name>'.

I just want to make a comment, I am not sure what the error refers to,
however, I have seen similiar warning signs on some of the programs I
have written. Example, If I want to sort an array, I would assume I
could use syntax such as:
MyArray.Sort(My Array)
This would cause the same warning that you have mentioned, but if I
change my syntax to something like:
system.Array.So rt(MyArray) and the error warning would go away.
I personally think its a coding issue, you might want to check to see
if both of your programs are referencing the same NameSpaces (import
statements).

MyArray.Sort(My Array)
system.Array.So rt(MyArray) and the error warning would go away.
The difference in these statements is that MyArray is a variable, so it may
be nothing and null reference exception occurs. Of course, this is a bad
example since the same variable is used as parameter as well, so an
exception would actually be thrown in both cases, but you got the point?

Note that 'Array.Sort' is a shared method, so it can eben be called on a
'Nothing' reference.

Well, thanks for correcting. This ain't my first time being wrong. I have

You are attempting to access a member which is marked as 'Shared' using a reference referencing an instance of the type. Instead, simply write '<type name>.<member name>'.
You are probably seeing the FxCop rules being run where they aren't run on
your other computer's IDE (pre 2005 or without the Code Analysis turned on
in the project).
Here's an explanation of the issue. Let's say you have a class called foo
with a shared method bar as follows:
Public Class Foo
Public Shared Sub Bar()
'Do Something
End Sub
End Class
Now, lets consider how you call this method. You can not have a calling method
that calls Bar on an instance of Foo as follows:
Public Sub Main()
Dim instance as new Foo
instance.Bar 'This is invalid
End Sub
Instead, you need to call Bar directly without an instance as follows:
Public Sub Main()
Foo.Bar()
End Sub
Sometimes, you can end up with conflicts in namespaces and although you think
you are calling the shared method directly, you are trying to call it from
an instance as follows:
Public Sub Main()
Dim foo as new Foo
foo.Bar() 'Incorrect
MyApp.Foo.Bar() 'Correct assuming MyApp is the namespace for the application.
End Sub
I hope this helps you understand the situation. Typically, this is a relatively
easy oversight to make and luckily fix as well.

I've read (and read!) that you shouldn't store objects in Session variables.
I've read these reasons:
- The object takes up memory that may not be freed until the session times
out. Better to create the object only when you actually use it.
- Causes poor performance because the thread that created the object has to
service all requests for it.

Some of the classes in the framework are marked as thread-safe in the
documentation. In particular the docs say the following:
"Any public static (*Shared* in Visual Basic) members of this type are
thread safe. Any instance members are not guaranteed to be thread safe."
What exactly does this mean? Does this mean that if I call a shared
method from 2 different threads, nothing whacky will happen?
Also when it says that instance members...

members of this type are safe for multithreaded operations. Instance
members are not guaranteed to be thread-safe.
I'm under the impression before you can use a class you have to make an
instance of it. So how can a class be threadsafe by itself but an
instance of it not be?
I guess I don't get what exactly being threadsafe means. Multiple
theads can use the same instance of a class?
