It appears that the old issue in VS2010 where the .ascx.g.cs file does not generate after a certain number of characters in the .ascx file is reached, is back in VS2012.

Create a visual web part project (appears to be an issue in both sandboxed and farm projects). Start adding controls to the user control.
After a certain point, the designer stops generating the .ascx.g.cs file and the project will not build as the code cannot see the InitialiseControl method or any of the controls definewd in the user control.

So now it is NOT POSSIBLE at all to implement a Visual Web part for SP2010 in Visual Studio 2012.

One of my colleagues had the same problem yesterday. I thought it was just a random bug. However, When I came home and tried to create a fresh Visual Web part as a test, it turned out that ascx.g.cs file is not generated at all. I have installed 11.0.60610.01 Update 3 in Visual Studio 2012. I have disabled all Extensions, just in case. And yes, I would not really close this bug... I have no idea how to create a Visual Web part now.

This issue has returned again in the RTW of the Office 2013 Visual Studio 2012 Dev Tools released 2/26. This had been resolved in the preview bits.

Hi, when I am making my visual webpart multilanguage that is : when adding $Resource:filename,key in the .ascx file, the webpart starts complaining.

The issue still available. let me know if someone has this sorted out.

I experience this same bug, however in my case it isn't due to a certain number of characters, but adding <%@ Register %> or <% Assembly %> to my .ascx file immediately clears the .ascx.g.cs file. I have been able to consistently replicate this on two different SharePoint servers.

Hi Derek,

We are unable to reproduce the issue. We ran several tests in our latest builds and failed to reproduce the error.

Please install the latest updates to Visual Studio and Office Developer Tools.
