用于 Microsoft Visio VSTO 解决方案的 Visual Studio 2022 热重载实际上并不起作用

Question

Even though Microsoft says that the new hot reload functionality works for pretty much any .NET project, and Office VSTO is not mentioned as an exception, I assumed that hot reload would work pretty well.

However if I make even an insignificant change to any function in my ThisAddIn object, I get this error for pretty much any Visio interop object used in the function:

Error BC37230 Cannot continue since the edit includes a reference to an embedded type: 'Shapes'. ExtendedVisioAddin1 1 Active

I could add just this line:

Dim A as integer = 1

and I get these errors and hot reload isn't working.

Is hot reload incompatible with the .NET wrappers around COM interop objects? If I could get hot reload to work with Office VSTO solutions it would be a pretty great timesaver. Thank you for your help and advice!

Answer 1

I have never heard about such features implemented for the unmanaged solutions like VSTO. Only standalone applications can be reloaded quickly (have got the hot-reload feature onboard).
