It has just begun recently. I tried all the solutions that I can find on Stack and other forums, but nothing has worked so far.
When I try to start debugging an Azure working role, this is as far as I can:
The debug window says: The program '[2208] WaIISHost.exe' has exited with code 0 (0x0).
I am running Visual Studios in administrative mode, with the correct project set as launch, and using IIS Express as the dev server.
I tried to create a new Azure worker role with the same base project, but that didn't work. System event logs do not contain any information. I tried to reinstall VS2015 and separately Azure SDK (v.2.7.1), without changes. When I look at the computational emulator before it disappears, it says:
[fabric] Role Instance: deployment27(250).Web.0 [fabric] Role state Unhealthy [fabric] Role state Stopped
However, I can start other role-playing projects in the solution, which makes me think that something was supposed to go bad in a project tied to a broken role. At this stage, I have no ideas, so any help is greatly appreciated.
UPDATE
Viewing the WallSHost.log file inside C:\Users\<UserAccount>\AppData\Local\dftmp\Resources\<GUID>\directory\DiagnosticStore gives me an Invalid name error:
