Problems making design changes if no operational internet connection; documentation does not note requirement for internet connection.

[selebi-pikwe]

If there is no current internet connection:-

• the designer does not load the model fully/correctly (no properties page is displayed for the model);
• entities cannot be added; entity properties cannot be changed ('The given key was not present in the dictionary' error);
• produces build error (see below).

Strangely, Enum addition/changing seems to work.

When the internet connection is restored, everything works fine again (but only after reloading VS, reloading the solution/projects and the EF model).

VS2022 17.8.7, EFDesigner 4.2.7.3, no changes to .tt files.

Build Error:
