Brand new machine with VS 2015 only b0rks

[ogreenz]

When running BDN 0.9.4 on a brand new machine with VS 2015 only installed I get this beatiful thing:

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Build.Framework, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Looks like there is no support for Microsoft.Build.Framework v14.0 (which is the only thing I have installed in the GAC)...

Thanks for reporting the bug. It is already fixed #132, but not yet released (will be part of 0.9.5 version). If you do not want to wait for the release please Install msbuild 12

[adamsitnik]

I was not 100% right. In #132 the user was getting FileNotFoundException, but you got FileLoadException which has not been handled yet. I added the right handler. Thanks once again and sorry for inconvinience!

I'm getting the following now this morning when I reverted to 0.9.3

Is it possible to generate a vs12 solution instead of a vs14?

[niemyjski]

We are using VS12 build image

[adamsitnik]

Hi @niemyjski The bug is already fixed, but it's waiting for the Release (probably end of the next week). For .NET 4.5 target we are going to reference MSBuild 12 dlls, for .NET 4.6 MSBuild 14 dlls. We will also have a fallback mechanism in case when dll are not found we will just execute bash script that will do simple call to msbuild

As far as I can tell this should have been part of 0.9.5 but this still happens to me on a brand new machine with 0.9.5

[adamsitnik]

@damageboy which .NET framework is your benchmark project targeting? It should be .NET 4.6 or higher

[niemyjski]

I'm targeting 4.5 on a machine that only has. Vs2015 installed and I get tons of errors with the latest version

[adamsitnik]

BenchmarkDotNet for .NET 4.5 references MSBuild12 (VS 2013), for .NET 4.6 MSBuild 14 (VS 2015).

Could you please try removing BDN form your benchmark project, upgrade it to .NET 4.6 and install BDN 0.95 ?

[niemyjski]

Negative, we reference 4.5 explicitly because there are issues with using
the .net 4.6 compiler / toolchain when targeting pcl projects. As such
everything that runs as part of this build cannot be any higher than 4.5

Thanks

FYI I just just got this exact error with Visual Studio 2015, targetting .NET 4.5.1 and referencing the latest nuget (0.9.5). We're currently referencing 4.5.1 for the time being.

[adamsitnik]

@colgreen could you give it a try with 0.9.6? It has been released an hour ago
