The C# Express SKU of VS is very limited and I dont see a reason why I shouldn't be able to run XNA on my Pro version of VS.

Here is a magic registry file that will allow you to use XNA with VS Pro:

-------------------------- REG BEGIN
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\InstalledProducts\XnaPackage]
"Package"="{3f844fae-e70b-4d9e-ab20-b5f39c86d795}"
"ProductDetails"="#102"

"LogoID"="#400"
@="#100"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Projects\{9f340df3-2aed-4330-ac16-78ac2d9b4738}]
"Package"="{3f844fae-e70b-4d9e-ab20-b5f39c86d795}"
@="XnaProjectFactory"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{3f844fae-e70b-4d9e-ab20-b5f39c86d795}]
"InprocServer32"="C:\\WINDOWS\\system32\\mscoree.dll"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\NewProjectTemplates\TemplateDirs\{3f844fae-e70b-4d9e-ab20-b5f39c86d795}]
@=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\NewProjectTemplates\TemplateDirs\{3f844fae-e70b-4d9e-ab20-b5f39c86d795}\/1]
"SortPriority"=dword:00000064
@=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\CLSID\{d4646d23-7d26-42d2-ac0c-4af99e818f68}]
"InprocServer32"="C:\\WINDOWS\\system32\\mscoree.dll"
"Class"="Microsoft.Xna.VisualStudio.Framework.XnaProject"
"Assembly"="Microsoft.Xna.VisualStudio.Framework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f48fa5f25d27e8ff"
"ThreadingModel"="Both"
@="Microsoft.Xna.VisualStudio.Framework.XnaProject"

-------------------- REG END

After importing thes keys you must run: devenv.exe /setup


Hope It helps somebody.
