You have a few options: To get it programmatically, from managed code, use Assembly.ImageRuntimeVersion:

<pre><code>Dim a As Assembly = Reflection.Assembly.ReflectionOnlyLoadFrom("C:\path\assembly.dll")
Dim s As String = a.ImageRuntimeVersion
</code></pre>

From the command line, starting in v2.0, ildasm.exe will show it if you double-click on "MANIFEST" and look for "Metadata version". <a href="http://blogs.msdn.com/b/suzcook/archive/2003/06/20/57191.aspx" rel="noreferrer">Determining an Image’s CLR Version</a>

Yet another option via Visual Studio, add a reference to the DLL to any project, then right-clicking on the new reference and click Properties, you can see what you are looking for in Runtime version:

Expanding on the answers here, this can blow up if there is a dependent assembly. If you're lucky and you know where the dependent is (or even luckier, it's in the GAC) then this may help ...

<pre class="lang-cs prettyprint-override"><code>using System.Reflection;
using System.Runtime.Versioning;
// ...
{
 AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(CurrentDomain_ReflectionOnlyAssemblyResolve);
 var asm = System.Reflection.Assembly.LoadFrom(@"C:\Codez\My.dll");
 var targetFrameAttribute = asm.GetCustomAttributes(true).OfType&lt;TargetFrameworkAttribute&gt;().FirstOrDefault();
 targetFrameAttribute.Dump();
}

Assembly CurrentDomain_ReflectionOnlyAssemblyResolve(object sender, ResolveEventArgs args)
{
 var name = args.Name;

 if (name.StartsWith("Depends"))
 return System.Reflection.Assembly.ReflectionOnlyLoadFrom(@"C:\Codez\Depends.dll");

 return System.Reflection.Assembly.ReflectionOnlyLoad(args.Name);
}
</code></pre>

I have an old dll that was compiled against the .NET framework and deployed. I am not sure which version of the .NET framework it was compiled against. I am wondering how I can determine which version of the .NET framework this dll was compiled against? I cannot trust the source code because I believe it has been upgraded to Visual Studio 2008 and changed to .NET framework version 3.5.

Determine .NET Framework version for dll

Visual Studio

我有一个旧的dll，它是针对.NET框架编译并部署的。我不确定它是在哪个版本的.NET框架上编译的。我想知道如何确定这个动态链接库是在哪个版本的.NET框架上编译的？我不能相信源代码，因为我相信它已经升级到Visual Studio2008并更改到.NET框架版本3.5。
