❔ Jetbrains Rider cant resolve any symbols

I tabbed out of Rider for 10mins to watch some youtube video, i tab back into rider and see this

its even showing void and uint and things like that as Cant resolve symbol, but dotnet run works without any errors

Restart Rider?

did that like 5 times

switched projects

changed msbuild version

restarted rider multiple times

create a new project and move all my code to that new project

nothing worked

I'm going to say you're making this actively worse, because it's probably something you've done

like i said in the post: i tabbed out of rider to watch a 10min youtube video, tabbed back in and found.... that

File -> Invalidate Caches

except for all the other steps, of changing MSBuild version, creating a new project and moving your code

i did that after i tabbed back in

sure..... and I'm saying you're making it worse

in an attempt to fix it, i searched on google, on jetbrains forum there were a lot of people saying: change msbuild version etc, i did that and it didnt work, i changed it back and it still doesnt work

doesnt change anything

Uninstall reinstall at this point

i just restared my pc and its still not working

i reinstalled rider, and i still have the same problem

Help -> Diagnostic Tools -> Show Log in Explorer
see if there's anything useful in there

(note that it's super verbose so it's gonna be full of stuff, including unhandled exceptions, even when everything is running fine)

im just searching for error in that file right?

more like skimming it to find anything relevant

there doesnt seem to be anything too interesting

there are a few exceptions and errors, but none of them seem to relate to the problem i have

what happens when you try to build the project?

i normaly use dotnet run or dotnet build from my terminal, which work

and if i run dotnet run it works perfectly fine:

❯ dotnet run
Something

❯

(i added a Console.WriteLine for "Something")

but in rider i cant select the project, and there is no "run button" where the Main method is

next easy thing to try: reinstall .net sdk(s)

ok

i just opened another project by accident, and it works fine, no problems, nothing

Interesting, you mentioned that didn't work before.

ye, before it didnt

now it does

new project -> just copy over the .cs files

¯\_(ツ)_/¯

ok, so for some reason, after creating another 2 projects and copy pasting the files, then opening the original one back up, it.... works...
