Hi Josef Zelinka,

Are you using any XAML in your project? If so, please check if there any syntax errors with XAML - which could also throw the aforementioned error.

Hi Josef

As we know, Visual Studio has backward compatibility, if you create asp.net web form project in Visual Studio 2012, you can open it in Visual Studio 2013.

According to error message, I'm not sure the root of this issue. For this issue, I'd like to suggest you to recover your modification.

Hi Angie,

I have no problem with open VS 2012 project in VS 2013.

My problem has this scenario:

1. Open project in VS 2013 - OK

2. Open aspx / ascx file - ok

3. Add server control e.g. Literal to aspx/ascx

4. Save aspx / ascx - I get this error

I am having the same problem, and this solution also did not work for me. I have resharper installed, and after I disabled resharper, the error went away. I haven't figured out why resharper is affecting it, but at least I can work again.

Hi,

Please try delete the project cache and reinstall as advised below: http://rathodkrunal.blogspot.com/2011/11/visual-studio-2010-error-hresult-efail.html
Please note: I've not encountered this problem and neither ran the above command earlier. However, hope this solves your issue.

Good luck!

I'm having the same problem. I tried adding a classname to the aspx page

<%@ Control Language="C#" AutoEventWireup="true" ... ClassName="GeneControlPage"%>

then restarting Visual Studio, and it SEEMS to be working.

I got this off of the JPHellemons web site, although the link above seems to be working. It may just be me, but VS2013's web tools seem to be awefully fragile. It seems to break if I so much as look at it funny.

(And my project/solution doesn't use XAML or Silverlight, either.)

And that was just a short term fix. Deleting the cache didn't help either.

Gah.

Have you attempted to restart Visual Studio (and try running it as an Administrator; Right-click > Run as Administrator) or Clean and Rebuild your current solution (Right-click > Clean Solution) to see if that makes any differences?

If the application itself isn't that complex, you might consider posting the code relating to it to see if we could easily reproduce the issue.

Cleaning the cache worked for me, finally. It's not where Siva pointeed to.

The cache(s) live in

C:\Users\<<Your Alias>>\AppData\Local\Microsoft\Team Foundation

C:\Users\<<Your Alias>>\AppData\Local\Microsoft\VisualStudio

C:\Users\<<Your Alias>>\AppData\Local\Microsoft\VSCommon

and afterwards you need to run Visual Studio  with the  /resetuserdata switch. Be warned that this will wipe ALL of your settings.

(Running as administrator and cleaning the project didn't help, btw.)
