No intellisense in Blazor Hosted WebAssembly Project: VS 2019 Preview 2.1 #5174

nssidhu commented 4 years ago

I am not getting any intellisense for Blazor WebAssembly Hosted Project( Client Side). The problems mainly occur in the Client(Blazor) Project. Server & shared Project i do get intellisense. Feels like i am working in Notepad.

Not sure if this is releated, but i keep on getting this error in Vsiaul studio(On the Top bar)
