Can't get hot reload to work properly

[RemcoW2002]

I've been at this pretty much all afternoon so my brain is rather fried, apologies for any spelling mistakes or overlooking obvious solutions.

I come from VS Code so Visual Studio isn't really my ideal solution, I figured I just adapt to it but it seems there is no way to get syntax highlighting for liquid files? This is already my first question, is there no way to have syntax highlighting for Visual Studio on liquid files? How do you guys generally run a project, especially if it's based on liquid rather than razor, do you just accept you can't read white text, , launch it in VS Code instead and have none of the hot reload issues, or again, am I missing some very obvious point. Also again, I am a total Visual Studio noob so sincere apologies if the solution is obvious.

I decided to just use VS Code, I was given a project in which there were liquid files, it seems to be based on TheBlogTheme, the person providing me with this is on holiday, so I can't really ask them anytime soon, and just so you know my assignment was to figure out if Orchard CMS is a nice to use system. Particular figuring out how to easily convert to razor pages

So I made a new theme, and one of the first things I noticed in VS Code, is that hot reloading stopped working (it works for the liquid based theme which is connected to the same web app). After some research I found out that razor is different and was suggested to try out various packages or changes to the manifest.cs or csproj files and tried solutions/suggestions from here: #16504.
I Tried pretty much everything, all of them either crashed my app or didn't work, So I eventually moved to using 'dotnet watch'. This though crashes my app when I edit particular items, in VS Code it doesn't give me any errors, so I switched to Visual Studio

Though here I am running into the same issues, though hot reload is mostly working on my project, for certain parts not only does it not work, it crashes my build. Giving me the following error:
source\repos\Hijc2.OrchardCore\Hijc2.OrchardCore.sln(0,0,0,0): Cannot apply changes -- unexpected error: 'Unexpected null - file EditSession.cs line 699'. In particular it crashes when I try to apply any changes with hot reload to my MenuItemLink-ContentMenuItem.cshtml file. But it goes for all my menu related .cshtml files

If take the liquid files from the liquid solutions and bring them in my razor based theme, they work and I can update them and they hot reload, if I change just one of those files to a razor based version, then hot reload stops working and it breaks, so it's somehow a razor based problem but at the same time other razor files hot reload fine.

I've deleted all the obj and bin files in all folders of my project which did not solve my issue either. Though again it's limited to only a part of my website it's still very inconvenient especially as I am just learning about Orchard and Razor so constantly testing stuff and then having to rebuild each time is quite the pain in the ass.

Ideally I want my razor project to just work in vs code with hot reloading

Again I'm very sorry if the solution is obvious

I never really use Liquid in templates, but when looking at OC code, this helps: https://marketplace.visualstudio.com/items?itemName=igorfle.VSLiquidSyntax This is basically all the Liquid support VS has.

For hot reload, check out #15946 too.

Alright thanks for the response, I got it working now except there is still one, rather odd issue, whc

I am converting from liquid to razor and tried converting the menu item to cshtml, at this point I hae already converted like 15 files or so without issue that all hot reload fine and as expected,

But any Menu related contenttype/item I try to edit in .cshtml causes the application to crash saying it causes issues for the hot reload and the error messages only letting out this error message:
source\repos\Hijc2.OrchardCore\Hijc2.OrchardCore.sln(0,0,0,0): Cannot apply changes -- unexpected error: 'Unexpected null - file EditSession.cs line 699'.

Which is rather unhelpful, is this like a known issue? If I keep the menu items, which I guess is a temporary solution for now, as a liquid file, then it works fine, and hot reloads as well. As soon as I change that to .cshtml I get the issues again

This looks more like an issue with hot reload. EditSession.cs is not an OC file.

Liquid files are not actually compiled, but parsed, so they're not really utilizing hot reload.
