I get the following error when trying to build/run my application:
Error 30 – Unexpected error writing metadata to file ” — ‘Not enough storage is available to complete this operation. ‘
I have tried the ‘/3GB boot.ini’ solution but it caused even more problems to my computer.
You can delete .suo (situated in the same folder with .sln file). Of course, you will lose some information about solution like last opened files etc, but this may help for some time until this file grows again.
Also, in my case trying to avoid to open a lot of files in VS at the same time, exceptionally windows forms was helpful.
Both of this steps help to make an error happen not so often but don’t fix an issue itself.
