Error conflict when installing 8.1 - please help
posted

Currently using v7.1 (asp.net)

Just installed v8.1

Using Visual Studio 2008.  I now have 2 tabs for each version. (great)  When I added an 8.1 chart, 2 lines got added to my web.config file.

<add assembly="Infragistics2.WebUI.UltraWebChart.v8.1, Version=8.1.20081.1000, Culture=neutral, PublicKeyToken=7DD5C3163F2CD0CB"/>
    <add assembly="Infragistics2.WebUI.Shared.v8.1, Version=8.1.20081.1000, Culture=neutral, PublicKeyToken=7DD5C3163F2CD0CB"/>

 These 2 lines cause all of my pages with 7.1 controls to Error and the message is:

'PaintElement' is ambiguous in the namespace 'Infragistics.UltraChart.Resources.Appearance'. or another similar error about ambiguous namespaces

 When I delete the 2 lines out of web.config everything works as normal.

How do I get both versions working on my PC??

    In a single solution you can only use a single version of the DLLs.  You can have both versions installed on your machine, and in one project use 7.1 and the other 8.1 but you can't use both versions together.
