"GenerateResource" task CLR2 runtime error

Clean and rebuild solution worked for me.

Adding this in each project is a cumbersome task. So you can set it in the environment variables.

Click Start>> Right-click Computer >> Properties >> Advanced system settings >> Click Environment Variables button to open the dialog, then under the System variables section, click New… button, type the Variable name = DISABLEOUTOFPROCTASKHOST, and type the Variable value = 1, then click Ok.

This fixed the issue on my machine:

To resolve it, go to your csproj file and add the following line under the default property group:

<PropertyGroup>
    ...
    <DisableOutOfProcTaskHost>true</DisableOutOfProcTaskHost>
</PropertyGroup>
