Project doesn't build from CLI, builds from VS, but Intellisense doesn't believe it (Microsoft.IdentityModel namespace issue)

[lioobayoyo]

I installed .NET Core 2.1.402, updated my Visual Studio 2017 Professional to 15.8.5 and cloned the repo as per the README.

The application builds successfully from Visual Studio .

However, everything related to Microsoft.IdentityModel is underlined by Intellisense, despite some restarts. (see screenshot)

I also tried to do dotnet restore in case it was some external package issue, but apparently no NuGet package are needed here.

It's a bit problematic to work correctly with a tool believing you are not using correct code.

I digged and tried to use dotnet build instead, and it seems I get a related error :

(sorry for the French in the screenshot, but basically a targeted project was not at all installed in the indicated directory in .NET SDK...)

What could be the cause / fix for this ?

Seems to me like an issue in your VS.NET installation. Try these steps

1. Clean solution. close and delete bin and obj folders and any .user files and reopen.
2. remove and add Nuget packages that complain
3. Last try repairing vs.net

I think it's a VS issue. you might want to delete your .suo?

also @lioobayoyo : did you try to move the source folder closer to the root of your hard disk (long path issue?)

Actually, this looks like an issue of understanding from myself. the project is .NET 4.5, not .NET Core 2.1, right ?

(NB : @kalyankrishna1 : did you suggestion for fix install of VS, no change

@jmprieur I already taken the project in a folder directly under the root folder of my disk. When a problem arise from a file path length issue, my VS2017 just crashes at the project opening ;) )

This should now be fixed with VS 2017.8.8
