When I try to do it I get the error "The application requires .NET Framework 3.5 SP1." I have .NET 4.0, how do I install 3.5 SP1? Can I have both?
Feel free to install all versions of .Net. They will not interfere with each other!
For adding dependencies to your project I recommend NuGet. Really handy and makes the project clean by adding references into it instead of requiring additional installation packages.
.Net 4.0 projects are capable of using .Net 2.0, .Net 3.0 and .Net 3.5 libraries. But note that projects running under ".Net 4.0 Client Profile" can have problems doing this, and you only get a misleading error when attempting to run the project. From within Visual Studio everything seems right.
Just like Tedd Hansen says you can sure have as many .NET versions as you want in your computer for it creates no conflict at all. I take it you are just trying to install something. If that's the case then you can always use this link to download the bootstrapper that will determine the right 3.5 verison for you (x86 or x64) and download and install it.
If you are developing an application you can change the target framework of the project by going to the project properties page and, in the compile tab, click on the "Advanced Compile Options" button. There you'll be able to choose.
And, also as Tedd mentions, you should avoid targeting the "Client Profile" versions unless you specifically know that the subsets present therein are sufficient.
On my machine (Windows 7 Enterprise x86) I have installed .Net framework 4.0 and Enterprsie Library 5.0 without any problems. Maybe some other issue you're facing?
IAdapter,
I've answered this already. See my answer and the workaround in the comment dtd Feb 5, 2011.

I'm certain there's probably a bunch of things going on here that I don't understand well enough, so forgive me if this is a stupid question or if there's obvious details missing.
I have a Visual Studio 2015 solution that I've upgraded from .NET 4.5.1 to .NET 4.7.1. The solution consists of a website (not web app) project, and several libraries. The libraries don't really have any dependencies (except eachother) and while they are targeting .NET 4.7.1, they don't use, need, or reference .NETStandard.Library.
When I compile one of the libraries in particular, it keeps copying a bunch of .NET 4.7.1 facade dlls into the website bin folder. Unfortunately, the website is a Kentico 11 application, and it keeps trying to load the System.IO.Compression.ZipFile facade, and chokes on it because it's a reference assembly, not a real assembly.
If I delete the .dll, everything runs fine... but I don't want to delete it every time or add a post-build event to delete it. That's just silly.
Can anyone help me understand what's going on here, and how to clean it up?
Kentico 11 can only target up to .NET 4.7 so in an attempt to fully support your .NET 4.7.1 libraries I believe it is copying in those additional facade DLLs. This is based on the .NET 4.7.1 release announcement, specifically this section:
BCL – .NET Standard 2.0 Support
.NET Framework 4.7.1 has built-in support for .NET Standard 2.0. .NET Framework 4.7.1 adds about 200 missing APIs that were part of .NET Standard 2.0 but not actually implemented by .NET Framework 4.6.1, 4.6.2 or 4.7. You can refer to details on .NET Standard on .NET Standard Microsoft docs.
Applications that target .NET Framework 4.6.1 through 4.7 must deploy additional .NET Standard 2.0 support files in order to consume .NET Standard 2.0 libraries. This situation occurred because the .NET Standard 2.0 spec was finalized after .NET Framework 4.6.1 was released. .NET Framework 4.7.1 is the first .NET Framework release after .NET Standard 2.0, enabling us to provide comprehensive .NET Standard 2.0 support.

Update:
I was unable to reproduce your issue in Visual Studio 2017 Version 15.6.2.
I installed a Kentico 11 website project targeting .NET 4.7. I then created a library project that targeted .NET 4.7.1. I added some dummy code to the project to make use of Sysetem.IO.Compression and System.Net.Http namespaces. I added a reference to the project from Kentico and ran a build. No facade DLLs where copied to the bin folder.
This post indicates the issue was fixed in Visual Studio version 15.6 https://github.com/dotnet/sdk/issues/1647#issuecomment-364999962
The additional files that get deployed to your bin folder are needed to support referencing and running .NET Standard 1.x and .NET Standard 2.0 libraries in your .NET Framework application.
We have documented this as a known issues with .NET Framework 4.7.1.
The presence of those additional files is not sufficient however. You also need to have binding redirects generated in order to ensure types correctly unify across libraries.
Visual Studio 15.6.3 (and later) have a change that will automatically generate those binding redirects for your application.
.NET Framework 4.7.2 addresses the issues that require those additional files to be deployed with your application. When targeting or running on .NET Framework 4.7.2 you won't have any additional files copied to your bin folder and no binding redirects will be automatically generated.
You can try .NET Framework 4.7.2 and see what's new by following the instructions here.
References to assemblies have their own properties. You can specify there if you want to copy the assembly to the build output directory. Maybe somewhere it is set to true. To check that go to Solution Explorer in Visual Studio and right click on the referenced assembly. Then click Properties and look for property named "Copy Local".
Does anybody know how I can run Awesomium.NET on .NET 3.5? Seems to only work on 4.0-4.5.1 right now.
According to this question, Awesomium 1.7 should be compatible with 3.5 by adding Awesomium.Mono to the project instead, but it seems like I'm not able to do that. When choosing 3.5 project in Visual Studio the Awesomium.Mono just disappears from the references list.
Well when I started using Awesomium web browser at version 1.7.0 the reference dll are builded using .net 4.0 version. You should try to look for an older version like 1.6.6 or 1.6.5 and check if they are builded using a older .net version. If you target your project to .net 4.0 you should not have any problem because at least windows XP with service pack 3 should have installed .net framework 4.0. But windows XP support has ended.
A quick solution (but not the best) is to target the project to the .net 4.0 and export all dll references to the build path. That should make no problems when deploying the app to your clients machine because the exe will reference to the build path.
Could you give me the reasons of why you are targeting .net 3.5 so I can understand a little more your issue with .net versions and try to think about another solution for you?
I'm a student and at the moment i'm doing an internship at a company. This internship is about analysing a project. For this project I have made a demo to show to the Marketing director. The demo I have made is a simple project created in Visual Studio 2010 in c# with Windows Forms and a connection to an Access database.
So now i have to show this demo to this director in a presentation but after this presentation the director wants the project on his computer so he can try and use it. The problem is now that the computers here in this company don't have .NET framework 4.0 and the computers are so protected over here that we can't install anything new. To install something you have to go through a procedure that takes weeks.
I have looked al over the internet but all i find is how to install the .NET framework.
Is there any possible way that I can create an standalone exe without the need to install .NET framework? Please help!
If you want to execute an application that is developed using Net Framework 4, you will need to have installed .Net Framework 4 on client computer.
Your application is compiled in CIL (Common Intermediate Language), so it needs to be interpreted by the framework engine.
It is the same if you want to execute a Java program. You will have to install the Java Machine.
The only way you don't need to install frameworks is programming native applications with C, C++.
C# now supports this with .NET Native.
Instead of compiling to intermediate language, it will compile to native code and run with statically linked .NET libraries. Therefore, there will be no .Net Runtime requirements for end-users.

Only works for Windows 10
You can't build a C# executable without .NET Framework. Even if some resources indicate that you can, that only works in theory.
But you could use an older version of .NET Framework like .NET 4.0. If this doesn't work for you, you have to choose a language like C++ which doesn't require CLR at all.
Update 2018:
Do not target .NET 2.0 or 3.5. It's not compatible with the 4.x version. However, .NET 4.0 targeted binaries work with .NET Framework 4.0, 4.5, 4.6, 4.7 and so on. So to reach maximum compatibility, compile with .NET 4.0. You will have to accept that some features will not be available, however, your binary will run virtually anywhere.
(2018: By now, .NET 2.0 - 3.5 has much lower distribution than 4.x)
Delphi is your solution, deploy native bin executables
YES, THIS IS POSSIBLE!
At least 3 ways exist:
1.you can check all OSes that you planning to run your app and build with such version of .NET. As Windows have a built-in framework libs.
Vista -.NET v3.0 -- All service packs
Windows 7 - .NET v3.5 -- All versions and service packs
Windows 8 - .NET v4.0 [Best choice if you are not sure]
Windows 8.1 - .Net v4.5
Windows 10 - .Net v4.6
as they are already pre-installed by default -- no extra install will be needed.
2.For windows 10 you can compile it into native code (but not into CIL) with ".NET Native". This is means that there are no .Net Framework will be needed for apps.
3.There is Turbo Studio (earlier Spoon and earlier XenoCode) that can wrap everything that your app needs and runs it in as a standalone.
From their site:
Turbo Studio
Run .NET Without .NET. Easily embed runtime dependencies such as .NET, Java, and SQL directly into virtual applications. Launch reliably on any desktop, regardless of underlying component installs.
You can use Mono and statically link you program, so your program don't need .NET CLR runtime and act as standalone program.
Mono Project
In more modern versions of .NET such as 5 and 6 and even with releases of .NET Core it had become a supported scenario to produce what is referred to as a single-file executable as well as a self-contained application.
As I understand it, these technologies take place of and build upon some of the capabilities that had been in the Mono development stack for a while now. Typically I've seen this feature used for applications which would be deployed to servers such as web sites and microservices however it could be used for scenarios such as the one that the original poster illustrates.
Using the .NET SDK publishing (producing the executable) for a single-file executable can be done using a command as the one below which comes directly from the documentation.
dotnet publish -r win-x64 -p:PublishSingleFile=true --self-contained true
For more details see Single file deployment and executable in the Microsoft .NET documentation site.
To be honest, it really isnt a problem nowadays. the .NET framework is found on almost every single computer nowadays, and you can even make a installer with Advanced Installer that silently install the .NET framework on your computer when you are installing the programme.
My problem is that my C# .Net executable is running on machine which has Visual Studio 2010 installed, however it is not responding where only .Net 4.0 client profile is installed.
What could be the reason? I've tried with dependency walker but couldn't found anything.
While all of the other answers are correct, you might take a look on the "my project" page in your solution. There you can find (and eventually change) the used net versions. That is better than trying all net versions...
The client profile is a small and in most cases insufficient subset of the .NET runtime. Install the full .NET 4.0 runtime instead.
Try installing 4.5 Framework 3.5 and 3.0 frameworks also and see if it works.
http://www.microsoft.com/en-in/download/details.aspx?id=30653
That's because that VS2010 has and supports .NET Framework versions (2.0, 3.0, 3.5, 4.0). So try to instal all of them and also 4.5 Framework on that machine. Also, what you could do is to see on which Framework version have you made your project and you'll know which one you're machine is missing.
Try installing the "Microsoft Visual C++ 2010 Redistributable Package" on the machine where the executable is not working.
I am developing using 3.0 and VS 2008.
The problem is my build server does not have 3.5 installed and therefore I cant build the solution as MSBuild for 2.0 will not support the VS 2008 solution file.
There is no easy answer to this besides downgrading to VS 2005.
Any ideas folks?
VS2008 supports C# 3 - you may be using C# 3-specific features while still targeting .NET 2.0.
Is there a strong reason why you can't install .NET 3.5 on the build server? That would be my preferred solution, rather than regressing the version of VS you use.
You could probably automate downgrading the solution/project files - if you're not doing anything complicated, it'll just be a matter of changing version numbers - but it's not great to have the build server using a different compiler to the developers, IMO.
Since you have VS2008 projects and solutions you will need to install .NET 3.5 on you build server. Since you can still target .NET 3.0 or .NET 3.5 having .NET 3.5 installed on your build machine should not have any impact on the target environment.
Is it not possible to include the different versions without 'installing' them? In the repository can you add versioned .NET and point the build script to the version(I'm thinking like a submodule in Git) you want for that project? So instead of installing .NET 3.0, 3.5, 4.0, etc include the libraries?
