C#Blazor这是可行的，但我有错误

也许我做错了什么，或者VisualStudio出了问题，请建议

错误是：

"Severity   Code    Description Project File    Line    Suppression State
Error   CS0115  'TechProfile.OnInitializedAsync()': no suitable method found to override

程序按预期工作，但如果错误是真的，我不希望出现错误。另外，如果有人知道如何根据我的代码查看Blazored.LocalStorage的模型，请告知我，我想知道如何将其放在单独的cs文件中并调用一次，而不是一直设置它

好的，这是我的剃须刀组件

@page "/profile/techprofile/techinfo"
@using TechHelper.Model
@inherits TechModel
@inject Blazored.LocalStorage.ILocalStorageService oLocalStore
 
<h3>Technician Profile</h3>


    <table id="TechProfile" class="ProfileTable">

        <thead colspan="2"> Profile Information </thead>

        <tr>
            <td>Full Name: </td>
            <td><input type="text" id="TechName" class="inputfield" @bind-value="@TechName" /></td>
        </tr>
        <tr>
            <td>Standard ID: </td>
            <td><input type="text" id="StandardID" class="inputfield" @bind-value="@TechID" /></td>
        </tr>
        <tr>
            <td>Email Address: </td>
            <td><input type="text" id="TechEmail" class="inputfield" @bind-value="@TechEmail" /></td>
       </tr>
        <tr>
            <td>Phone Number: </td>
            <td><input type="text" id="TechPhoneNumber" class="inputfield" @bind="@TechPhoneNumber" />
</td>
        </tr>
        <tr>
            <td colspan="2"><div align="center"><input class="techSubmit" type="button" 
@onclick="SaveProfile" value ="Save Profile Information" /></div></td>
        </tr>
    </table>

<span>@Message</span>


@code {
 
string Message = "";

protected override async Task OnInitializedAsync()
{
    TechName = await oLocalStore.GetItemAsync<string>("TechnicianName");
    TechID = await oLocalStore.GetItemAsync<string>("TechnicianID");
    TechPhoneNumber = await oLocalStore.GetItemAsync<string>("TechnicianPhoneNumber");
    TechEmail = await oLocalStore.GetItemAsync<string>("TechnicianEmail");
}

public async void SaveProfile()
{
    Message = "Profile Data Saved";
    await oLocalStore.SetItemAsync("TechnicianName", TechName);
    await oLocalStore.SetItemAsync("TechnicianID", TechID);
    await oLocalStore.SetItemAsync("TechnicianPhoneNumber", TechPhoneNumber);
    await oLocalStore.SetItemAsync("TechnicianEmail", TechEmail);
}
}
