Error Connecting to Undo Manager of Source File XYZ

Question

I've been getting an error recently while debugging an ASP.NET application in Visual Studio 2008:

'Error connecting to undo manager of source file XYZ'

Any idea how I can get rid of the error?

Answer 1

Wouldn't you know it; just after I post this I find a workaround in Scott Hanselman's Blog, in the comments:

1) Right-click the designer file and select delete

2) Right-click the aspx file and select Convert to Web Application

Thanks to Matthew, whomever you are.

Answer 2

Even simpler:

My experiment consisted of simply opening the designer.cs file, typing a character somewhere in the file, deleting the new character, saving the file and recompiling.

Found on That One Developer Blog and it worked perfectly for me.

Answer 3

Open desiner.cs file Type some text in it Delete the text you have typed. Save and build the application.

Answer 4

Closing the solution and deleting the Temporary ASP.Net files directory fixed this for me. [link]

Answer 5

this one has worked for me:-- "Open desiner.cs file Type some text in it Delete the text you have typed. Save and build the application"
