Installing WCF/WPF Extensions for VS 2005 after .NET Framework SP1

How to install WCF/WPF Extensions for Visual Studio 2005 if you've already installed .NET Framework 3.0 SP1?

If you have .NET Framework 3.0 SP1 installed on your machine, when attempting to install the Extensions - you'll get an error message saying:

Setup has detected that a prerequisite is missing. To use Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), November 2006 CTP you must have the .NET Framework 3.0 runtime installed. Please install the .NET Framework 3.0 runtime and restart setup.

Now, apparently .NET Framework 3.0 SP1 is not .NET Framework 3.0 for the Extensions installer.

Seems like the best way to go around this problem is to fool the Extensions installer by putting a fake key into the registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{15095BF3-A3D7-4DDF-B193-3A496881E003}]
"DisplayName"="Microsoft .NET Framework 3.0"

 

Worked for me! :)

Could not find file 'Microsoft.Windows.CommonLanguageRuntime, Version=2.0.50727.0'

When the compiler cannot find the Common Language Runtime, you can become confused...

I recently made some uncontrolled move with my mouse while holding down its left button over the Solution Explorer in Visual Studio - it sometimes just happens, you know... (too much coffee???)

Anyway - I knew something happened, because noticed that the window blinked and looked like digesting something for a second or two... I tried to find some file moved into some strange folder or something, but could find anything like that - so I just continued to write code.

And then - after a few minutes, when I hit Ctrl+Shift+B - I got this error:

Could not find file 'Microsoft.Windows.CommonLanguageRuntime, Version=2.0.50727.0'

Excuse me? Come again (I hit Ctrl+Shift+B once more)?!?

Yeah, apparently the CLR had been uninstalled - oh, no problem, happens every other day, right?

Seriously - the error did not want to go away, and (of course) it was the worst moment for something like that to appear, so I started googling... and found out, that it actually does happen - well, not the uninstallation of the CLR, but the error message.

The cause of the error message is this:

If I activate the "Enable ClickOnce Security Settings" [in Project Properties] I get the error, if I disable this feature it compiles correctly.

Perfectly reasonable, eh?

Anyway - the real question is now - what kind of crazy jerk must I have done with my mouse to turn that option on???
