Microsoft Visual Studio无法打开文件

Question

Whenever I try opening a .cs file with Visual Studio, I get this error :

Expected 1 export(s) with contract name "Microsoft.VisualStudio.Utilities.IContentTypeRegistryService" but found 0 after applying applicable constraints.

Visual Studio had been working working fine for me, then all of a sudden this started happening. I tried deleting the cache and even uninstalling the program altogether, but the error persists. I checked online everywhere, but nobody seems to have had this issue before. Here is a picture .

Answer 1

The best SO link I've found gives heaps of different options - see here - I would suggest running a repair on the install and try things other than clearing the cache.

The referenced link indicates a bunch of different conditions that affect how you resolve the issue. For example are you running express/community edition or professional etc?

Without knowing what causes the cache to get corrupted I can't answer exactly how to fix it.
