Hi,
we need some information why when in any filed in a Form on Microsoft Portals when adding the following character format "<test> test" with the combination of < > and just some text in between we generate the following error:
Server Error in '/' Application.
A potentially dangerous Request.Form value was detected from the client (ctl00$ContentContainer$EntityFormControl_9da592ee63ede811a965000d3ab1ab19$EntityFormControl_9da592ee63ede811a965000d3ab1ab19_EntityFormView$title="<test> test").
Description: ASP.NET has detected data in the request that is potentially dangerous because it might include HTML markup or script. The data might represent an attempt to compromise the security of your application, such as a cross-site scripting attack. If this type of input is appropriate in your application, you can include code in a web page to explicitly allow it. For more information, see go.microsoft.com/.../
