Microsoft ASP.NET will now emit a SameSite cookie header when HttpCookie.SameSite value is “None” to accommodate upcoming changes to SameSite cookie handling in Chrome. As part of this change, FormsAuth and SessionState cookies will also be issued with SameSite = ‘Lax’ instead of the previous default of ‘None’, though these values can be overridden in web.config. You have to set the cookieSameSite= “None” in the session state tag to avoid this issue. I have tried this and working well. https://social.msdn.microsoft.com/Forums/en-US/1b99630c-299c-446e-bf4b-d7d4d74bf9ef/problem-with-session-in-iframe-after-recent-windows-update?forum=aspstatemanagement

You can modify this value directly in applicationhost.config. 1) Select the site under Default Web Site 2) Select Configuration Editor 3) Within Section Dropdown, select “system.webServer/serverRuntime” 4) Enter a higher value for “uploadReadAheadSize” such as 1048576 bytes. Default is 49152 bytes. During client renegotiation process, the request entity body must be preloaded using SSL preload. SSL preload will use the value …

Asp.net menu control not working on Google Chrome
To solve this you will need to tell .net the capabilities of the browser. For .net 2.0 & above you need to create a new browers file with the capabilities and upload it to your server. In VS2008 Solution Explorer right click your application and add the “ASP.Net Folder” App_Browsers if you don’t already have it.

ASP.NET 2.0 – Enter Key – Default Submit Button
One of the most annoying things in developing web pages is handling the “Enter key” for form submission. Enter key has been the favourite way users like to submit forms. Though we provide Buttons to click on, the easiest and intuitive way is that, I can enter some text, make some changes and then hit “Enter” to accomplish my submission. “Enter” Key is handled in a little tricky way by uplevel browsers like Internet Explorer, when it comes to ASP.NET. * If there is a single Textbox and single button, then it becomes straight forward, the button is submitted. However, …
problema com asp:menu no IE8
O internet explorer 8 se tornou muito, muito mais compatível com os padrões W3C do que as versões anteriores. A diferença foi tanta que o IE 8 precisou criar o modo de compatibilidade, para que páginas que ainda não são totalmente compatíveis com este padrão possam continuar funcionando. Desenvolvedores podem configurar seus sites para serem sempre rodados em modo de compatibilidade Até mesmo o mais inesperado foi atingido pelas mudanças no IE 8 : O webcontrol de menu nativo do ASP.NET não encontrava-se 100% compatível com o W3C e consequentemente os sites que utilizam o webcontrol de menu apenas continuarão …
