Another CsScript dll issue
Hi -

I'm having trouble loading a C# script that uses a .NET v4.0 or v4.5 dll. Is there a way to make this load?

I've just taken the working code from a previous post and added a
Copy      Help
using System.Threading.Tasks;
statement. This example doesn't need it but a more complex one does - and this throws the same error as my more complicated one.

If I use the first x.SetOptions() statement I get:
Copy      Help
Error (RT) in CSTest:  0x80131600,
    (0,0): error CS1703: An assembly with the same identity 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' has already been imported. Try removing one of the duplicate references.    ?
If I use the second x.SetOptions() statement I get:
Copy      Help
Error (RT) in CSTest:  0x80131600,
    CSTest(29,24): error CS0234: The type or namespace name 'Tasks' does not exist in the namespace 'System.Threading' (are you missing an assembly reference?).    ?

System.Threading is described here - it uses the mscorlib.dll.

My guess (and it's only a guess) is that System.Threading was introduced in .NET 4.0 and an earlier version of mscorlib.dll is already loaded?

public class Test
public List<string> k { get; private set;}
public ArrayList a { get; private set;}
public Test2Strings[] testStrings {get; set;}

public Test()
k=new List<string>(); k.Add("string in List");
a=new ArrayList(); a.Add("string in ArrayList");
testStrings = new Test2Strings[3];
for (int i=0;i<testStrings.Length; i++){
,testStrings[i] = new Test2Strings();
,testStrings[i].aString = "First String " + i;
,testStrings[i].bString = "Second String " + i;

public string[] GetListAsArray() { return k.ToArray(); }

QM cannot use .NET v4.0 or v4.5 dlls.
QM uses .NET v3.5. Because it is always installed on Windows 7 and can be installed on Windows XP. Possibly in the future will be added option to use v4.5 instead.
Hi -
I just ran into the same issue with another DLL from another vendor. I found an older DLL from the vendor that works fine with .NET 3.5 today but they are adding new features in a month or two that I would like to take advantage of. I can ask them to compile for a 3.5 target (and they might) but it would be great if .NET 4.5 support was added to QM.
