Can I Change The Target Framework Version In Express 2010
Aug 15, 2010
I am attempting to write a program in Visual Basic Express 2010 that uses .NET Framework version 3.5 instead of 4. (The computers that I plan to use this program on only have .NET 3.5 SP1, and are painfully slow, so I don't want to upgrade them to .NET 4.)I have seen in the documentation that the Express edition does not have the option to change the target framework in the "New Project" dialog. However, when I go to the Project Properties window, there is not a drop-down list for the target framework, either.Can I change the target framework version in Visual Basic Express 2010?

I created a VB Console app and it defaulted to .NET 4 but I need it to be .NET 3.5. I've been looking but all the references I find say to change it on the 'Compile' tab in properties but I don't have a compile tab or anything else that lets me change the target framework.
Note: I'm using VS2010 Ultimate

I upgraded a solution with multiple projects from VS2008 to VS2010.One of the projects, a class library project, won't compile, although there are no errors in the error list.On the References tab of the project properties, the above error is displayed: "Could not resolve mscorlib for target framework '.NETFramework, Version-v4.0'.This can happen if the target framework is not installed or if the framework moniker is incorrectly formatted." .NET framework 4 v4.0.30319 is installed, and so is v3.5.All other projects build and work fine.Not all workstations experience this - some workstations can open the same solution without this problem occurring.Computers which have this problem also have VS2008 installed, and the same project compiles without issue in VS2008 on the same machine which has the problem in VS2010.

Problem: A 2 year old solution made in VS2010 with vb .net 2.0. We are going to convert it on 4.0. So, the question is how? On a C# solution is quite simple since there is the compile tab where you can change the target framework, but here on vb net i can't find it.
Here it is what i see on project properties[URL]..

How come software created in an older framework version won't run on a newer framework version? Actually whenever i try to run some old specific software having .net 3.5 framework on my PC they show they needs .net framwork 1.1 . What a bad thing?My newer version of Photoshop ans Ms office open all lower version files.

I started a project in VB 2008 and the target Framework was obviously not 4, like it forces in VB 2010. The issue is the computers this application is being deployed to have 3.5 as the latest .NET Framework.

I've been working on a new application and realised that I want the target framework to be 3.5 (4.0 isn't rolled out yet). So, I changed it and now when I try and debug I get the following error:
"An error occurred creating the form. See Exception.InnerException for details. The error is: Unable to cast object of type 'System.Windows.Forms.SplitContainer' to type 'System.ComponentModel.ISupportInitialize'."
I really don't want to have to delete and recreate the splitContainer....

I have built a Dll and a Windows Service in vs2010. Both are targeting the .net 3.5 framework, but when I install it on the server it installs fine, but for some reason it targets the 2.0 framework and any time the methods fire that are using linq it crashes out with a clr20r3 error system.nullreferenceexception. Not really sure why it's not targeting .net 3.5.

I wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

I have an desktop application that references several dlls. All are targeted for .Net 3.5, x86. The applicaiton has been deployed for several years and was upgraded from visual studion 2008 to 2010 last year. I have made several changes to the app since then (as recently as last Thursday) with out any issues. Now, everything builds, but when I run the application, I get a type initialiazer error when one of the projects is loaded by the main application.
The error messsage is {"Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.":"System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}.
There were no changes to this project since the last successfuly deployment last week, but today I am getting this error.

Is there any way to downgrade the needed version of the framework for my program Currently I run it on my test computer and it asks me to download 4.1 version.

Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.

My VB.NET 2010 app currently targets .NET 3. I have to update it to target .NET 4 to get around some Locale / CultureInfo issues. What's the difference between .NET 4 Client Profile and the other .NET 4s I have on my machine: Extended and Multi-Targeting Pack? Which flavour of .NET 4 should I target? I want to target the flavour that the average user running Microsoft Office (Excel/Word/Outlook) out in the wild is most likely to already have. Why (on my machine) is there only a regasm.exe for v2.0.50727 and v4.0.30319? Why not a separate version for the other versions installed on my machine? (3, 3.5)

Does the Express Version support adding multiple soultions (.sln) to a project or is this only available with the Professional version.I see that I can add a DLL as a reference that was built in 2010, but it is not letting me step into it with the debugger (or recompile changes to its source).

Is there any way (via code or otherwise) that you can tell what version of the .NET framework a particular EXE or DLL is targetting? I know the long way round would be to try and run it on a machine with just .NET 1.1 on, then if that doesnt work try it on a machine with 2.0 on, etc etc

I developed an app using the .net framework 3.5 sp1. I have now been told that the published version must not require sp1 but just the 3.5 framework.
So I uninstalled sp1 from my pc but not cannot publish the app. The app code will run without error but when I build it for publishing I get the error The "RequiresFramework35SP1Assembly" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:WINDOWSMicrosoft.NETFrameworkv3.5" directory.

Simple question that does not seem to be covered: If I use a lot of Debug.WriteLine statements in my code, will they be completely absent in my production version?
I mean: Is the compiler smart enough to not emit any code for those calls? Or would I have to surround them by #if DEBUG..#end if directives?

I am writing my first application in VB 2008 Express with .NET Framework versions 2.0, 3.0 and 3.5 installed. When completed, I assume the application will need to check whether it is running under .NET Framework version 3.5 or later. I have not found any properties that I could get which would give me this information about the environment in which the application is running. Is this something that the non-user code in which my application is wrapped by the IDE checks, or is it something that I have to check myself within the application ? If the latter, how would I do that ?
