Microsoft Visual Studio not opening files
<p>Whenever I try opening a .cs file with Visual Studio, I get this error :</p>

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

<p>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. <a href="https://i.stack.imgur.com/w23aP.png" rel="nofollow noreferrer">Here is a picture</a>.</p>
