Error in azure app service with net 5

[jarandal]

I having this error when running my app in azure app service in windows with net 5.

Could not find a part of the path 'C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref'

I think is beacuse that directory do not exist on net 5,

Locally my code runs.

¿any ideas?

Could not find a part of the path 'C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref'.\r\n ---> System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref'.\r\n at System.IO.Enumeration.FileSystemEnumerator1.CreateDirectoryHandle(String path, Boolean ignoreNotFound)\r\n at System.IO.Enumeration.FileSystemEnumerator1.Init()\r\n at System.IO.Enumeration.FileSystemEnumerator1..ctor(String directory, Boolean isNormalized, EnumerationOptions options)\r\n at System.IO.Enumeration.FileSystemEnumerable1..ctor(String directory, FindTransform transform, EnumerationOptions options, Boolean isNormalized)\r\n at System.IO.Enumeration.FileSystemEnumerableFactory.UserDirectories(String directory, String expression, EnumerationOptions options)\r\n at System.IO.Directory.InternalEnumeratePaths(String path, String searchPattern, SearchTarget searchTarget, EnumerationOptions options)\r\n at System.IO.Directory.EnumerateDirectories(String path)\r\n at Mono.TextTemplating.CodeCompilation.RuntimeInfo.FindHighestVersionedDirectory(String parentFolder, Func2 validate, SemVersion& bestVersion)\r\n at Mono.TextTemplating.CodeCompilation.RuntimeInfo.GetDotNetCoreSdk()\r\n at Mono.TextTemplating.CodeCompilation.RuntimeInfo.GetRuntime()\r\n at Mono.TextTemplating.TemplatingEngine.GetOrCreateCompiler()\r\n at Mono.TextTemplating.TemplatingEngine.CompileCode(IEnumerable1 references, TemplateSettings settings, CodeCompileUnit ccu)\r\n at Mono.TextTemplating.TemplatingEngine.CompileTemplateInternal(ParsedTemplate pt, String content, ITextTemplatingEngineHost host, TemplateSettings settings)\r\n at Mono.TextTemplating.TemplatingEngine.CompileTemplate(ParsedTemplate pt, String content, ITextTemplatingEngineHost host, TemplateSettings settings)\r\n at Sonda.Core.Tools.T4.ToolTemplateGenerator.ProcessTemplate(ParsedTemplate pt, String inputFile, String inputContent, String& outputFile, TemplateSettings settings) in /home/administrador/agente/_work/1/s/Backend/Repositorio/Sonda.Core.Tools/T4/ToolTemplateGenerator.cs:line 43\r\n at Sonda.Core.Tools.Business.DagWizardBO.Generate(Dictionary2 properties, String template, String outputFolder, ILogger _logger, ToolTemplateGenerator& generator) in /home/administrador/agente/_work/1/s/Backend/Repositorio/Sonda.Core.Tools/Business/DagWizardBO.cs:line 501\r\n at Sonda.Core.Tools.Business.DagGeneratorBO.Generate(GenerateInput input, Boolean permisosOn) in /home/administrador/agente/_work/1/s/Backend/Repositorio/Sonda.Core.Tools/Business/DagGenerator.cs:line 229\r\n --- End of inner exception stack trace ---\r\n at Sonda.Core.Tools.Business.DagGeneratorBO.Generate(GenerateInput input, Boolean permisosOn) in /home/administrador/agente/_work/1/s/Backend/Repositorio/Sonda.Core.Tools/Business/DagGenerator.cs:line 233\r\n at Sonda.Core.Tools.Api.Controllers.DagGeneratorController.<>c__DisplayClass7_0.<<Generate>b__0>d.MoveNext() in /home/administrador/agente/_work/1/s/Backend/Repositorio/Sonda.Core.Tools.Api/Controllers/DagGeneratorController.cs:line 46\r\n--- End of stack trace from previous location ---\r\n at Sonda.Core.DbConn.UnitOfWork.UnitOfWork.Execute[T](Func1 function)",

I make it work checking if directory exists.

https://github.com/mono/t4/blob/main/Mono.TextTemplating/Mono.TextTemplating.CodeCompilation/RuntimeInfo.cs

			// it's ok if this is null, we may be running on an older SDK that didn't support packs
			//in which case we fall back to resolving from the runtime dir
			String refAssembliesDir = null;
			var dotNetRefsDir = Path.Combine (dotnetRoot, "packs", "Microsoft.NETCore.App.Ref");
			if (System.IO.Directory.Exists(dotNetRefsDir)) {
				refAssembliesDir = FindHighestVersionedDirectory (
					Path.Combine (dotnetRoot, "packs", "Microsoft.NETCore.App.Ref"),
					d => File.Exists (Path.Combine (d, $"net{hostVersion.Major}.{hostVersion.Minor}", "System.Runtime.dll")),
					out _
				);
			}
