Is Visual Studio for Mac not able to build or run Blazor WebAssembly apps, or am I missing something? However, the Blazor WebAssembly App template does not show up in Visual Studio for Mac, even after restarting:Īnd if I create a Blazor WebAssembly app from the CLI as follows, it builds but does not run: dotnet new blazorwasmĪnd if I try to run it in Visual Studio for Mac I get this error:Ĭannot open assembly '/Users/my.username/projects/blazor/BlazerWasm/bin/Debug/netstandard2.1/BlazerWasm.exe': No such file or directory.
