Unable to start process dotnet.exe

Question

I am attempting to setup a new work space and transfer all of my projects from my old computer to the new one. However, I am getting this error when I try to run IIS Express:

Unable to start process C:\Program Files\dotnet\dotnet.exe. The web server request failed with status code 500.

I am working in Visual Studio 2015, update 3 and I am using .NET Core RC2. Does anyone have any idea how to fix this and get my old projects running on this new machine?

Answer 1

Solution for me was to close visual studio 2017, and reopen the solution. :)

Answer 2

iisreset in cmd as Administrator did the work for me.

Answer 3

The solution in my case was deleted web.config from the root of the project. I was working on an ASPnetcore project and after a week the error started. I am unsure how that web.config file got added but once I delete that their error got resolved.

Answer 4

Visual Studio 2017 -> The fix for me was to choose the Project Name instead of IISExpress when debugging/running.

Answer 5

In my case I accidentally install dotnet for x86 platform when my VS 2017 have x64. I reinstall dotnet for platform x64 and it works fine now.

Answer 6

In your startup project be sure that you have selected the option Enable Anonymous Authentication
