How do I know what version of the .net framework I need to build for

I have a bunch of solutions in C# that I've been handed. There is production code on the server, and I have a version of it on a local dev machine. I make a code change, and build the dlls. When I try to copy the dlls to the server, it gives me errors like:

"Could not load file or assembly 'myfile.dll' or one of its dependencies. 
This assembly is built by a runtime newer than the currently loaded runtime 
and cannot be loaded."

One of the issues is that the projects that I use for building ORM, data, and business logic are not on the server, but are on my local, and I can use them to build dlls, but it isn't helpful when I can't tell what the server is using either. Where do you find out what versions it runs and how to build to match? I know this is my own ignorance in not knowing how the .net framework works, the different versions, how to build for the right one (32-bit vs 64-bit a concern too?) and get things to work. I have looked around a bit, but no where seems to explain this.

To change the target framework of your project in vs2k10: Open project properties -> Application tab -> Target framework(its combobox with available versions)

To check/change the framework version on your server(it is for IIS 7.0 version):

  1. Open IIS manager.
  2. Click the “Application Pools” node.
  3. Find the corresponding application pool that your web site/virtual directory use(by default there is a “DefaultAppPool” application pool).
  4. Right click the application pool, and then select “Advanced Settings”
  5. There should be “.NET Framework Version”

32 or 64 bits should not bother you. To find the framework version, you must look for the website or virtual directory at IIS.

I don't have a Windows Server here, but it's something like this:

  1. Open IIS Management tool
  2. Find your website or virtual directory, right click and go to properties
  3. There should be a tab named .Net (or something like it)
  4. At this tab, there is a combo with the available runtime versions binded to IIS. The current is the one you're using.

These steps are for IIS 6. For IIS 7 it's mostly the same, but they don't call it "properties" window, it's "Advanced something".

I'm sorry for not having the proper details, but you'll be able to find it.
