Could not find ildasm.exe

Question

I recently upgraded to VS 2017 and uninstalled the previous VS 2015.

However when I try and build and compile my project I keep getting and error:

Microsoft.Build.Utilities.ToolLocationHelper could not find ildasm.exe

The project uses Unmanaged Exports for C# - https://www.nuget.org/packages/UnmanagedExports

I cannot understand why this message comes up and googling has showed nothing. I have made sure that the target framework is the same >> 4.5.2. But nothing will build!!

I could only find the following directories though:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools

Please help, thanks

Could it be that the uninstall of VS 2015 remove the file you want to use? Just a thought. — Just a HK developer, Jun 30 '17 at 01:46
@KenWhite- I have looked on my hard drive, I have the ildasm.exe for the NET 4.6.1 tools but no folder for NET 4.5.2. Whatever I try and install will never get me back that folder. — Zeller33, Jun 30 '17 at 08:29

Update with the latest version of UnmangedExports. In my case, it was version 1.2.7

I had the exact same problem.

I installed the Unmanaged Exports again and the problem was solved.

There is a newer open source version of Unmanaged Exports on github. I'd recommend using this one as it will support later version of .NET framework - https://github.com/3F/DllExport – Zeller33 Jul 19 '17 at 09:06

Based on this issue: https://github.com/nefarius/ViGEm/issues/29

You should reinstall VS2017. Uninstall all of your VS15/17 versions and install it again with the VS17 installer.

If reinstall doesn't resolve problem, remove folder packages\UnmanagedExports.1.2.7 and then, in Package Manager Console, install package using command posted by @Ale:

PM>Install-Package UnmanagedExports -Version 1.2.7
