I have a .net 3.5 application with mvc2.0 used.
Will it work in a server with 4.0 with mvc2.0 with out .net 3.5 framework?
Do I need to make any changes in config?

I am working on Window Application WinForms with .NET Framework 4.0. I am trying to configure microsoft.extensions.dependencyinjection but unable to sort correct compatible version. Is anyone have implemented DI with .NET Framework 4.0 app?
I am trying (unsuccessfully) to create a Console Application that targets .Net 5.0 so that I can use C# Version 9.0.
Although I have installed the .Net 5.0 I am unable to select it when creating a project.
I would like to use some of the new features of C# 9 but this requires version 5.0 of .Net as I understand it.
I am using Visual Studio 2019 Version 16.8.3
Thanks
Right click on the csproj and make sure it looks like this:
<PropertyGroup>
<OutputType>Exe</OutputType>
<LangVersion>latest</LangVersion>
<TargetFrameworks>net5.0</TargetFrameworks>
...
</PropertyGroup>
If you don't see .NET 5 in the Target Frameworks for a .NET Core Application, you don't have the installation correct. Here's what mine looks like
C# 9 is only available on .NET 5 (which is .NET Core not .NET Framework).
C# 9.0 is supported only on .NET 5 and newer versions.

.NET 5.0 is the next major release of .NET Core following 3.1. We
named this new release .NET 5.0 instead of .NET Core 4.0 for two
reasons:
We skipped version numbers 4.x to avoid confusion with .NET Framework
4.x.
We dropped "Core" from the name to emphasize that this is the main implementation of .NET going forward. .NET 5.0 supports more
types of apps and more platforms than .NET Core or .NET Framework.

Can I use 4.0 compiler to create .net 3.5 dll?
Or the minimal .net version is 4.5?
Also, could the latest version of FSharp.Core be used with .net 3.5?
If you select .NET Framework 4 as the Target Framework in Visual Studio, the only F# version you can pick is F# 3.0:
If, on the other hand, you select .NET Framework 4.5, the option to pick F# 4.0 becomes available as well.
Based on that, it looks as though .NET 4.5 is the minimum version for F# 4. That's only Visual Studio's view, though, so it may be possible that you can use F# 4 with older versions of .NET using other development tools.
If you look at the NuGet page for FSharp.Core 4.0.0.1 (currently the most recent version), you'll see that it supports these frameworks:
.NET 2.0
.NET 4.0
.NET Portable Profile 7 (portable-net45+netcore45)
.NET Portable Profile 47 (portable-net45+sl5+netcore45)
.NET Portable Profile 78 (portable-net45+netcore45+wp8)
.NET Portable Profile 259 (portable-net45+netcore45+wpa81+wp8)
Like to know what are the step need to do for integrating MVC2 .net 3.5 to MVC3 .net 4.0 without using any upgrading tool.
The only thing this should require is a .NET framework upgrade on the box serving IIS. Any MVC2 .NET 3.5 app should work seamlessly side-by-side with an MVC3 .NET 4.0 app.
I have a solution with several Silverlight Class Libraries and a Silverlight Application in it. I was originally built in VS 2008 with Silverlight 3.0. What changes do I need to make so that it builds using Silverlight 4.0? I already have VS 2010 and the Silverlight 4.0 toolkit installed.
When I opened the project it seems to have upgraded to .NET 4.0 in my ASP.NET Web Project but not the Silverlight projects. Pretty sure they are still building against .NET 3.5 and Silverlight 3.0.
Thanks.
Since VS2010 supports Silverlight mutlitargeting as well as .NET multitargeting, you have the option in each Silverlight Project Page to upgrade the target type from Silverlight 3 to Silverlight 4.
