Validate Breakpoints location with MEF Language Service

Sajith 86

We have a Visual Studio extension that implements a legacy Language Service. We are trying to get rid of this and implement the language service in MEF now.

There is a way to validate breakpoints location in legacy language service - https://learn.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2015/extensibility/internals/validating-breakpoints-in-a-legacy-language-service?view=vs-2015

Is there anything similar in MEF language service ?

How to validate breakpoints when not debugging, in MEF language service ?

It seems, I don't see the corresponding methods for validating breakpoints in MEF language service. But are you sure that the ValidateBreakpointLocation method doesn't work in MEF language service?

@Tianyu Sun-MSFT No. There was ValidateBreakpointLocation in Legacy Language Service (Microsoft.VisualStudio.Package.LanguageService.ValidateBreakpointLocation) which gets called for validation when debugger is not running.

As we are replacing legacy language service with a MEF language service in our extension, did not find how to do breakpoints validation in MEF.

Could not find anything on this from documentation or MEF interfaces.

May I know where you checked the MEF interfaces, from here: .NET API browser?
