Why does Visual studio take so long to delete a file from the solution tree? The app freezes and sits there for what feels like an eternity.
If I delete the file from the file system first, then delete it in the solution it happens instantly.
Is there an option I can set somewhere to avoid this?
I've found that this is sometimes a symptom of project size. Deleting a file from a project with hundreds of files can take 30 seconds on my (admittedly slow) work computer. But deleting one of two files in a project is usually instant.
Do you have a version control plugin with Visual Studio? It may be contacting a server to make sure you can check it out...
If not, where is the file located? Is it a local file or on the network? Sometimes if on the network, VS has to check if you have windows access to delete the file.
Do you have Resharper installed? Once I installed it, it definitely slowed down file operations on my machine. Worth the tradeoff, I think.
it could be rebuilding/removing from the intellisense database or checking the rest of the project for validity once the file is deleted. Or it could just be that the new VSs are buggy.
It may be normal if your project size is very big. We are talking about a 50-200 projects solution.
If you have R# installed on your PC try to disable it or try to delete your project items with an empty recycle bin.
Altough I do not recommend it, you can try to delete all the *.opt and *.ncb files from all your project directories and bring Visual Studio up again.
