Cannot find or open the PDB file -Net 4.8 - Application is in Break Mode

[giogio1]

I am trying to attach VisualStudio to NT8 and I can't while I have no problems connecting it to NT7.

I have VisualStudio 2017 and NT8 latest version 8.0.26.0 64-bit
This is what I observe:

-When I start visual studio from the NinjaScript editor I get the following message on VS:
the C# NinjaTrader.Custom is targeting .NetFramework, Version= v4.8 which is not installed in this machine.

But it is! I have the version 4.8.04084

It asks me to download it but I did not approve since I have it. I can also answer to Target 4.6.1 but How can I change it back ? Is it safe to do so?

- If I attach NT8 starting from VS I get in the VS output ending with the following lines:

'NinjaTrader.exe' (CLR v4.0.30319: NinjaTrader.exe): Loaded 'Microsoft.GeneratedCode'.

What should I do ?

Hello giogio1,

NT8 uses .net 4.8, you would need to allow VS to install 4.8 to be able to use it. The warning is coming up because the dependency is not met, the version you have installed separately is not the version that NinjaTrader is requesting. The next step would be to allow visual studio to fix the dependency by using the message it presents.
