# ASP.NET 

### Troubleshooting 

#### 'WebForm_DoPostBackWithOptions' is undefined in IE1 

Probleem: [How to get your ASP.NET application working in IE11](http://blogs.telerik.com/aspnet-ajax/posts/13-12-19/how-to-get-your-asp.net-application-working-in-ie11)

Fix: [App_Browsers](http://www.shubho.net/2011/01/what-is-appbrowsers-folder-in-aspnet.html) folder aanmaken in uw webapp en een `.browser` file toevoegen:

```xml
