Bug 19803 – Add support for latest VS 2019 Preview - 16.1.0

I had installed VS 2019 + VisualD v0.49.0 and everything was working smoothly. Thanks for the awesome work, by the way! Today I upgraded my VS 2019 to "16.1.0 Preview 1.0" and I got this message when trying to build a dmd: 1>C:\Program Files (x86)\VisualD\msbuild\dcompile.targets(136,5): error MSB4062: The "dbuild.CompileD" task could not be loaded from the assembly C:\Program Files (x86)\VisualD\msbuild\dbuild.16.0.dll. Could not load file or assembly 'Microsoft.Build.CPPTasks.Common, Version=16.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. 1>Done building project "dmd.vcxproj" -- FAILED. After the update, the version of "Microsoft.Build.CPPTasks.Common.dll" is 16.0.28803 (under "C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\MSBuild\Microsoft\VC\v160"), so I suspect that the problem is due to the different version. This may be difficult to solve right now, as the latest VS SDK Nuget package is 16.0.200 (https://www.nuget.org/packages/microsoft.visualstudio.sdk), so I don't know whether that would be compatible with VS 2019 16.1.0.

Welcome to DLL/assembly hell. Try https://github.com/dlang/visuald/releases/tag/v0.49.1

Thanks!
