I'm in Visual Studio trying to use a table adapter (from a xsd file in the App_Code folder). I've tried remaking it multiple times with various different names too.
For example, I currently have "PleaseWork.xsd" in my App_Code folder. In the codebehind for a page I've got using PleaseWorkTableAdapters;
at the top. It's telling me the namespace could not be found for some reason.
Checked the actual code for the xsd file too and it's got this at the top so the name I used should be correct
<xs:schema id="PleaseWork" ...
After various restarts of Visual Studio, cache deleting, and other things, updating ReSharper from 2017.1.3 to 2017.2 is what fixed the problem.
