Newbie - VS throwing errors

Hi all. New MC.NET user with another (probably) stupid question. Since I already had Visual Studio up and running on my PC, it was no problem getting the MC IDE to open Visual Studio. But: saving even simple changes is broken on my environment. See the attachments using a standard "new indicator" as a test.

I can navigate to the indicator just fine in VS and it opens. Great. I make an edit and save it - the file in the IDE goes blank! I get the following error in VS:
How do I fix this, what is the troubleshooting?

Ok, just realized something: the PLE IDE is automatically opening VS Code instead of my Visual Studio Community edition.

How to I redirect the IDE to open the right VS application?

Hello,

For correct operation VS should be launched from the PowerLanguage .NET Editor using the Launch VS button.

And for Visual Studio to be launched by default instead of VS Code, right-click any .sln file → Open with → Choose another app → select Visual Studio and check the 'Always use this app to open .sln files' box.

Thanks Kate, when I do that, I get a dialog notifying me that I will need the .net 4.0 framework. On Microsofts site, there is no 4.0 framework, so which should I download?

Version Developer Pack Runtime Release notes End of support
.NET Framework 4.8.1 Developer Pack Runtime Release notes
.NET Framework 4.8 Developer Pack Runtime Release notes
.NET Framework 4.7.2 Developer Pack Runtime Release notes
.NET Framework 4.7.1 Developer Pack Runtime Release notes
.NET Framework 4.7 Developer Pack Runtime Release notes
.NET Framework 4.6.2 Developer Pack Runtime Release notes
.NET Framework 3.5 SP1 Runtime Release notes January 9, 2029

After doing some research the best option seems to be downgrading to Visual Studio 2019 so there is support for .NET 4.0. Now it seems to work.

The framework is very old. When will MultiCharts be upgrading the .NET framework?

There's no ETA yet, but it's on our roadmap.

you don't need a Visual studio downgrade. I also use Visual Studio 2022. When I open it, a warning message should appear: select update the target framework to .net Framework 4.8 (recommended). If necessary, download the latest framework beforehand using the Visualstudio installer. In any case, I haven't had any problems so far

4.8? So 4.8 works for you.... it gave me headaches to no end. Framework 4.0 is the latest for MultiCharts, no?

yes multicharts.net should be based on the 4.0 Netframework. In principle, an update shouldn't be too much of a problem for the Multicharts.net developers, as you can simply specify a different target framework. However, you also want to be able to guarantee that the software runs smoothly and with the regular updates, it may not be easy to carry out all the necessary tests for each new update
