Way To Determine Through Code What Is Latest Version Of .net Framework Pc Is Running

Feb 3, 2009

I have developed a small application in VB.NET 2008. It uses .net framework 3.5. But somehow it also runs in computers with .net framework 2 or 2.5. Is there a way to determine thru code what is the latest version of .net framework the pc is running. This way I can give a warning message box that the required framework is not installed.

IDE :: Why System.dll Is Not Referencing The Latest .Net Framework Version

Apr 25, 2010

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?

Version Of The Framework Running Under ?

Apr 22, 2010

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 ?

IDE :: Auto-Referencing Latest Version Of Assembly

Feb 23, 2009

We have one program that acts as a "server" (so to speak) and many programs that reference it. every time we update the server, we are forced to update all the dependent programs to reference the new version number. Our IPC communication protocol is pretty stable and doesn't change, so we aren't worried about upgrade incompatibilities. I would like to know how to automatically reference the "latest" version of an assembly. What I mean is, if I choose Project->properties->references, I always get a specific version. Is there a way to reference whatever the latest version is? This way, we wouldn't have to update every program that is dependent on our server every single time there is an update.

Need To Load Latest Version Of Specific Assembly

Nov 10, 2010

I have this situation where LoadWithPartialName appears to be the only good alternative, although it is marked as Obsolete. I work in a very tight dev environment with versioning and deployment policies that cannot be easily changed or bypassed. Let's say there's a .NET executable that I have no control on (from another division). Let's call this the client AppA application. AppA's version is 10.11.12.x. Application AppA has a direct reference to one of our class library that provides some service to the caller (returns some information).

Let's call it SvcB and the version is also 10.11.12.x. Now, AppA's division does not need to update their system as often as we do, so AppA's version will stay 10.11.12.x for some time, probably until we decide to change the format of the class that is exchanged between us. Our division needs to change the logic behind the service SvcB more often and the version must change with every major deployement.

So let's say we change the logic and we deploy a new version of SvcB, 11.02.11.x. AppA will still reference the old version, so the logic being used is now incorrect. We are thinking of creating a new "facade" to our service. Let's call it SvcFrontB. SvcFrontB's version will stay the same, in sync with the AppA's own version. Now I need SvcFrontB to load the most recent version of SvcB through reflection. This way, I am sure the latest logic is always used. How do I achieve that without using LoadWithPartialName ?

VS 2008 - Detecting .NET Framework Version

Jan 13, 2010

I 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).

Can I Change The Target Framework Version In Express 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?

Could Not Resolve Mscorlib For Target Framework '.NETFramework Version-v4.0'
