VS2017: The debugger is not properly installed. Cannot debug the requested type of code

Question

I installed Visual Studio 2017 Enterprise edition and when I am running my application getting the below error.

Answer 1

I experienced this issue after installing .NET Core SDK 2.0 without removing old .NET Core SDK's. It seems that having both causes issues.

Answer 2

Turning off Silverlight debugging solved the problem for me.

Go to the web application's Properties. On the Web tab, turn off Silverlight.

Answer 3

For me the following solved the problem:
In Visual Studio 2017, open the property page for the web project. Go to tab "Web". Select Start Action "Don't open a page. Wait for a request from an external application".

Answer 4

Try selecting a different browser (next to the green Run triangle). There is more info at https://developercommunity.visualstudio.com/content/problem/26630/the-debugger-is-not-properly-installed-cannot-debu.html, as noted by dajo.

I solved this problem for Visual Studio 2017 Community.

Clean folders:

• C:\Program Files (x86)\Common Files\Microsoft Shared\VS7Debug
