Not sure if this is related but I also reported a Blazor intellisense issue to VSfeedback and that issue is "under investigation" for over a month now.

Blazor deserves great tooling support from Visual Studio!

Thanks for contacting us.

We would need more information in order to troubleshoot this. A minimal repro-project that illustrates the issue (we don't know what's at play here, how big the project is, how many components in it, etc) as well as likely some information like a performance trace of visual studio so that we can better understand what is causing the slow down as well as some details about your environment, like what plugins/extensions are you using.

we have pretty much the same problem. we have a relatively large project with ~250 components and its really slow. rebuilding helps almost everytime, sometimes you have to restart vs. often it also help to close & reopen the razor file to get of the error messages.

We have this problem for a long time and we are currently using the 16.4.0 Preview 3 Professional Edition.

@oiBio Could you report this through the "Send feedback" dialog in Visual Studio and attach a repro with the report? Here are the steps to follow https://docs.microsoft.com/en-us/visualstudio/ide/how-to-report-a-problem-with-visual-studio?view=vs-2019#record-a-repro

@javiercn : Do you have any idea about why intellisense is not working in the immediate window? ( Default template, just break on the weather service OnInitializedAsync , type ForecastService + . in the immediate window -> nothing is shown)

javiercn commented 5 years ago

@Postlagerkarte I have no idea, as that is a tooling issue and I'm not super familiar with the area.

With regards to https://github.com/aspnet/AspNetCore/issues/17002#issuecomment-552845139 I don't think that issue is necessarily tied to this one. We do our best to look at all the issues in a timely fashion, but I hope you understand that sometimes there are multiple teams involved in root causing an issue and we need to balance other things which can sometimes take time,

We're closing this issue as we haven't seen community involvement and we need more information to reproduce the problem. If you have more details about the issue add a reply here with the new information and we'll re-evaluate the issue.
