问题
I have a Visual Studio 2012 solution /Foobar.sln. It contains one Class Library project and one Unit Test project. A few days ago I noticed a new file /Foobar.sln.ide/graph/Foobar.sln.ide.
Contents:
<Solution Format="0.0.0.3">
<Version>0001-01-01T00:00:00Z</Version>
</Solution>
I'm not sure what I was doing when it was created, since I didn't notice it until a few days after it was created.
Today, several days later than I first asked this question, it appeared again in an Excel VSTO Add-in project. My guess now is that it's related to closing the solution, since it appeared in between the time I committed my changes and the time I opened a new project (not a VS project, just a file being edited). I haven't reproduced it.
What created this file? What does it do? Is it safe to delete? Should it be checked in to source control?
回答1:
Are you using the "Roslyn" compiler. If so, this creates the .sln.ide folder in your solution folder. I believe it's to do with complier caching.
