Visual Studio 2017 Option: Use Managed Compatibility Mode per project

Question

I work on two different projects. One is an asp.net web project, the other an addin for an arcmap.exe. For debugging the addin the option \"Use Managed Compatibility Mode\"

Answer 1

The solution for now is without an extension. As described in Switching to Managed Compatibility Mode in Visual Studio 2013 it is possible to add a configuration in the .csproj file by hand:

<PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
    ...
    <DebugEngines>{351668CC-8477-4fbf-BFE3-5F1006E4DB1F}</DebugEngines> <!-- add this line -->
    ...
</PropertyGroup>

This has to be done for the "Startup Project". After setting the property for the project, The option "Use Managed Compatibility Mode" can be unchecked in Settings - Debug.
