When trying to add a Data Connection in Server Explorer, the following error occurs:

Package Load Failure

Package 'MySQL Connector Net 5.2.0' has failed to load properly ( GUID = {79A115C9-B133-4891-9E7B-242509DAD272} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading.

How to repeat:
Open Visual Studio 2008 (any version)
View -> Server Explorer
Rightclick on the "Data Connections" node and choose "Add connection..."

The error will then appear.

We're still trying to sort out the problem.  Did you have a version of Connector/Net installed prior?  What OS is this?  VS2005 installed?

No, this is in fact a quite fresh installment of Vista (Ultimate), so no prior Connector/Net installation was ever on this system. VS2005 is also not on this one, but in my office i got all three (2k3, 2k5 and 2k8) installed.

On my office box i had 5.1.x installed first, which worked fine on 2k3 and 2k5, but of course didn't have any support for 2k8. Then i removed 5.1 and put on 5.2, finding 2k5 still working, but 2k8 giving me that error.

I have the same problem.
My config is :
Win XP Pro SP2 (french)
Wisual Studio 2005 Pro (english)
Wisual Studio 2008 Pro (english)

During the installation VS 2008 was running.

Then i tried to unistall it and re install it when the VS 2008 was closed

I allways have the same error

fixed in 5.2.1
[1 Mar 2008 10:20] MC Brown
A note has been added to the 5.2.1 changelog: 

The installer would fail to the DDEX provider binary if the Visual Studio 2005 component was not selected. The result would lead to Connector/NET not loading properly when using the interface to a MySQL server within Visual Studio

This bug still happens for me -- even with version 5.2.4
Tried on new computer with fresh install of vs2008 and mysql 5.0 and connector 5.2.4
When I tried to connect to database --> 'Package Load Failure' ...
