The name “Canvas” does not exist in the namespace
Quick Tips:
For those of you who are developing/designing using Blend 2 Aug Preview and Orcas B2 (Visual Studio 2008 B2) getting errors as such:
1. The name “Canvas” does not exist in the namespace
2. The name “TextBlock” does not exist in the namespace
You need to upgrade your Blend version from https://www.microsoft.com/expression/products/download.aspx?key=blend2preview
Cheers!
