I am using VS 2019. Once the project is cloned from bitbucket, I am able to build the solution. If I try to build after cleaning the solution or rebuild, I am getting this error.

Severity Code Description Project File Line Suppression State Error Could not run the "LC" task because MSBuild could not create or connect to a task host with runtime "CLR4" and architecture "x64". Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\amd64\MSBuild.exe" exists and can be run.

I have updated VS but it did not help.

  1. Updated VS 2019
  2. deleted .vs folder obj folder and debug folder
  3. restarted the machine

Based on experience,

  1. You can try to add the following code in the csproj file: (unload the project, then double-click the project to enter)
<PropertyGroup>
   <GenerateResourceMSBuildArchitecture>CurrentArchitecture</GenerateResourceMSBuildArchitecture>
   <GenerateResourceMSBuildRuntime>CurrentRuntime</GenerateResourceMSBuildRuntime>
</PropertyGroup>
  1. Add an environment variable DisableOutOfProcTaskHost and set its value to true. Or set it to 1.

Update:

It was due to crowdstrike running in the machine.

  • Do you have any extensions installed that affect msbuild, try disabling them. You can also try to reinstall vs2019 using installer, but I suggest you use the latest version of 2022. This link may help you. https://developercommunity.visualstudio.com/t/msbuild-amd-x64-not-working/1387989?viewtype=solutions – Jiale Xue - MSFT Jan 18 '23 at 09:02
  • i have installed VS 2022 yesterday, still same issue. Need to check on extensions – Roopa Rai Jan 18 '23 at 09:04
  • Maybe you need to try removing msbuild, and reinstall https://learn.microsoft.com/en-us/visualstudio/msbuild/walkthrough-using-msbuild?view=vs-2022#install-msbuild. Do you have the same problem in your new program? – Jiale Xue - MSFT Jan 18 '23 at 09:05
