Upgrade R# to 2021.3

[robertcoltheart]

Sigh another set of wonderful breaking changes from the geniuses at JB.

Using VS2022 17.0.2 with R# 2022.3 windows 10

We do have "some" Behavior tests so don't want to migrate them yet.

Note, if you comment out //Behaves_like it appears to work.

Do you have a migration plan for Behavior?

Will take a look.

Behaviors will be supported for the time being, probably beyond v2. For v3 I'm planning on introducing Examples which will (possibly) deprecate behaviors, see machine/machine.specifications#141

Hi,

Any news on this? Thanks

[robertcoltheart]

Unfortunately it isn't a simple fix, I have a branch in progress but need more time to finish it.

[mikeblakeuk]

OK. Thank you for looking. It is blocking our vs2022 / rider upgrade.

Tracked here machine/machine.specifications#459
