I get warnings of possible null value in markup in many places. I suspect this is because nullable context is enabled at the project level (it was convenient to leave it like that). > ![image](https://forum.dotvvm.com/uploads/default/original/1X/cf5bc67cdf7fa3766b2d3b09179c564714bf8b73.png) > > Do you have any suggestions for getting rid of this? > ![image](https://forum.dotvvm.com/uploads/default/original/1X/67480cb0d5bfd8e4b463cf0357c3a5cae56f5db6.png) > > PS: > Disabling it at the top of the .cs view model file of the MarkupControl does not resolve this. > ![image](https://forum.dotvvm.com/uploads/default/original/1X/c3611413220497503440ec8845572b4288a5847e.png) PS 2: This unfortunately blows up exponentially very easily and a nullable disabled context **is certainly not an option** for us. ![fdgdsgsdgfd](https://forum.dotvvm.com/uploads/default/original/1X/ff88692d458777c6aa930c0ccc079c814c63b3a5.png) ---

UPDATE I am not able do obtain progress with trying to disable the warnings, even though it is not to be desired to disable them in the view model: ``` #pragma warning disable CS8600 #pragma warning disable CS8602 ``` * * * Putting `[NotNull]` on properties in view model makes the markup warnings disappear but, of course, they also disappear in the view model file. ---

UPDATE Progress: ![image](https://forum.dotvvm.com/uploads/default/original/1X/a010581be7051ba083f8552621ce9d9c3fed0dc0.png) This eliminates all warnings from the MarkupControl markup. now, ❓ how do I disable specifically only for .dothtml and .dotcontrol files? ---

UPDATE on disabling for specific files: Not able to do anything with the approach posted here: [https://stackoverflow.com/a/70755376/2603874](https://stackoverflow.com/a/70755376/2603874) ![image](https://forum.dotvvm.com/uploads/default/original/1X/3b766e33a8edce7d4b1b66b79cef878930f92dd7.png) .editorconfig rules look like are ignored for DotVVM specific markup files (I tried various alternatives) while they do have effect on .cs files. So… I don’t know. ---

This is essentially the same problem as [[Validation series] Required validation for int? property gives warnings in markup](https://forum.dotvvm.com/t/validation-series-required-validation-for-int-property-gives-warnings-in-markup/146), right? > [@Simple validation crashing on just one property (+other validation issues)](https://forum.dotvvm.com/t/simple-validation-crashing-on-just-one-property-other-validation-issues/140/20): > > Do you have any suggestions for getting rid of this? I don’t know, I reported it to the VS Extension yesterday. I don’t use Visual Studio, but I doubt you can easily work around it, I think it will have to be fixed by us ---

Yes, they are the same. Good catch! And sorry, I’ve missed that - lots of stuff happening here these days. ---

no problem, I was just wondering I should report this one as another issue ---

UPDATE 😯 In a now decently 300 count of wide-rows markup: ![image](https://forum.dotvvm.com/uploads/default/original/1X/6c39699a0c0c60416d4045538cecbf7dad7aef81.png) While developing I tend to disable the warning for obvious reasons but if I get in the habbit of keeping it disabled, when I enable it again I have surprise work to do in code-behind in many places in a refactor/backtrack kinda way.
