All the nifty stuff in the IDE designer only works with net48 included in the target frameworks.

Additional background info: #684

All the nifty stuff in the IDE designer only works with net48 included in the target frameworks.

Tried it, now getting the following error " Could not resolve mscorlib for target framework '.NETFramework,Version=v4.8.1'. This can happen if the target framework is not installed or if the framework moniker is incorrectly formatted. "

@MattH-Work

A simple program sample please ? Forgot that it was already included...

Hi @MattH-Work,

First: Your .vbproj file which should (and possibly already does) contain:

<TargetFrameworks>net48;net8.0-windows</TargetFrameworks>

Second: You are missing an assembly reference in the project, to mscorlib.

And then enter mscorlib in the search box and check it:

Worked like a charm

I had originally just added ' net48 ' to the existing' TargetFramework>net48;net8.0-windows</TargetFramework '

I hadn't registered that the two TargetFramework references are now plural TargetFrameworks>net48;net8.0-windows</TargetFrameworks

Secondily, I tried adding a reference to mscorlib but the ' Add > Assembly Reference ' was missing, hence not being able to self fix the issue I needed to remove my existing form ( blank form, part of my template, not an issue ), add the reference to mscorlib then add a new form back in

Cheers
