Is it possible to run c# code compiled for .NET Core 2 at CoreCLR 3? If it is possible, will I have any benefits like better garbage collection, mentioned in the .NET Core 3 release announcement?
You will have to migrate the code to .Net Core 3. Microsoft provides migration documentation
https://learn.microsoft.com/en-us/aspnet/core/migration/22-to-30
Overall if your code is pretty basic there is likely not much for you to update.

What's the difference between .NET Core, .NET Framework, and Xamarin?

I have navigate to https://www.microsoft.com/net/download/windows
to download .net core SDK , then i saw there is 3 build apps
.Net Core
Visual Studio
.NET Framework Develop Pack
Can anyone explain what is the difference between 1st one and 3rd one ?
The first is .NET Core which is a smaller subset of the .NET framework. .NET Core was largely for web apps and web workers, but it was announced yesterday that soon .NET Core will support desktop applications as well. Not all assemblies are available in Core, but it has a smaller package size and will run on any platform.
.NET Framework is the one people usually refer to when they say ".NET", which is the full-featured framework that is used to build VB.NET and C# applications.
A great read about the difference in use for server applications (which is where the real details lie) can be found here.

Configuring .NET Framework 4.5.2 in IIS 8.0
(2 answers)
Closed 7 years ago.
I have an old website, it is not web application so there is no properties window to target the .NET Framework to 4.5.2, how do I modify the web.config to target .NET Framework 4.5.2?
I need to know that it uses .NET 4.5.2 because I want to test whether the application is compatible with it before deploying to production
Right click on the web project and select the Application tab on the left. There is an option for Target Framework: It will probably be set to 4.5 or 4.5.1. Change it to 4.5.2 and repeat for any other projects in the solution.

Version Information on ASP.NET Server Error Page
(1 answer)
Closed 7 years ago.
I am implementing an MVC 5 website in C# (VS 2013 update 4) and the build setting is targeting .NET framework version 4.5. However when I load the page, I see the following header entry:
X-AspNet-Version:4.0.30319
Why is the website running under .NET 4.0xxxx despite the compile setting is pointing to .NET 4.5? Any ideas?
Thanks in advance.
That is not the actual .NET framework version. It is the version of the CLR.
From .NET 4 up to 4.5.2 it is version 4. Between 2.0 and 3.5 it was version 2.0.
That is also the reason that in your application pool configuration you can only choose .NET 2 or 4.
See MSDN: .NET Framework Versions and Dependencies on this matter.

You can check to see if this line returns a version number higher than "3.0.1" :
return System.Diagnostics.FileVersionInfo.GetVersionInfo(#"C:\Windows\System32\msi.dll").ProductVersion;
