Workaround: Installing Win SDK after VS2008 breaks XAML Intellisense
Several VS 2008 and Windows SDK users have reported that Intellisense stops working for XAML projects after installing the Windows SDK for Windows Server 2008 and .NET Framework 3.5.
The Windows SDK Team and the Visual Studio 2008 team has been able to repro the issue and the cause has been identified. A Visual Studio registry value is being incorrectly reset after the Windows SDK is installed, causing this failure.
How to determine if you are experiencing this issue
1. Please review the article, Windows registry information for advanced users before using regedit.
2. Using regedit, look at the key:
· On X86 machines: HKEY_CLASSES_ROOT\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32
· On X64 machines: HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32
3. If (Default) is empty you are experiencing this issue
We suggest two workarounds: repair Visual Studio 2008 or register TextMgrP.dll manually.
Repair Visual Studio 2008:
1. From the Start button, open the Control Panel
2. Click on Program and Settings (Add/Remove Programs on non-Vista machines)
3. Click to select Visual Studio 2008 and click Change (at the top of the window)
4. When the change dialog box launches, select Repair
Register TextMgrP.dll manually
On an X86 machine:
1. Open a Windows CMD window as an Administrator (On Vista: Start, All Programs, Accessories, right-click on command prompt and choose to Run as Administrator)
2. Type: regsvr32 "%CommonProgramFiles%\Microsoft Shared\MSEnv\TextMgrP.dll”
On an X64 machine:
1. Open a Windows CMD window as an Administrator (On Vista: Start, All Programs, Accessories, right-click on command prompt and choose to Run as Administrator)
2. Type: regsvr32 "%CommonProgramFiles(X86)%\Microsoft Shared\MSEnv\TextMgrP.dll”
Restart Visual Studio and Intellisense should be working correctly again.
