Forge does not create working projects under Linux

[CarstenKoenig]

When working in Linux I get lot's of "Input string was not in a correct format" when working with forge.

You can reproduce with:

forge new project -t console -n ForgeTest --folder ForgeTest

this outputs on my machine:

Forge should be run from solution/repository root. Please ensure you don't run it from folder containing other solutions

Do You want to continue? [Y/n]

Expected Behavior

Current Behavior

get the same kind of errors when doing a ./build.sh

maybe this is an deeper issue as I cannot rebuild Forge anymore on my system as well - there I get a MethodNotSupported Exception with FAKE:

Error: System.NotSupportedException: Type 'FSI_0005.Build' was not completed.

so I guess I better open an issue with FAKE

after some discussion on the FAKE issue and a manual paket update the errors are now as listed in the attached file:
