I was able to resolve this issue by adding longpaths = true to my config. prior to that I had enabled long paths in windows via the registry.

[paul1956]

@elachlan can you be more explicit as to what config file the line needs to be added to.

[elachlan]

Your local git config.

Also you need to enable longpaths in windows:

[paul1956]

@elachlan did all those things and it still didn't work completely. Git works, merge works but Visual Studio Community can't read MissingPropertySerializationConfigurationAnalyzerTest.vb. I moved repo directory to C:\Repo, deleted artifacts directory and then everything worked. Thanks, this should be documented if it's not possible to shorten path length.

Verified this on latest winforms repo, the long path issue is fixed.
