C# Which .net version does my app require - c#

Sorry if its a stupid question. But I just wrote a tiny c# application and want to know which exact version of .net does my application requires .
Is there a way of knowing this , other than to uninstall and reinstalling all the .net versions on my PC.
my app btw is : http://www.ziddu.com/download/11874881/PerfectUpload.exe.html ( 14kb)
Thanks

In the VS IDE, right click on yourProjectName-->Properties-->Application-->Target Framework, and you will most likely see the framework version 3.5.

This application requires .NET 3.5 to run as it references System.Xml.Linq assembly and more specifically the XDocument class in the PostToImgur method.

You can specify the required .NET version in the project settings!

Can I use MONO to create a program that runs without the .NET framework being installed?

I need to write something for a Windows XP embedded computer, which does not have .NET installed.
I already have written the program in .NET, so I'm wondering if there's a way to make it run without .NET?
Perhaps using MONO to create some all-in-one .exe?
Thanks for any thoughts / ideas!
Take a look at mkbundle from Mono:
The resulting executable is self contained and does not need the Mono
runtime installed to run.
When running managed code - .NET/Mono assemblies, a framework is required to be installed. Depending on your dependencies, you may be able to run under mono without modification. Mono is compatible with Windows XP. Parts of .NET are not compatible with Mono such as WPF.
Firstly make it run without .NET is an error concept. .net program must run at .net Environment. You can say without .netframework.
If you want to use .netframework, may these can help you:

Or you can setup monoruntime on this os

easiest way to convert .NET project from 4.5 to 4.0?

I have a .NET application that I built in 4.5, which has references to a bunch of libraries that were built in 4.5, which themselves have references to 4.5, etc. A user group that I'm trying to distribute the application to is having problems running the executable because they have 4.0 installed; in particular, they're getting a MissingMethodException:
Method not found: 'System.Type System.Runtime.InteropServices.Marshal.GetTypeFromCLSID(System.Guid)'.
Because we may have trouble getting each user upgraded to 4.5 (as none of them have admin permissions on their machines and this would require a separate upgrade request for each user), I'm looking at finding an easy way to rebuild the project as 4.0. This seems to require that I rebuild every library and its referenced libraries in 4.0; is there an easier way to do this than going through each library one by one and building a 4.0 version? I'm thinking maybe like a one-click option for "Rebuild all referenced libraries in target framework" or something like that.
If you have dependencies on .Net 4.5 DLLs then you will need to also get .Net 4.0 versions of those if you want to successfully downgrade your project. A .Net project can only reference .Net DLLs up to the same version of .Net as the referencing assembly.
The easiest way to do this is to use something like NuGet to manage your dependencies. Note that when you change the target framework version of your project in VS you will need to uninstall and re-install dependencies with NuGet as NuGet does not automatically do this for you when you change the target framework version.
Of course if all the dependencies are to your own code and you aren't publishing this through a dependency management system like NuGet you will need to downgrade all your other code to .Net 4.0 as well
When I use Visual Studio, I right click on the project, change the framework, fix the References and recompile. Usually straight forward.
Please, have a look at this MSDN page to correctly switch your project to a lower target framework without problems! It is a little bit outdated for what concerns versions, but the process is the same described!
This is based on my experience. I had an application initially created in .net framework 4.5 but I wanted to convert it in .net framework 4.0. I created new project initially created 4.0 and then I did copy and paste of all the forms and controls of my previous application and it works. Framework 4.5 is using Aero2 and 4.0 is Aero... Good Luck :)

Add-in project must be .NET 3.5 rest of the codebase is .NET 4.0 how to solve?

I wrote an add-in for Inventor 2012, the add-in must be .NET 3.5 it seems. I have not found an update that enables .NET 4 yet.
The rest of my codebase is .NET 4.0 and hence I cannot reference my other projects from my add-in code. Is there a workaround for this?
No. You could spawn a separate process and talk to it, but other than that, outta luck.
It looks like Inventor 2013 is compiled for .Net 4. That is not a patch I can easily apply at the moment.

How to create .NET2 compatible app in VS2010?

I'm using Microsoft Visual Studio 2010 and .NET4, but I would like to create application(Windows Form Application) that can be also run in .NET2. The reason is that I want it to be very easy to use and portable across many machines and not everybody has .NET4 installed.
Can I do it or do I need to install older version of Visual Studio? Is so what version is the best for most portable .NET app.
You can modify the target framework in the properties of the project:
You can select which .NET Framework version you want to target when you create a new project. If you want to change the framework of an existing project, do what Darin has illustrated.
Just modify the target framework by looking at the propeties of the solution you are working on.
I would highly advise you to target .NET 3.5 just based on the age of .NET 2.0.
.NET Framework 2.0 was attached to Visual Studio 2005.
By modifying the target framework is the way, but if you are thinking of portable maybe what you need is some kind of native code that works in every and/or most windows version.
Don't forget to delete redundant namespaces from your namespace list. For example LINQ...

deploy application without the .NET

I have to give my customer my application. It's a simple application(3Mo).
I think it's really unnecessary to oblige my client to install the whole .NET framework (the 3.5) to work with a simple application (3 mo). I mean I'm sure that there is a way to avoid that, just include some dlls or something like that.
Well I have the dll in my project reference(LINQ dll, core Dll, system Dll, winfom Dll, office Dll and some other)
is it possible to give the application with those dll and that way I avoid installing the whole .NET framework?
Well I don't even need to make an MSI or setup project,
just give him the exe generated with Visual Studio and that's it.
I'm using VS 2010, C#, 3.5.NET
It's worth noting that Windows comes with various flavours of .Net installed depending on the version of Windows. If I remember correctly...
Win7 comes with .NET 3.5 SP1
Vista comes with .NET 3.5
XP SP2 includes .NET 2
Depending on your target audience you might find that this is good enough!
If these conditions are true:
a) you really want to avoid .NET framework dependency
b) it's a really easy/small application
Consider the option of porting it to c++
If not
use default framework (.NET 2, or 3.5 or 3.5SP1) that comes by default in windows as Dan Puzey said.
No it is not possible. Client has to install .NET Framework 3.5 (with SP1) redistributable package.
Edit: If you didn't want client dependency on .NET Framework you should choose another application type: Web application where .NET dependency is only on the server.
Most people have some flavor of .NET installed although most don't yet have 3.5. But you can create an installer that will download an install transparently to the user. Also if you target the Client Profile this dependency will be smaller.
Your client should have .net, there's no reason not to and if they haven't, they are a fool. Running XP with less than Service Pack 2 is dangerous. For the non-technically-inclined, compare it to using a van that's been subject to a manufacturer's recall. It may not necessarily be faulty, but the manufacturer has told you that it's no longer fit for use and are willing to make good at their own expense. As a responsible business owner, you wouldn't shirk that responsibility. In a similar vein, maintaining your Windows installation to the manufacturer's recommendation is not optional.
Have you considered making it a web app, with asp.net? The effort of porting should be less than a complete rewrite (depends on the applications functionality).
