We have a build definition in TFS 2015 that have worked fine with Visual Studio 2015 projects and solutions. We have now decided to upgrade to Visual Studio 2017 and thus we would like to target Visual Studio 2017 in the Visual Studio build task. We have installed Visual Studio 2017 on the build agent. Unfortunately the only options available int the Visual Studio build task are 2012, 2013, 2015 and Latest. We have tried latest but it does not find Visual Studio 2017 on the build agent. It won't work with the msbuild task either.
I have a similiar issue and resolved by installing VS2017 in my build agent server and configuring MSBuild to point to my MSBuild 15.0 folder:
- Add MSBuild to your build steps
On the Advanced options, expand and fill the 'Path to MSBuild' like the image below:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin
VS2017 RTM is released recently while TFS2015 was released before. That's why there is no VS2017 option in VS Build Task in TFS2015 Server. If you upgrade your server to the latest TFS2017, you would see "Visual Studio "15" (preview)" option listed in VS Build Task which is the version for VS2017 preview. And in the feature, the option will be updated to VS2017 which is the same as VSTS.
we are facing a similar issue and it is not possible for us to update ourselves as it is maintained on a company level where we cannot take that much influence. However our team wanted to switch to VS2017 and make use of the C# 7 features. That's why we tried it as well with replacing the build steps from Visual Studio Build to MSBuild. Sadly this did not work as expected (we got some errors during the build).
As our main objective is to use the C# 7 features we looked for a way how to still achieve that at the time with Visual Studio 2015 remaining on the Build Server. We ended up using the nuget package Microsoft.Net.Compilers that, when used in a project, will use that compiler instead of the installed one. More on this can be found in this Thread.
It seems the updates to the build tools are installed via the command line of the VS2017 installer.
See the docs for details.
Just adding another thing: if you're using custom build template make sure to edit it and modify the ToolPath attribute value to:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin
