Same error here.

Visual Studio Professional 2015. Version installed: 14.0.25431.01 Update 3 (with the KB3165756)

This wrong behaviour started after installing Azure SDK 2.9.6, that installs .NET Core stuff & .NET Core templates into Visual Studio 2015 (actually installed .NET Core Tools (Preview 2) 14.1.21111.0)

If you add Class Library (.NET Core) or Console Application (.NET Core) to your C# solution, the forms.cs become visible again in solution explorer

Before adding Class Library (.NET Core):

After Class Library (.NET Core) added to Solution:

There is something wrong with .NET Core stuff. Hopefully it fixes on future patches.

Answer 3

I encountered the same issue, not displaying my Form. What you should do is:

• /project_directory/project_name.csproj edit this file and make sure your_form_name.cs is like this:

Notice: first delete all records from this file with existing your_form_name.cs and add the following:

`<Compile Include="your_form_name.cs">
   <SubType>Form</SubType>
</Compile>
<Compile Include="your_form_name.Designer.cs">
   <DependentUpon>your_form_name.cs</DependentUpon>
</Compile>
   <EmbeddedResource Include="your_form_name.resx">
   <DependentUpon>your_form_name.cs</DependentUpon>
</EmbeddedResource>`

Open solution again and Form will be shown in your project once again.

Maybe its not best solution but after complete removing and installing Studio returns to its normal state.

Answer 5

I am using VS2019 and the same problem was for me. But I solved this issue. I used Visual Assist for VS2019 and after expiration I uninstalled it. After that I got this issue. So I re-installed it again and licensed it. Then, it works now.
