Intellisense not working for XAML in VS2012 and only partially in Blend

intellisensevisual studio 2012xaml

I'm trying to get RC of Visual Studio 2012 working for XAML files. I can't seem to get any XAML Intellisense and the option within Tools is greyed out.

I've also tried to run the solution using Blend, however I only get Intellisense for custom controls such as telerik then.

Partial Intellisense in Blend

When ever I drag controls onto the design surface I get an "Object reference not set to an instance of an object" exception but the control is still added to the surface.

I've read that this was a bug within VS11 and was fixed with in the Visual Studio 2012 RC.

I've created a new Silverlight Application and the intellisense is working so i'm wondering if its an issue with how my projects are set up.

I have all of my Styles within a separate themes project, which is referenced by other all other projects. Within the designer these references show up as errors but when the application runs they are resolved fine.

Would unresolved resources at design time affect Intellisense?

Click "Build -> Clean Solution", then "Build -> Build Solution". ("Rebuild Solution" alone doesn't work.) [Source]

Visual-studio – Error ‘LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt’ after installing Visual Studio 2012 Release Preview

This MSDN thread explains how to fix it.

To summarize:

Either disable incremental linking, by going to

Project Properties 
   -> Configuration Properties 
       -> Linker (General) 
          -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"

or install VS2010 SP1.

Edits (@CraigRinger): Note that installing VS 2010 SP1 will remove the 64-bit compilers. You need to install the VS 2010 SP1 compiler pack to get them back.

This affects Microsoft Windows SDK 7.1 for Windows 7 and .NET 4.0 as well as Visual Studio 2010.

Asp.net-mvc – Visual Studio debugging/loading very slow

Here is how I solved the "slow symbol loading" problem in Visual Studio 2012:

Go to Tools -> Options -> Debugging -> General
CHECK the checkmark next to "Enable Just My Code".
Go to Tools -> Options -> Debugging -> Symbols
Click on the "..." button and create/select a new folder somewhere on your local computer to store cached symbols. I named mine "Symbol caching" and put it in Documents -> Visual Studio 2012.
Click on "Load all symbols" and wait for the symbols to be downloaded from Microsoft's servers, which may take a while. Note that Load all symbols button is only available while debugging.
UNCHECK the checkmark next to "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.
Click "OK".

From now on, symbol loading should be much faster.

Note that if you make any changes/downloads to Microsoft assemblies, you may need to go back into the Symbols dialog box and "Load all symbols" again.
