You can set the StaticWebAssetBasePath with different name for each project to distinguish.

In the MicroFrontendsExample.B1Component app's project file (MicroFrontendsExample.B1Component.csproj), add a <StaticWebAssetBasePath> property to a <PropertyGroup> with a value of FirstApp to set the base path for the project's static assets:

<StaticWebAssetBasePath>FirstApp</StaticWebAssetBasePath>

In the MicroFrontendsExample.Shell app's project file (MicroFrontendsExample.Shell.csproj), add a <StaticWebAssetBasePath> property to a <PropertyGroup> with a value of SecondApp:

<StaticWebAssetBasePath>SecondApp</StaticWebAssetBasePath>

Note: The name of FirstApp and SecondApp are merely for demonstration purposes.Any base path segments that distinguish the client apps are acceptable.
