I have upgraded projects to .net framework 4.0 (VS 2010) and I am getting lots of “The server tag is not well formed”.
for example,
validationgroup=”Check has missing closing double quot.
ValidationExpression=”[^\”\’]” — I had to convert that to ValidationExpression=”[^& q u o t ; ‘]” to make it work.
We have many dozens of web projects and I can go through each of this and correct those things. This was working fine with VS 2008 (framework 2.0) so I was wondering is there any settings to turn off this kind of validation when compiling the project?
I have tried turning off HTML Validation (Tools -> Options -> Text Editor -> HTML -> Unchecked show errors) even though it shows me those error.
Any help would be appreciated.
The page parser became stricter in ASP.NET 4.0. You can review details of this and other “breaking changes” that occurred in the newest version on the ASP.NET 4 Breaking Changes page.
