Question

Hi,
I've a VS2022 solution with several project. Basically it's a .NET 6.0 SPA app with WebAPI.

Every time I try to perform an edit and continue in my C# code, VS fails with this kind of error:

Error BC36970 Failed to emit module XXXX Changing the version of an assembly reference is not allowed during debugging: XXXX changed version to "1.0.0.0"

I cannot find a way to fix it, and so I'm not able to use edit and continue. Any idea?

Hi @Topogigio ,

Welcome to Microsoft Q&A!

Please update your Visual Studio 2022 to the latest version and create a new project to verify if the issue persists or not.

Meanwhile, please try to delete the .vs folder in your project folder and rebuild your project.

By the way, you can refer to the similar issue and check if you have the same behavior or not:

Hi, VS is updated of course.

The problem sometimes goes away for a while, then it returns after a few days.

deleting .vs folder does not fix nothing
