WPF Package Load Failure?

Package Load Failure

Package 'Microsoft.VisualStudio.Xaml' has failed tot load properly. . . yadda, yadda, yadda.

So now what? This package is somewhat important since I was hoping to do some WPF stuff this afternoon. Tried running without it and my XAML design view is gone.

I already tried "devenv /resetsettings" from the command prompt.

Thanks, Scott

Thank you Abraham for the hint. I was missing an end tag in my .NET 2.0 x86 machine.config.

However I had already spent hours repairing, uninstalling, installing and installing service packs.

WOULDN'T IT BE NICE IF VISUAL STUDIO 2008 GAVE A "MACHINE.CONFIG" CORRUPT ERROR!

In my case the machine.config file had gotten some bad XML due to a recent installation. There were two closing tags. After we corrected the bad XML, .NET works just fine.

In my case, just reinstalling SP1 didnt worked

Then i saw ive had two languages mixed in the IDE. So ive checked the installed programs and found:

  • Microsoft Visual Studio Tools For Applications 2.0 ENU
  • Microsoft Visual Studio Tools For Applications 2.0 Language Pack - ESN

When ive uninstalled the additional pack, the design views started to work again

Install SP1: http://www.microsoft.com/downloads/details.aspx?FamilyId=FBEE1648-7106-44A7-9649-6D9F6D58056E&displaylang=en

I had this problem after a fresh install of VS2008 Team System. Tried loading the updates, running setup, re-installing. No luck.

Installed SP1 and bingo! No more package load failures.

I had this problem when I installed Visual Studio Professional.

My theory was that it was because I already had Visual C# 2008 Express Edition installed.

Once I uninstalled both then reinstalled Visual Studio Professional it worked.

This is consistent with the OP's solution, which was to uninstall anything else which implemented XAML functionality.

I -FINALLY- saw this error going into Tools|Options|Environment Fonts and Colors after trying everything I could think of to get it not to crash when I chose Tools|Import and Export Settings.

Try repairing the install.

  • Control Panel
  • Add Remove Programs
  • Select Visual Studio 2008 and choose "repair"

Did you recently install any updates to Visual Studio or any Add-Ins? If so can you please list them?
