Multi-line ASP.Net TextBox spacing changed when using AntiXSSEncoder
Scope
Minor
Version Introduced
4.5
Source Analyzer Status

Change Description
In .NET Framework 4.0, extra lines were inserted between lines of a multi-line text box on postback, if using the xref:System.Web.Security.AntiXss.AntiXssEncoder?displayProperty=name. In .NET Framework 4.5, those extra line breaks are not included, but only if the web app is targeting .NET 4.5
- Quirked
- Build-time break
Recommended Action
Be aware that 4.0 web apps retargeted to .NET 4.5 may have multi-line text boxes improved to no longer insert extra line breaks. If this is not desirable, the app can have the old behavior when running on .NET Framework 4.5 by targeting the .NET Framework 4.0.
