Does NT7 support .NET 4 ?

hi,
Does NT7 support .NET Framework 4 ?

thanks

NT7 requires the .NET 3.5 framework, but works with 4.0 a well as this would just encompass 3.5 as well.

I currently have a DLL compiled in .NET 3.5 that is working fine with Strategies in NT7.

Had it re-compiled in NET 4. Copied over to NT custom directory,
I can compiled my old NT strategies fine.
But when i try to load it under strategies tab, it does not appear on the list box.
NT log tab complains.... "no default constructor blah blah".
Checking NT log file, it does not show the DLL as a loaded vendor assembly.

My query is why does a .NET 4 DLL compiled without errors in the first place ?.. But subsequently cannot load ?
I tried, repairing database, removing cache and tmp directories and all that, couldn't get it to work.

Recompiled the DLL to .NET 3.5 everything is working fine again.

So my conclusion, there are some issues NT7 needs to sort out before we can say it works with .NET 4

Please get your programmers to try it out.

thanks

aljafp,

First thought is, did you add back the reference to the DLL while removing the old reference?

I even remove everything... that is all libraries, all references and started from fresh.
But it did NOT work.

Just drop the .NET 3.5 library back and everything was fine.

Did your programmers actually tried NT7 with any .NET 4 compiled libraries ?

It is my understanding that NT7 does NOT support .NET 4.
NT7 is a .NET 3.5 application.
NT7 can however live concurrently with other .NET 4 applications

I hope NT can clarify. Because this was what Bertrand previously wrote

Perhaps its better to say you can't use a 4.0 assembly in a 3.5 program? You can have 4.0 on your computer (I do. Anyone with VS2010 does) but anything you compile for use within NT should be 3.5. Easy.

.NET 4 uses CLR 4 while 3.5 would work still with 2.0 - NT7 works on .NET 3.5 and 4, but is a 3.5 application.

I think what this might mean is that if your system has an .NET 4 installation, you can still run dlls created with .NET3.5.

However, when you are creating new DLLs you should use .NET3.5 and not compile to .NET4.0.

Installing NT7 w/ .NET 4

I have a new Vista install w/ .NET 4. When I try to download NT7 and install, it says it requires .NET 3.5

Is there a work-around so I don't have to run both .NET 3.5 & 4.0?

Hi thuff,

You will need to install .net version 3.5 for use with NinjaTrader.
