.NET4.5

Does it mean that keeping controlRenderingCompatibilityVersion=3.5 in project upgraded to 4.5 framework, will still depend on framework 3.5 ?

In other words, if i uninstall framework 3.5 will above line give error or it will still work with only 4.5 framework.

What I have tried:

I have kept following in web.config file controlRenderingCompatibilityVersion=3.5
but i am not sure if it will work when 3.5 framework uninstalled from server.

Thanks for your explanation and suggestion. As existing project is very huge for now I will kept the settings and as changing CSS and JavaScript with 4.5 compatibility will take time to develop and test application extra efforts.

Thanks Again.

The ControlRenderingCompatibilityVersion setting[^] simply activates a different code path in the .NET 4.0 code, which forces certain controls to render in the same obsolete way that they did in v3.5, ignoring the new improvements introduced in v4.

It doesn't introduce a dependency on v3.5, and your site will continue to work on a computer that doesn't have v3.5 installed.

However, you should evaluate why you need that setting, and look to modify your CSS and Javascript so that it works without that setting. The new rendering mode is much cleaner and more standards-compliant.
