Run dot net 3.5 application on Windows 10

Question

I have created a WPF application which should natively run on Windows 7, 8, 8.1, 10.

In Visual Studio, I have set .NET Framework to 3.5 as it is bundled with Windows 7. When I run it on Win10, however, it prompts to install .NET 3.5 as Win10 is bundled with 4.6 and does not have 3.5 installed by default.

How can I make my application run on all Windows versions >= 7 without getting any prompts from Windows and without installing anything?

Answer 1

IT CAN WORK, found the solution:

We need to modify app.config file and put below lines in it:

<startup>
 <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
 <supportedRuntime version="v4.0"/>
 <supportedRuntime version="v2.0.50727"/>
</startup>

It decides from top to bottom, whichever first version of .net is found as per above list it works on that.

CATCH: After building, a ProgramName.exe.config file is made in release folder, we need to copy it with our ProgramName.exe to the system in which we want to run..

Answer 2

You can create an installer that installs your app + .NET 4.5 to client's computer silently. That way your app will run seamlessly on every OS.
