Description
Couldn't find an existing issue for this one (but could've missed it).
Compile the following piece of VB code in VS2015 with the "Implicit Type; Object Assumed" option set to "Warning":
Module Module1
Sub Main()
' Causes build to fail
Dim sEvent = String.Concat(" Error:", "Whatever")
' Won't cause build to fail
Dim sEvent2 = String.Concat(" Another: ", "Whatever")
End Sub
End Module
Both variable declarations will trigger a BC42020 warning. However, when the compiler encounters the sEvent declaration, it will include the line in the compiler output right after the warning, because it has the text " Error:" (leading space makes a difference).
This causes MSBuild/VS2015 to think the build failed and generate an strange error entry in the Errors window, even though only warnings were emitted during the build.
