I am creating a program in VS 2010 which obviously uses Framework 4.1 However now that I am trying to test the program I am realizing usually only developers like us have this version.. 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.

i know we can detect the framework installed on a system, but here i have a dot net component, and want to find out which framework is needed for it to run?
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.
View 6 RepliesI 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?
View 11 RepliesI 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?

View 3 RepliesI write programs in VB 2010 which uses .Net Framework 4.0. However my school currently only has .Net Framework 3.1 (3.something, think its 1)Is there anyway i can "downgrade" the needed .net framework, or even just select another .net version to use?
View 1 RepliesHow can I tell what the size of my program is and how much disk space is needed to install. When I publish the program and install it on another machine it will show up in the control panel but does not show what size the program is?Also when I publish updates with it says something like installing 10mb. Is this an additional 10 mb everytime, I guess not, but can someone explain what it all means?
View 10 RepliesI'm creating an updater for an IP address, and I need to ensure that only one instance is running on the computer. This is to prevent (or at least make it more difficult for) having multiple tunnels running (it's an updater for an IPv6 tunnel).I've seen various ways of doing it in VB 6.0 and early .NET, but nothing that deals with .NET 3.5 or VIsual Basic 2010.

View 4 RepliesI 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 ?

When I distribute my program to another, I don't know which .net framework he has loaded. My program was developed and compiled with VS 2005 and I am using .net 2.0. Will my program work on his machine if all he has loaded is .net 3.5? (or something else)

View 8 RepliesI need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I'm writing a code that will check if .net framework 3.5 SP1 is installed before installing the program.The command I found googling around was System.Runtime.InteropServices.Runtime Environment.GetSystemVersion..I wasn't able to verify the correct .net framework version using this command.I'm currently running 3.5 SP1 and this command is showing v2.0.Is there another way to get the correct .net framework version?
View 2 RepliesIs it possible to reduce the version of .net framework of my application. For example: Host using my application have .NET 2.0 I make changes in my app so that it always run as .NET 2.0 not the latest .NET 3.5
Or another idea i have is to deploy .NET 3.5 in installation package i.e. if he runs my app and it detects .NET version and if its not .NET 3.5 then .NET 3.5 installer should open else my app should run.
Mainly I ask this because I don't want to distribute both versions, and if I need to instal a 64bit .NET on an x64 PC and a 32bit .NET on a 32 bit PC then I would need to make this check in my loader application to download the correct version for the correct PC.

View 2 Repliesconfirm the forum for this question about Visual Web Developer 2010 Express. I found a VWD Express forum, but it was in Spanish... Lo Siento. My issue is selecting a down-level, 3.5, framework version as I create a new project/website. I have figured out how to CHANGE the target framework version once the website/project is created. I have the 3.5x installed on the system and available. The articles I have seen discussing this issue, refer to a framework version selection drop list in the new project creation dialog/wizard. I do not have that option.

I have a VS2010 solution (upgraded) that has two projects, an EXE and a DLL. In both the Target framework versions are 4.0. When one look at the references of the EXE project, one can see that the System.dll (and System.Core.dll and so for) references to the v4 version (the latest); however, in the DLL project the references points to the .Net Framework v2 version. Why is this happening? How can I make all my projects to point to the v4 libraries?

View 1 RepliesHow do I tell what version of the dotnet framework is required by my application?I am using Visual Studio 2008.I have these installed on my machine:
.NET FW 2.0 SP 2
.NET FW 3.0 SP 2
.NET FW 3.5 SP 1
Are the service pack 2 updates inclusive of service pack 1? I don't think I need .Net 2.0 - do I need 3.0 if I also have 3.5 ? Do I look somewhere inside Visual Studio, or at my references?
Is it possible to load a referenced assembly only if the .NET Framework version is lesser than a specific number? I'm using a selfmade LINQ library on .NET 2.0, but if the framework is 3.5+, it should use the M$ LINQ library, and ignore the selfmade one.

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.
