如何在运行应用程序时强制使用特定的 .Net 版本（低至次要/次要版本号）

Question

I have installed different versions of the.Net framework on my machine and I wonder if it is possible to choose one specifically when running a.Net app.

I tried setting it in App.config like so:

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />

but when I check the version being actually used via RuntimeInformation.FrameworkDescription , the output is .NET Framework 4.8.4261.0 , even though v4.6.1 is installed on my system.

How can one test a specific version, eg to see whether a bug shows on a particular.Net version?

Answer 1

You could specify the .NET Version for your application by changing it in your application propreties, in Visual Studio right-click on your project and then propreties, under Application tab.

Then Visual Studio will update config files automatically.
