I am now getting errors relating to
"Found conflicts between different version of the same dependent assembly"
I install the service release. noted above.
Do I have to remove and all the infragistics references? run the project upgrader?
You need to make sure that all of the project references are changed to use the same, new version. The project upgrade utility should do that for you.
I tried the project upgrade utility it did not work. It did not modify the licenses.lix files. so i had to remove and readd the control references then i had to manually modify the version number in the licenses.lix file.
