Bounty: I will send $5 via paypal for an answer that fixes this problem for me.

I'm not sure what VS setting I've changed or if it's a web.config setting or what, but I keep getting this error in the error list and yet all solutions build fine. Here are some examples:

Error   5   'CompilerGlobalScopeAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'. C:\projects\MyProject\Web\Controls\EmailStory.ascx  609 184 C:\...\Web\
Error   6   'ArrayList' is ambiguous in the namespace 'System.Collections'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   13  28  C:\...\Web\
Error   7   'Exception' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   37  21  C:\...\Web\
Error   8   'EventArgs' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   47  64  C:\...\Web\
Error   9   'EventArgs' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   140 72  C:\...\Web\
Error   10  'Array' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   147 35  C:\...\Web\

    [...etc...]

Error   90  'DateTime' is ambiguous in the namespace 'System'.  C:\projects\MyProject\Web\App_Code\XsltHelperFunctions.vb   13  8   C:\...\Web\

As you can imagine, it's really annoying since there are blue squiggly underlines everywhere in the code, and filtering out relevant errors in the Error List pane is near impossible. I've checked the default ASP.Net web.config and machine.config but nothing seemed to stand out there.

Edit: Here's some of the source where the errors are occurring:

'Error #5: whole line is blue underlined'
<%= addEmailToList.ToolTip %>

'Error #6: ArrayList is blue underlined'
Private _emails As New ArrayList()

'Error #7: Exception is blue underlined'
Catch ex As Exception

'Error #8: System.EventArgs is blue underlined'
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

'Error #9: System.EventArgs is blue underlined'
Protected Sub sendMessage_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles sendMessage.Click

'Error #10: Array is blue underlined'
Me.emailSentTo.Text = Array.Join(";", mailToAddresses)

'Error #90: DateTime is blue underlined'
If DateTime.TryParse(data, dateValue) Then

Edit: GacUtil results

There should only be one mscorlib in the native images, correct? How can I get rid of the others?

Based on the results of your gacutil output (thanks for doing that; I think it helps), I would say you need to try and run a repair on the .NET Framework install and Visual Studio 2005. I'm not sure if that will fix it, but as you can see from the output of the gacutil, you have none for 2.0.

From my VS2005 Command Prompt, I get:

I've been hit by this as well, specifically System.Data.SqlClient. Try unchecking namespaces in the Project manager and manually including them in the .vb file, like you would with C#:

Imports System.Data.SqlClient
