title: How to build .Net Core Application from C# code using "BuildManager"?
body: <p>I want to build .Net Core 2.1 Console application from C# code. I am using BuildManager to build solution.</p>
  
  <pre><code>               using (var buildManager = new BuildManager())
                  {
                      var bp = new BuildParameters(projectCollection)
                      {
                          Loggers = new List&lt;ILogger&gt;
                          {
                              logger
                          },
                          OnlyLogCriticalEvents = false,
                          DetailedSummary = true,
                          NodeExeLocation = @"C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Professional\\MSBuild\\Current\\Bin\\MSBuild.exe"
                      };
  
                      var buildRequest = new BuildRequestData(
                          "projectFullPath",
                          globalProperties, null, new[] { "Build" }, null,
                          BuildRequestDataFlags.ReplaceExistingProjectInstance);
  
                      BuildSubmission submission = null;
  
                      buildManager.BeginBuild(bp);
                      submission = buildManager.PendBuildRequest(buildRequest);
  
                      buildResult = submission.Execute();
                      buildManager.EndBuild();
  </code></pre>
  
  <p>I already have set Environment Variables like this:</p>
  
  <pre><code>        Environment.SetEnvironmentVariable("MSBuildExtensionsPath", globalProperties["MSBuildExtensionsPath"]);
          Environment.SetEnvironmentVariable("MSBuildFrameworkToolsPath", globalProperties["MSBuildFrameworkToolsPath"]);
          Environment.SetEnvironmentVariable("MSBuildToolsPath32", globalProperties["MSBuildToolsPath32"]);
          Environment.SetEnvironmentVariable("MSBuildSDKsPath", globalProperties["MSBuildSDKsPath"]);
          Environment.SetEnvironmentVariable("RoslynTargetsPath", globalProperties["RoslynTargetsPath"]);
  </code></pre>
  
  <p>Where globalProperties:</p>
  
  <pre><code>            Path.Combine(programFilesX86, @"Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\msbuild.exe"),
              Path.Combine(programFilesX86,
                  @"Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe"),
              Path.Combine(programFilesX86, @"Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe"),
              Path.Combine(programFilesX86, @"Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe"),
              Path.Combine(programFilesX86, @"MSBuild\14.0\Bin\MSBuild.exe"),
              Path.Combine(programFilesX86, @"MSBuild\12.0\Bin\MSBuild.exe")
  </code></pre>
  
  <p>And Now I have build error.</p>
