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
View 3 RepliesMy 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)

View 9 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 2 RepliesI 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.

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.

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

View 3 RepliesI'm using the x86 target CPU setting (and .NET 2.0 as target framework if that's important) for all of my projects and components. This worked without any problems with Visual Studio 2008. My developer PC uses a x64 version of Windows 7.But now I have a new project in Visual Studio 2010 where both, the main project as well as the user control component is set to x86 target CPU, but I still get following error when I try to run my main project with the user control placed on the form:
"Could not load file or assembly 'XXX' or one of its dependencies. An attempt was made to load a program with an incorrect format."
This is the normal message e. g. if the main project has a target CPU of "Any CPU" and the component only "x86", but in Visual Studio 2008 it worked fine if I set both to "x86". Why this is not working in Visual Studio 2010 anymore or what I need to change that it works again?
