I'm having a strange issue with my CSHTML files this morning. One moment everything is working fine... then next moment, everything is still working, but all my code highlighting for anything with # infront of it has gone.
The project still compiles and runs fine, but I'm getting red highlights where ever there is a
Code block.
There are loads of posts for Conditional Formatting on this site, but they all suggest changing the code. I don't want to change any code, it's all working fine. I just want to get the yellow colouring behind the # back.
It's all working fine in the aspx files. I can't think of what I did to turn this off.
Edit
I've created a new project and copied every code file over manually.
This is how it looks in the new project.
And like this in the old
That's a bug in Visual Studio. You can't do anything about it. It's just that the dudes at Microsoft didn't get Syntax Highligthing and Intellisense right in Razor views. Hopefully they will in some future version of Visual Studio.
There's nothing wrong with the code you have shown. It works perfectly fine at runtime. Just the tools you are using aren't capable of realizing that.

When trying to open the form deisgn it says values cannot be null. (Parameter 'baseName'). I still can run the system without error. Dont know how to fix it and have to change some gui design. Help me its for my school tnx
I had this problem this morning and a few hours later I decided to just start over and copy the code from the old project to the new empty project. Everything is working in the new copy of the project. I copied from old to new by drag-n-drop. I copied all the UserControls before I copied anything that uses them, and built, then copied over the remaining things, and went through all the errors caused by the change in name of the top-level Namespace.
(All of the Namespace errors were in the .Designer.vb files. I have posted elsewhere "never edit those files by hand unless you know what you are doing." This case was one of the rare exceptions.)
I had the OP's problem that when I tried to open a Form in the designer, I got the message
Value cannot be null. (Parameter 'baseName')
It didn't matter if I tried to open the Form in Solution Explorer or by pressing Shift-F7 in the Form's code window. However, sometimes Shift-F7 resulted in a wait cursor followed by silence - no error message.
Like the OP, the project did run without errors (well, same bugs as before but you know what I mean).
Another symptom: If I launched VS and tried to open the Form designer before Intellisense was initialized, instead of the other error, the window that should show the layout of the Form showed this instead:
File path: full path of the file I was trying to open
Frame GUID: 2c01570-c72c-11d0-88c3-00ac0c9110049
Frame mode: VSFM_MdiChild
Error code: 0x80131500
There are no MDI containers in my project. It's a reference to VS 2019.
The same error occurred in every Form and UserControl in the project.
The same error occurred in any new Form or UserControl that I added to the project.
The error did NOT OCCUR in any and all other projects built in VS 2019 with a target of .Net 5.0
The error DID OCCUR with the same project on another machine running a clean install of a later version of VS 2019.
Attempts to Clean Solution or Clean Project failed, with a generic error message, it was something like "Clean Project failed."
Nothing about these problems appeared in any event logs.
Every time the problem happened, when I shut VS, one process was left running (per TM).
Here are some other things I did to try to suss it:
Ran a repair install on VS 2019 and reboot.
Opened each and every VS-generated file in another project and compared them line-for-line (most are text) against the corresponding files in the broken project. No data-independent differences.
Searched exhaustively with 3 search engines and many terms for someone else that posted about this error. This is the only post I found.
Deleted, renamed, or moved files that are automatically generated by VS, including some Json files, XMLs, and caches.
What I did not try:
Roll back the code to the most recent commit.
Uninstall VS 2019 completely, reboot, install VS 2019 as if an initial installation.
Just had the same experience. I took me a while before I got everything to work again, but the clue in my case was that I had added a new item to my project, and for some reason I had managed to delete the file name in the process so the only thing left was 3 new files with only the extensions .resx, .cs and .Designer.cs
I quickly deleted the ".cs" file but forgot the rest.
Suddenly I was unable to open my main form in the designer - and the “Value cannot be null. (Parameter 'baseName')” started to appear. It was only affecting my main form.
I tried almost everything described above except the reinstalling part.
But then I deleted ".Designer.cs" and ".resx" from within visual studio (Solution Explorer), and then the problem went away.
I started getting this error after using a hack to support generics forms (e.g. MyForm). The designer generated a file:
MyForm.resx
which worked for design time (even with the form being generic) but crashed at runtime. My hack was to rename the .resx file:
MyForm`1.resx
However that is when the Designer stopped working. It stopped working for ALL forms/user controls in entire solution (not just the generic I was experimenting with). I assume there is some kind of process that crawls all the resx files whenever you open any Designer and that is the source of the Exception.
I was able to work around the issue by:
Renaming the resx back to its non generic title (i.e. MyForm.resx)
Restarting visual studio.
Typically when I compile a project I am working on in Codewarrior, the Problems window displays the errors and warnings it finds. From there, I am able to click on the errors and I will be linked to the location of the error in the code. In the current project I am working on, the errors are displayed in the problems window, but they do not link to the error. It shows the correct file and path, but the hyperlink to the location in the code is broken. In the console window, I can use the Next/Previous error buttons to navigate to error, but I can't do this from the Problems window - which I find easier to read. I know that this error is limited to this project, because I have opened other projects since this started happening and do not experience this problem in those projects. When I started this project, I copied an existing Codewarrior 10.5 project that does not have this issue and began changing names and editing. I have a suspicion that I might have missed something during this conversion process, but I am running out of places to look.
I'm not sure the exact reason for this error, but I did correct it by deleting the folders in the workspace folder and re-importing the project.
I have a scala project that I'm working on in Intellij. When I opened it up this morning, suddenly none of the code is being analysed properly. The main things I've noticed are that it says every variable is unused (even when it's used in the next line), it doesn't show an error if I try to use a variable that doesn't exist, and I don't get any errors if I try to use a class I haven't imported. TODOs also don't come up in blue.
Does anyone know if there is some sort of setting that somehow could have changed that would affect this? The problem only happens in this one project, all of my other projects are fine.
Edit: I have tried closing it and opening it again, invalidating the cache and restarting and restarting the entire computer.
Edit 2: I forgot to say, if I try to run a test it will come up with the correct compilation errors for things that shouldn't work, but it still doesn't show the error in the code itself.
I'm still not sure why it happened, but I fixed it. I deleted the .idea folder and re-imported the project, and everything was analysed properly.
I am having a very strange situation over here.
I refered to the UWP samples and tried Custom Media transport controls sample. I ran it and it was working just fine, like its supposed to work. But then I tried and made my own project and I copied exactly everything which was in sample project not even name of file or folder was different. And then when I ran that project it gave me debugger unhandled exception and open App.ig.cs some file like this and when i continue it stop debugging. Below is the attached snapshot of that error. Any help is appreciated this is a really strange error for me as it makes no sense at all.
Note: I have tried to run it in both blend and visual studio
I solved it by simply ignoring the style of transport controls provided in the sample, for some reason that style was not able to verify some properties so I deleted that file and made my own style file, I copied the style of default media controls and edited them, it worked for me :)
For some reason, I can't set a breakpoint in #functions when using Visual Studio 2013. Here's an example:
However, the same kind of breakpoint works in Visual Studio 2012:
If you move the #functions block up to the top of the razor page in VS2013 you can set a breakpoint in #functions once again.
You cannot set a breakpoint in #functions if the block is somewhere in the HTML.
Anyone know why? Maybe a bug? This is a big inconvenience if you're migrating an web app from MVC4 or earlier where #function blocks appear in the HTML.
This seems like a known issue. See reported bug in MS Connect.
Description:
"After my upgrade to VS 2013, I am no longer able to debug javascript within MVC razor files. "
http://connect.microsoft.com/VisualStudio/feedback/details/807088/unable-to-debug-javascript-from-the-vs-2013-ide-unable-to-set-breakpoint
I had all of the same issues with "This not a valid location for a breakpoint", and I also had no code highlighting or intellisense on any of the Razor code. None of the solutions I could find resolved it. Primarily because my issue was due to a really dumb oversight on my part, but just in case anyone finds themselves here and have made the same mistake, I thought I'd share it.
If you did not physically create the view yourself in Visual Studio, like if it was created with a NuGet package (Umbraco in my case), or if you opened an existing solution that isn't yours...The view may not be included in the project. You may see something like this
Notice that the Homepage.cshtml file is in there and I can edit it, compile it, render it etc. But I could not insert a breakpoint anywhere. Right clicking on the file and Selecting "Include In Project" was the fix for me.
What worked for me was Excluding the file then Including it again. Picked up the Breakpoints straight away.
Hope it helps!
What helped me overcome this issue was enabling the "ASP.NET" option in the project-properties. See the screenshot:
