The Visual Studio Error List shows like 50 errors about controls and variables not existing. I double click an error, it takes me to it, and after about 1 second they all go away!
There aren't any real errors, as my site compiles without errors or even warnings.
I know I've seen this before, but I forget how to fix it. Anyone know why this is happening? Thanks in advance!
I've seen this before but I'm not sure what the actual cause is. I've seen it most using a website ASP.NET project rather than a web application ASP.NET project, but I don't know for certain that that's the cause.
That said, in my opinion you should use a web application style project anyway as it will pre-compile the most important portions of your application before deployment.
I see it often too on web sites. I always have chalked it up to the compiler needing to "catch up" although I'm sure there is a more sophisticated answer to why that happens. It's annoying.
The solution to this problem:
open the *.aspx.cs page and after about 1 second they all go away
