各位好，我现在在Visual Studio里开发Blazor WebAssembly独立项目，给MainLayout页面加了本地的razor.css文件，但项目好像找不到这个样式文件，样式完全没生效。有没有遇到过同样问题的朋友能给我指点一下？谢谢！

我的MainLayout.razor代码： #

<MudLayout>
    <MudBreakpointProvider>
        <MudHidden Breakpoint="Breakpoint.Xs"
                   Invert="true">
            <MudAppBar Elevation="1"
                       Class="appBar">
                <MudToggleIconButton Class="mr-2"
                                     @bind-Toggled="@Drawer_Open_Close"

               Style="bottom: 0; top: unset;">
        <MudText Typo="Typo.body1"
                 Class="mx-auto"
                 Color="Color.Dark" Align="Align.Center">
            <b>
                //Footer
            </b>
        </MudText>
    </MudAppBar>
</MudLayout>

对应的razor.css代码： #

body {
}

.footer {
    height: 50px;
}

/* Или ако искате да стилизирате MudAppBar класа: */
.mud-appbar.footer {
    height: 50px;
    background-color: var(--mud-palette-background);
    border-top: 1px solid var(--mud-palette-lines-default);
    position: fixed;
    left: 0;
    right: 0;
    z-index: 100;
    display: flex;
    align-items: center;
    justify-content: center;
}

.mainContent {
    padding-bottom: 70px;
    min-height: calc(100vh - 120px);
}

我自己试了一些方法但没解决，比如检查了选择器拼写，有没有其他朋友能给点思路？比如Blazor WASM的样式隔离是不是有什么特殊要求？或者和MudBlazor的样式有冲突？ #
