You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5

Last Thursday, our team was trying to deploy a .NET app on a Windows Server 2008 R2 server. Our server admin was instructed to install Visual Studio 2008 to ease the debugging on the server side but during installation, the setup prompted an error message of "You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5".



You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5

After several minutes of researching online, we found the answer. Windows 2008 R2 already ships with the .NET 3.5.1 framework so you just need to enable the feature from Server Manager.



So before installing the Visual Studio 2008, we enable the .NET 3.5.1 framework feature from the Add Features Wizard in Server Manager.

Thanks Fryan. I love how it says "Role Management Tool",but it's actually a "Feature" that you need to enable.

Sigh ....

Feb 26, 2012 thanks to a bing search your post saved me from hours of "what the heck??". You would think that years later Microsoft would provide just a bit more clarity to their messages.
