The type or namespace name '“Namespace”' could not be found in the global namespace (are you missing an assembly reference?)

Question

I am trying to build a solution and getting the following error:

Severity Code Description Project File Line Suppression State Error CS0400 The type or namespace name 'CMSInstall_Controls_WizardSteps_CollationDialog' could not be found in the global namespace (are you missing an assembly reference?) Fortius.CMS D:\\Kentico10Migration\\GithubMegha\\Fortius.CMS\\CMS\\CMSInstall\\install.aspx.designer.cs 390 Active

Designer file is not recognising

"CMSInstall_Controls_WizardSteps_CollationDialog"

/// /// ucCollationDialog control. /// /// /// Auto-generated field. /// To modify move field declaration from designer file to code-behind file. /// protected global::CMSInstall_Controls_WizardSteps_CollationDialog ucCollationDialog;

But another solution file have same install.aspx install.aspx.cs install.aspx.desginer.cs files present but no errors while build it.

Answer 1

I fixed the issue:

Issue was the class which is provided in designer file was present in a file which was excluded in the solution. I have included all files and error went away!

Yipieee!!
