Generation of designer file failed: Could not load file or assembly

Question

I have an ASP.NET web application project which references another project called ModusCore (or Modus.Core). We\'ve had a variety of controls that use ModusCore up until now wi

Answer 1

Adding a third option for when @scherand's (a) and (b) fail:

c) "Sometimes", this works as well:

• Remove the <%@ Register... %> entries
• Save the .AS?X file. Let the designer complain.
• Add the <%@ Register... %> again
• Save again

d) "Sometimes", as well:

• Clear the AS?X file off all but the most basic content.
• Start adding pieces back, one bit a time.
• Save.
• Check that you didn't get the error message.
• Add back a few more pieces. Rinse. Repeat.

I use a text comparison tool against a back up copy of the AS?X file for this.

I try to avoid adding the controls that cause the error until the very end. I also try to add from the bottom of the page. However, I don't know of a hard rule. It's a gut-feeling exercise.

(Will someone ever figure this one out?)
