Hi guys,
I’d really appreciate a fix for this. I use Microsoft Visual Studio 2010, and I seem to be unable to drag and drop my custom Team Foundation Build Activity from my toolbox onto the XAML build process template.
My program settings seem fine.
What is the problem behind this?

Hi Alexander Mitchell,
I have  seen a lot of possible reasons and solutions in regards with your concern. I have attached some links of good sites that gives some best possible solution with it.
Stack Overflow: activity could not be loaded because of errors in the XAML
Social MSDN Microsoft: Activity could not be loaded because of errors in the XAML
Hope that is was very useful.
Thanks and more powers.
